Refrigerator Sequence of Operation

Gas Supply
11” w.c. of pressure on the LP gas input to the gas solenoid valve is necessary

+12VDC Battery or
Filtered AC/DC
Converter
DC Voltage source to the refrigerator terminal block connection. This voltage can be
nominally +12V or +13.8V. The voltage range is 9.0VDC – 15.4VDC. The output of
an AC/DC converter must be regulated and filtered. A simple battery charger is not allowed.

POWER ON
Pushbutton
This is located on the display board on the front of the refrigerator. Pressing this pushbutton
turns on the refrigerator control and turns this pushbutton surface blue. This pushbutton turns on a
3.3v regulator on the control board in the back of the refrigerator which powers the processor and begins
execution of the refrigerator program. Even with the refrigerator control OFF, there is +12V present and
120VAC present on portions of the control board however no refrigerator outputs are active.

Thermal Cutoff
Switch
There is a bimetal thermal cutoff switch which has normally closed contacts located on the
metal canister approximately 8” above the burner box. This switch’s contact will open in the unlikely
event that the temperature in the generator section of the cooling system (located directly behind the
thermal switch) reaches an unsafe temperature. This will turn off +12V to all of the refrigerator outputs –
turning them OFF and the display board in the front of the refrigerator will light the CHECK indicator and
all of the MODE indicators across the top of the display board. This error code will continue to be
displayed until the thermal switch contacts are closed. When the abnormally high, unsafe temperature is
returned to a safe operating temperature – the thermal switch can be reset by pressing a pushbutton
which extends between the two terminals on the back of the unit. Should this switch’s contacts open a
second time – the refrigerator should be turned OFF and an authorized Atwood service technician should
be contacted.

Refrigerator
Electronic
Control boards
The Atwood refrigerator control consists of two electronic boards: the display board in the
front of the refrigerator which the owner can select various modes of operation and adjust
the temperature settings and the control board which is mounted inside a protective plastic
box on the back of the refrigerator. Both boards have their own individual processors and execute their
own programs. They communicate to each other across a 5-wire connection.
When the POWER ON pushbutton is pressed and the control turns on, the display board is actually
communicating to the control board in back of the refrigerator. When the MODE pushbutton is pressed
and manual AC is selected, the display board communicates that choice back to the control board and
the control board de-energizing the gas control value and energizing the AC relay which places 120VAC
on the AC heater. When the AUTO MODE is selected, the refrigerator control automatically selects AC
if AC is present, otherwise the control automatically selects GAS if present. A more complete description
of the refrigerator control is given in the IOM owner’s manual and also later in this manual.
 AC MODE
If AC is present – the AC relay is energized on
the control board and AC voltage is placed on
the AC heater. The amperage draw should be
2.6 amps (2.3 – 3.0 range) with 115VAC applied
for heaters rated 300w @ 115VAC. This is the
preferred heater. Earlier refrigerator models used
heaters rated 300w @ 120VAC which delivers
less current (2.3 amps typical) and less power.
Whenever AC is ON – the gas solenoid valve
should be OFF. (Ref pg. 8 for date code information)
Rev 9 – May 29, 2014
5
• GAS MODE
The control will begin 40 second ignition trial
(20 sec spark, 2 sec pause, 10 sec spark, 2 sec
pause, 6 sec spark). If the burner is not lit, the control
will display CHECK light constant ON and the GAS
Indicator will flash indicating that no ignition occurred.
This can be reset by turning the refrigerator OFF and
then ON again and a new 40 sec ignition trial will be
initiated. Whenever the gas solenoid is ON – the AC
heater should be OFF.
CONTROL PANEL
The refrigerator control panel is located between the fresh
food and freezer compartments of your refrigerator. The
refrigerator control requires +12 volts DC to operate. There
are three pushbuttons.
POWER ON – Pressing this pushbutton turns the refrigerator
on and off.
MODE – Pressing and holding this pushbutton cycles the
mode selections from AUTO, manual GAS, and manual AC.
Releasing the pushbutton selects the last mode displayed.
The selected mode will be displayed for approx 5 seconds
before all the mode indicators are turned off. The active
mode can be displayed at any time by pressing and releasing
the MODE pushbutton.
TEMP – Pressing and holding this pushbutton cycles the
temperature settings from 1 through 5 with 5 being the
maximum cool setting. Releasing the pushbutton selects the
last temperature setting displayed. The selected temperature
setting will be displayed for approx 5 seconds before all the
temperature indicators are turned off. The active
temperature setting can be displayed at any time by pressing
and releasing the TEMP pushbutton.
AUTO MODE
When the refrigerator is in the AUTO mode, the control
automatically selects the best energy source which is
available. When a more efficient energy source becomes
available, the refrigerator automatically switches to the more
efficient source. AC energy is considered the more efficient
energy source and is the first choice selected by the control.
Propane gas is the second choice and is selected in the
AUTO mode only when AC energy is not available.
GAS MODE
The GAS mode can be selected either automatically or
manually. When switching to gas operation, the refrigerator
control begins a 40 second trial ignition cycle. During this
period, the control opens the gas safety valve and begins
sparking the burner. If after 40 seconds the control fails to
detect the presence of a flame, the control shuts off the gas
safety valve and stops sparking the burner. The CHECK
indicator on the control panel turns on indicating that the
burner failed to ignite. The CHECK indicator can be reset by
turning the refrigerator off and then back on again and a new
40 second trial ignition cycle begins. On initial start up or
after changing a propane tank, it is possible that air in the
gas supply lines will require 2 or 3 ignition trials before
successfully lighting the burner. If after repeated attempts,
the burner fails to ignite, stop and consult your local dealer or
an authorized Atwood Service Center.
MANUAL MODES
The manual modes allow for selection of either the AC or
GAS modes directly. If the selected mode’s energy source is
not available, the refrigerator is turned off, the CHECK is
turned on and the selected mode indicator flashes on and off
indicating which energy source is not available.

DOOR HANDLES
The door handles latch when closed to prevent the doors
from opening during travel. When closing the doors, push
each door into the refrigerator cabinet until you hear a distinct
“click” sound which will indicate that the door is latched. To
open a door, pull the handle away from the refrigerator
cabinet to unlatch the handle.
During off-season storage, the handle has a storage latch
which prevents the door from completely closing. Keeping
the doors partially opened during long term storage prevents
odors from building up in the cabinet. To engage the storage
latch, open each door about 1/2 inch, hold the door handle in
the open position, and push the storage latch into the cutout
of the strike plate. Never use the storage latch as a travel
latch because the doors will not be fully closed.
DOOR AJAR ALARM
This refrigerator has an alarm to alert you if the fresh food
compartment door is not fully closed. If the door is left open
for more than 2 minutes, the CHECK light will be lit and a
beeper will sound a chirp approx every 5 seconds until the
door is closed.
The refrigerator will continue to operate normally throughout
the door ajar alarm sequence.
MOISTURE DIVIDER HEATER
This refrigerator has a heater which is automatically
controlled and prevents moisture from forming on the center
divider located between the freezer and fresh food
compartments.
BACKUP TEMPERATURE CONTROL SYSTEM
This refrigerator has a backup temperature control system
which allows the owner to have variable temperature control
of the refrigerator even if the temperature sensor should fail.
If the control cannot read the temperature sensor, the control
uses the last selected temperature setting to control the
refrigerator duty cycle and adjust the temperature
accordingly.
THERMAL SWITCH MONITOR
This refrigerator has a thermal switch which serves as an
overheating monitor.
TILT SENSOR TECHNOLOGY
This refrigerator control incorