Goodman 38
CARBON MONOXIDE POISONING HAZARD
Special Warning for Installation of Furnace or Air Handling
Units in Enclosed Areas such as Garages, Utility Rooms or
Parking Areas.
Carbon monoxide producing devices (such as an
automobile, space heater, gas water heater, etc.) should
not be operated in enclosed areas such as unventilated
garages, utility rooms or parking areas because of the
danger of carbon monoxide (CO) poisoning resulting from
the exhaust emissions. If a furnace or air handler is
installed in an enclosed area such as a garage, utility room
or parking area and a carbon monoxide producing device is
operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO
poisoning which can occur if a carbon monoxide producing
device continues to operate in the enclosed area. Carbon
monoxide emissions can be (re)circulated throughout the
structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain
damage or death.

Make Gas Connections
NOTE: This unit is factory set to operate on Natural gas at the
altitudes shown on the rating plate.
WARNING
To avoid property damage, personal injury or death when
either using propane gas alone or at higher altitudes,
obtain and installGoodman
the proper 89
conversion kit(s). Failure to
do so can result in unsatisfactory operation and/or
equipment damage. High altitude kits are for U.S.
installations only and are not approved for use in Canada.
The rating plate is stamped with the model number, type of gas
and gas input rating. Make sure the unit is equipped to operate
on the type of gas available. Conversion to LP gas is permitted
with the use of the factory-authorized conversion kit LPT-00A.
10
NOTE: Inlet gas pressure must not exceed the maximum value
shown in the Inlet Gas Pressure chart.
Inlet Gas Pressure
Natural
Minimum: 5.0" W.C.
Maximum: 10.0" W.C.
Propane
Minimum: 11.0" W.C.
Maximum: 13.0" W.C.
The minimum supply pressure should not vary from that shown in
the Inlet Gas Pressure chart, because this could prevent the unit
from having dependable ignition. In addition, gas input to the
burners must not exceed the rated input shown on the rating
plate. Overfiring of the unit could result in premature heat
exchanger failure.
High Altitude Derate—U.S. Installations Only
IMPORTANT: The gas/electric units naturally derate with
altitude. Do not attempt to increase the firing rate by changing
orifices or increasing the manifold pressure. This can cause poor
combustion and equipment failure. At all altitudes, the manifold
pressure must be within 0.3" W.C. of that listed on the nameplate
for the fuel used. At all altitudes and with either fuel, the air
temperature rise must be within the range listed on the unit
nameplate.
Refer to the installation manual provided with the LP kit for
conversion from Natural gas to propane gas and for altitude
adjustments.
Use HA02 for installations above 2,000 ft (609.6 m).
Piping
IMPORTANT: To avoid possible unsatisfactory operation or
equipment damage due to underfiring of equipment, do not
undersize the Natural/propane gas piping from the meter/tank to
the unit. When sizing a trunk line, include all appliances on that
line that could be operated simultaneously.
The rating plate is stamped with the model number, type of gas
and gas input rating. Make sure the unit is equipped to operate
on the type of gas available. The gas line installation must comply
with local codes, or in the absence of local codes, with the latest
edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1.

8. The unit must be connected to the building piping by one of
the following methods:
■ Rigid metallic pipe and fittings
Refer to the “Proper Piping Practice” illustration for the general
layout at the unit. The following rules apply:
1. Use black iron pipe and fittings for the supply piping. The use
of a flex connector and/or copper piping is permitted as long
as it is in agreement with local codes.
2. Use pipe joint compound on male threads only. Pipe joint
compound must be resistant to the action of the fuel used.
3. Use ground joint unions.
4. Install a drip leg to trap dirt and moisture before it can enter
the gas control valve. The drip leg must be a minimum of 3"
(7.6 cm) long.
5. Use 2 pipe wrenches when making the connection to the gas
control valve to keep the valve from turning.
■
Semirigid metallic tubing and metallic fittings (aluminum
alloy tubing must not be used in exterior locations)
■
Listed gas appliance connectors used in accordance with
the terms of their listing that are completely in the same
room as the equipment
■
The connector or tubing must be protected against
physical and thermal damage. Aluminum alloy tubing and
connectors must be coated to avoid external corrosion
when in contact with masonry, plaster or insulation or are
subject to repeated wettings by liquids (water—not
rainwater, detergents or sewage).

NOTE: The unit gas supply entrance is factory sealed with plugs.
Keep plugs in place until gas supply is ready to be installed. Once
ready, replace the plugs with the supplied grommets and install
gas supply line.
Check Gas Piping
CAUTION
To prevent property damage or personal injury due to fire,
the following instructions must be performed regarding
gas connections Goodman
and pressure testing:
90
-The unit and its gas connections must be leak tested
before placing in operation. Because of the danger of
explosion or fire, never use a match or open flame to test
for leaks. Never exceed specified pressures for testing.
Higher pressure may damage gas control valve and cause
overfiring which may result in premature heat exchange
failure.
-The unit and its gas shutoff valve must be disconnected
from the gas supply during any pressure testing of that
system at test pressures in excess of ¹⁄₂ psig (3.48 kPa).
-This unit must be isolated from the gas supply system
by closing its manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures
equal to or less than ¹⁄₂ psig (3.48 kPa).
IMPORTANT:
■ The unit and its gas connections must be leak tested before
placing in operation.
■ Do not use a match or open flame to test for leaks.
■ Do not exceed specified pressures for testing.
12
There will be air in the gas supply line after testing for leaks on a
new installation. Therefore, the air must be bled from the line by
loosening the ground joint union until pure gas is expelled.
Tighten the ground joint union and wait for 5 minutes until all gas
has been dissipated in the air. Be certain there is no open flame in
the vicinity during air bleeding procedure. The unit is placed in
operation by closing the main electrical disconnect switch for the
unit.
Install Propane Gas
WARNING
To avoid property damage, personal injury or death due
to fire or explosion caused by Goodman
a propane gas 92
leak, install
a gas detecting warning device. Since rust can reduce the
level of odorant in propane gas, a gas detecting warning
device is the only reliable way to detect a propane gas
leak. Contact a local propane gas supplier about installing
a gas detecting warning device.
NOTE: Propane gas conversion kits must be installed to convert
units to propane gas.
A gas detecting warning system is the only reliable way to detect
a propane gas leak. Rust can reduce the level of odorant in
propane gas. Do not rely on your sense of smell. Contact a local
propane gas supplier about installing a gas detecting warning
system.
All propane gas equipment must conform to the safety standards
of the National Board of Fire Underwriters, NBFU Manual 58.
For satisfactory operation, propane gas supply pressure must be
within 9.7" W.C. to 10.3" W.C. at the furnace manifold with all gas
appliances in operation.
Maintaining proper gas pressure depends on 3 main factors:
■ Vaporization rate, depending on the temperature of the liquid
and the wetted surface area of the container or containers.
■ Proper pressure regulation. Two-stage regulation is
recommended for both cost and efficiency.
■ Pressure drop in the lines between the regulators, and
between 2nd stage regulator and the appliance. Pipe size
required will depend on the length of the pipe run and the
total load of all appliances.
Propane Gas Installation—Typical
Tanks and Piping
Complete information regarding tank sizing for vaporization,
recommended regulator settings, and pipe sizing is available
from most regulator manufacturers and propane gas suppliers.
Since propane gas will quickly dissolve white lead and most
standard commercial compounds, special pipe dope must be
used. Shellac-based compounds resistant to the actions of
liquefied petroleum gases are satisfactory.

due to fire or explosion caused by a propane gas leak,
Goodman
102device.
install a gas detecting
warning
If the propane gas unit is installed in an excavated area
or a confined space, a warning device is required due to:
-Propane gas is heavier than air and any leaking gas
can settle in any low areas or confined spaces.
-Propane gas odorant may fade, making the gas
undetectable except with a warning device.
Rollout Protection Control
The rollout protection device opens, cutting power to the gas
control valve, if the flames from the burners are not properly
drawn into the heat exchanger. The rollout protection device is
located on the burner bracket. The reason for elevated
temperatures at the control should be determined and repaired
prior to resetting this manual reset control.
WARNING
To avoid property damage, personal injury or death due
to fire or explosion, a qualifiedGoodman

IMPORTANT: Bubbles forming indicate a leak. Turn off gas
immediately and fix all leaks.
NOTE: For gas-to-gas conversion, consult your dealer for the
appropriate conversion.
Gas Input Check—Natural Gas Only
To measure the gas input, use a gas meter and proceed as
follows:
1. Turn off the gas supply to all other appliances except the unit.
2. With the unit operating, time the smallest dial on the meter for
1 complete revolution. If this is a 2 cu ft dial, divide the
seconds by 2; if it is a 1 cu ft dial, use the seconds as is. This
gives the seconds per cubic foot of gas being delivered to the
unit.
3. Input = Gas Heating Value x 3,600 / Sec. Per Cubic Foot
Example: Natural gas with a heating value of 1,000 Btu per
cubic foot and 34 seconds per cubic foot as determined by
Step 2, then:
Input = 1,000 x 3,600 / 34 = 106,000 Btu/h.
NOTE: Btu content of the gas should be obtained from the
gas supplier. This measured input must not be greater than
shown on the unit rating plate.
4. Turn on the gas supply to all other appliances turned off in
Step 1. Check that all pilot burners are operating.
Main Burner Flame Check
Flames should be stable, soft and blue (dust may cause orange
tips, but they must not be yellow) and extending directly outward
from the burner without curling, floating or lifting off.
Measure Temperature Rise
Check the temperature rise through the unit by placing
thermometers in supply and return air registers as close to the
unit as possible. Thermometers must not be able to sample
temperature directly from the unit heat exchangers, or false
readings could be obtained.
1. All registers must be open; all duct dampers must be in their
final (fully or partially open) position and the unit operated for
15 minutes before taking readings.
2. The temperature rise must be within the range specified on
the rating plate.
NOTE: Air temperature rise is the temperature difference
between supply and return air.
With a properly designed system, the proper amount of
temperature rise will normally be obtained when the unit is
operated at the rated input with the recommended blower speed.
If the correct amount of temperature rise is not obtained, it may
be necessary to change the blower speed. A higher blower speed
will lower the temperature rise. A slower blower speed will
increase the temperature rise.
NOTE: Blower speed must be set to give the correct air
temperature rise through the unit as marked on the rating plate.
External Static Pressure Check
The total external static pressure must be checked on this unit to
determine if the airflow is proper.

WARNING
This unit must Goodman
not be used 79
as a “construction heater”
during the finishing phases of construction on a new
structure. This type of use may result in premature failure
of the unit due to extremely low return air temperatures
and exposure to corrosive or very dirty atmospheres.
Unit Shutdown
1. Set the thermostat to the lowest setting.
2. Turn off the electrical power supply to the unit.
3. Remove the heat exchanger door on the side of the unit by
removing the screws.
4. Move the gas control valve switch to the OFF position.
NOTE: Do not force.
5. Close the manual gas shutoff valve external to the unit.
6. Replace the heat exchanger door on the unit.
7. If cooling and/or air circulation will be desired, turn on the
electrical power.
After completing the airflow measurements and adjustments, the
unit’s refrigerant charge must be checked. The unit comes
factory charged, but this charge is based on 325 CFM per ton
and minimum ESP per ARI test conditions (generally between
0.15 to 0.25 ESP). When air quantity or ESP is different than
above, the refrigerant charge must be adjusted to the proper
amount.
All package units with fixed orifice devices are charged using the
superheat method at the compressor suction line.
For charging in the warmer months, 8ºF ± 3ºF superheat at the
compressor is required at conditions 95ºF (35ºC) outdoor
ambient (dry bulb) temperature, 80ºF (27ºC) dry bulb / 67ºF
(19ºC) wet bulb indoor ambient temperature, approximately 50%
humidity. This superheat varies when conditions vary from the
conditions described.
After superheat is adjusted, it is recommended that subcooling
be checked at the condenser coil liquid line out. In most
operating conditions 10ºF to 15ºF of subcooling is adequate.
Cooling Refrigerant Charging—Models with TXV
Check the unit charge before putting the cooling section into full
operation. The unit is factory-charged with R-410A for nominal
airflow and static pressure conditions. The unit has a
thermostatic expansion valve (TXV) metering device. To ensure
that the unit is properly charged for the intended application,
check the unit refrigerant subcooling at the condenser. The
refrigerant subcooling is a function of outdoor ambient
temperature and return air temperature of the conditioned space.
It is the installing contractors responsibility to ensure that the
proper refrigerant subcooling at the condenser is adjusted for
each application. For example, 10ºF refrigerant subcooling level
is adequate for a 95ºF (35ºC) outdoor ambient temperature and
for a 78ºF to 80ºF (26ºC to 27ºC) indoor return air temperature.
As the outdoor ambient temperature rises, the subcooling
decreases, and as the outdoor ambient temperature lowers, the
subcooling increases.
NOTE: Proper subcooling adjustment optimizes cooling
performance.
19
On models equipped with a thermostatic expansion valve, charge
the system to 10º of subcooling. When necessary, adjust the
expansion valve stem for superheat setting.
NOTE: The expansion valve will not need adjustment for most
applications. Check that the system superheat is set between
12ºF and 15ºF after final adjustment.
Superheat Adjustment
1. To adjust superheat, remove the control box cover and locate
the expansion valve on the liquid line of the evaporator.
2. Unscrew the cover from the expansion valve
3. Locate the adjustment screw, and turn it clockwise (in) to
increase superheat or counterclockwise (out) to decrease
superheat.
4. Replace the adjustment cap.
5. Wait a minimum of 10 minutes between adjustments to allow
time for the TXV and pressures to stabilize.
Cooling Operation
NOTE: Mechanical cooling cannot be reliably provided at
ambient temperatures below 50°F (10ºC).
1. Turn on the electrical power supply to the unit.
2. Place the room thermostat selector switch in the COOL
position (or AUTO if available, and if automatic changeover
from cooling to heating is desired).
3. Set the room thermostat to the desired temperature.
SEQUENCE OF OPERATION
Heating System
This unit is equipped with an ignition control that automatically
lights the main burner.
NOTE: Do not attempt to light the main burners by any other
method.
1. Thermostat calls for low-stage or high-stage heating.
2. The induced draft blower energizes for a 15-second prepurge.
3. The spark igniter and low-stage and high-stage gas control
valves energizes for 7 seconds.
NOTE: The igniter produces a very intense electrical spark that
ignites the gas.
4. The main burners light, and the control detects the presence
of a flame.
5. If the call is for low-stage heat, the induced draft blower
switches to low speed and the high-stage gas control valve
closes 5 seconds after the main burners light. If the call is for
high-stage heat, the induced draft blower remains at high
speed and the high-stage gas control valve remains open.
NOTE: If a single-stage thermostat is used, the control will
step to low stage after the main burners light and remain at
low stage for 5 or 10 minutes, depending on the jumper
position. If the call for heat remains after the transition delay
time expires, the control will transition from low stage to high
stage.
6. The 30-second Heat Fan On delay time begins after the main
burners light.
7. The unit delivers heat to the conditioned space until the
thermostat is satisfied.
8. The gas control valve(s) de-energizes.
9. The induced draft blower continues operation for a
30-second post-purge.
10. The induced draft blower remains at low speed (or switches
from high to low, if operating at high stage heat) for the
30-second post-purge.
20
11. Ignition control begins timing the Heat Fan Off delay.
There is an adjustable Heat Fan Off delay of approximately
90/120/150/180 seconds (factory set at 150). If the unit is
operating at high stage when the call for heat is removed, the
blower will operate for 30 seconds at high-heat speed, and
then switch to low-heat speed for the remainder of the
selected Heat Fan Off delay.
After the Heat Fan Off delay time has elapsed, the induced
draft blower will de-energize. This allows any additional heat
in the heat exchanger to be transferred to the conditioned
space.
Cooling System
1. The thermostat calls for low- or high-stage cooling.
2. If the thermostat call is for low-stage cooling, the compressor
and outdoor fan are energized at low stage. If the thermostat
call is for high-stage cooling, the compressor and outdoor fan
are energized at high-stage cooling.
3. Approximately 6 seconds later, the indoor blower fan will
energize.
4. The unit will deliver cooling to the conditioned space until the
thermostat is satisfied.
5. The compressor and outdoor fan will be de-energized when
the thermostat opens.
6. The indoor blower fan continues to run at low-cool speed for
approximately 60 seconds after the thermostat is satisfied.
This allows additional cooling from the indoor coil to be
transferred to the conditioned space. Then, the indoor blower
fan is de-energized.
NOTE: A 180-second anti-short cycle is integral to the control
and prevents recycling of the compressor.
Fan Only
1. The thermostat calls for Fan Only by energizing “G.”
2. Immediately, the indoor blower fan Is energized at the
low-heat speed.
3. The indoor blower fan is immediately de-energized once the
thermostat call for Fan Only is removed.
Cooling Start-Up
NOTE: Check all manual reset limit controls in heating circuit if
cooling mode does not operate.
Compressor Protection Devices
The compressor includes components which are designed to
keep the compressor from abnormal operating conditions.
WARNING
Goodman
To prevent personal
injury or95
death, always disconnect
electrical power before inspecting or servicing the unit.
All compressor protection devices reset automatically,
energizing the contactor and outdoor fan.

Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
Have the gas heating section of the unit checked at least once a
year before the heating season begins, to be sure that the
combustion air inlet and flue outlet hoods are not blocked by
debris, which would block adequate combustion air and a keep
the vent system from operating properly.
Filter Replacement or Cleaning
A return air filter is not supplied with this unit; however, there
must be a means of filtering all of the return air. The filter(s) may
be located in the return air duct(s), or return air filter grille(s).
Consult with your installing dealer for the actual location of the
return air filter(s) for your unit.
Dirty filters are the most common cause of inadequate heating or
cooling performance. Filter inspection should be made at least
every 2 months; more often if necessary because of local
conditions and usage.
Dirty throwaway filters should be discarded and replaced with a
new, clean filter. Dirty permanent filters should be washed with
water, thoroughly dried and sprayed with a filter adhesive before
being reinstalled. (Filter adhesives may be found at many
hardware stores.) Permanent filters should last several years.
However, should one become torn or uncleanable, it should be
replaced.
Cabinet Finish Maintenance
Use a fine grade automotive wax on the cabinet finish to maintain
the finish’s original high luster. This is especially important in
installations with extended periods of direct sunlight.
Clean Outside Coil—Qualified Servicer Only
The coil with the outside air flowing over it should be inspected
annually and cleaned as frequently as necessary to keep the
finned areas free of lint, hair and debris.
Condenser, Evaporator and Induced Draft Motors
Bearings on the air circulating blower motor, condenser motor
and the combustion fan motor are permanently lubricated. No
additional oiling is required.
Flame Sensor (Qualified Servicer Only)
A drop in the flame current can be caused by a nearly invisible
coating on the flame sensor. This coating, created by the fuel or
combustion air supply, can be removed by gently cleaning the
flame sensor with steel wool.

Flue Passages—Qualified Servicer Only
At the start of each heating season, inspect and, if necessary,
clean the unit flue passage.
Cleaning Flue Passages—Qualified Servicer Only
1. Disconnect the electric power and gas supply to the unit.
2. Remove the burner assembly by disconnecting the gas line
and removing the manifold bracket from the partition panel.
3. Remove the flue from the induced draft blower and the
collector box cover from the partition panel.
4. The primary heat exchanger tubes can be cleaned using a
round wire brush attached to a length of high grade stainless
steel cable, such as drain cleanout cable. Attach a variable
speed reversible drill to the other end of the spring cable.
5. Slowly rotate the cable with the drill and insert it into one of
the primary heat exchanger tubes.
6. While reversing the drill, work the cable in and out several
times to obtain sufficient cleaning.
7. Use a large cable for the large tube, and then repeat the
operation with a small cable for the smaller tube. Repeat for
each tube.
8. When all heat exchanger tubes have been cleaned, replace
the parts in the reverse order in which they were removed.
9. To reduce the chances of repeated fouling of the heat
exchanger, perform the steps listed in “Start-Up, Adjustments
and Checks.”
Main Burner Flame—Qualified Servicer Only
Flames should be stable, soft and blue (dust may cause orange
tips but must not be yellow). The flames must extend directly
outward from the burner without curling, floating or lifting off.

The ignition control is equipped with a momentary pushbutton
switch that can be used to display on the diagnostic LED the last
5 faults detected by the control. The control must be in Standby
Mode (no thermostat inputs) to use the feature.
1. Depress the pushbutton switch for approximately 2 seconds.
NOTE: Do not hold for longer than 4 seconds. Holding the
button for 4 seconds or longer will erase the memory.
2. Release the switch when the LED is turned off. The
diagnostic LED will then display the flash codes associated
with the last 5 detected faults. The order of display is the
most recent fault to the least recent fault.
Abnormal Operation—Heating
Internal Control Failure—Status Light Off
If the integrated ignition control in this unit encounters an internal
fault, it will go into a “hard” lockout and turn off the diagnostic
LED.
If diagnostic LED indicates an internal fault,
■ Check the power supply to unit for proper voltage.
■ Check all fuses, circuit breakers and wiring.
■ Disconnect electric power for 5 seconds. If LED remains off
after restoring power, replace control.
External Lockout—1 Flash (Red LED)
An external lockout occurs if the integrated ignition control
determines that a measurable combustion cannot be established
within 3 consecutive ignition attempts. If flame is not established
within the 7-second trial for ignition, the gas control valve is deenergized, 30-second inter-purge cycle is completed, and
ignition is reattempted. The control will repeat this routine 3 times
if a measurable combustion is not established. The control will
then turn off the induced draft blower and go into a lockout state.
If flame is established but lost, the control will energize the
circulator blower at the heat speed and then begin a new ignition
sequence. If flame is established then lost on subsequent
attempts, the control will recycle for 4 consecutive ignition
attempts (5 attempts total) before locking out.
The diagnostic fault code is 1 flash for a lockout due to failed
ignition attempts or flame dropouts. The integrated control will
automatically reset after 1 hour, or it can be reset by removing the
thermostat signal or disconnecting the electrical power supply for
over 5 seconds.
If diagnostic red LED indicates an external Lockout,
perform the following checks:
Check the supply and manifold pressures.
Check the gas orifices for debris.
■ Check the gas control valve for proper operation.
■ Check the flame sensor. A drop in flame signal can be caused
by nearly invisible coating on the sensor. Remove the sensor
and carefully clean with steel wool.
■ Check the wiring. Check wiring for opens/shorts and
incorrect wiring.
IMPORTANT: If you have to frequently reset your gas/electric
package unit, it means that a problem exists that should be
corrected. Contact a qualified servicer for further information.

Rollout Limit Switch
Pressure Switch Stuck Open—2 Flashes (Red LED)
Causes:
■ Faulty pressure switch
■
Faulty wiring
■
Disconnected or damaged hose
■
Blocked or restricted flue
■
Faulty induced draft blower
If the control senses an open pressure switch during the prepurge cycle, the induced draft blower will be energized only.
If the pressure switch opens after ignition has begun, the gas
control valve is de-energized, the circulator blower Heat Off cycle
begins and the induced draft blower remains on.
Pressure Switch Stuck Closed—3 Flashes (Red LED)
Causes:
■ Faulty pressure switch
■ Faulty wiring
If the control encounters a pressure switch stuck closed, the
induced draft blower remains off.
Open Thermal Protection Device—4 Flashes (Red LED)
If a limit switch opens, the gas control valve is immediately deenergized, and the induced draft and air circulating blowers are
energized. The induced draft and air circulator blowers remain
energized until the limit switch closes again.
Primary Limit Switch
A primary limit switch will open due to excessive supply air
temperatures possibly caused by:
■ A dirty filter—Check filters.
■ Excessive duct static—Check total external duct static.
■ Insufficient airflow—Check blower motor and motor speed
tap (see wiring diagram).
■ A faulty limit switch—Check limit switch
NOTE: This limit switch will automatically reset once the
temperature falls below a preset level.
Auxiliary/Secondary Limit Switch
An auxiliary/secondary limit switch will open due to:
■ A dirty filter—Check filters.
■ Excessive duct static—Check total external duct static.
■ Insufficient airflow—Check circulator blower motor and motor
speed tap (see wiring diagram).
■ A faulty limit switch—Check limit switch.
■ A failed circulator blower—Replace circulator blower.
■ An interruption in electrical power during a heating cycle—
Automatic reset secondary limit switch is located on top of
the circulator blower assembly.
If the burner flames are not properly drawn into the heat
exchanger, the flame rollout protection device will open. Possible
causes are
■ Restricted or blocked flue passages.
■ Blocked or cracked heat exchanger
■ Failed induced draft blower
■ Insufficient combustion air.
NOTE: The rollout limit switch is a manual reset limit switch
located on the burner bracket. The cause of the flame rollout
must be determined and corrected before resetting the limit.
Flame Detected with Gas Control Valve Closed—5
Flashes (Red LED)—2 Flashes (Amber LED)
If a flame is detected with the gas control valve de-energized, the
combustion and air circulator blowers are energized.
The control can be reset by removing the power supply to the
unit or it will automatically reset after 1 hour. Incorrect wiring is
the probable cause for this fault.
Low Flame Signal—1 Flash (Amber LED)
Under some conditions, the fuel or air supply can create a nearly
invisible coating on the flame sensor. This coating acts as an
insulator causing a drop in the flame signal. If the flame signal
drops below a predetermined value, the ignition control will
display an error code of (1) flash on the amber diagnostic LED.
The unit will continue to operate until the control can no longer
detect flame.
Abnormal Operation—Cooling
Short Cycle Compressor Delay—6 Flashes (Red LED)
The automatic ignition control has a built-in feature that prevents
damage to the compressor in short cycling situations. In the
event of intermittent power losses or intermittent thermostat
operation, the ignition control will delay output to the compressor
contactor for 3 minutes from the time power is restored or
thermostat call for cooling is restored. Compressor is off a total of
3 minutes.
NOTE: Some electronic thermostats also have a built-in
compressor short cycle timer that may be longer than the
3-minute delay given above. If you are using an electronic
thermostat and the compressor has not started after 3 minutes,
wait an additional 5 minutes to allow the thermostat to complete
its short cycle delay time.
High Pressure Switch/Loss of Charge Switch—9 Flashes
(Red LED)
Some models include a high pressure cutout switch and/or a loss
of charge cutout switch. The high pressure cutout switch
protects the refrigeration system from excessive operating
pressures. The loss of charge cutout switch protects the
refrigeration system from very low operating pressures due to a
loss of refrigerant. Compressor operation will be disabled if either
of these devices opens.
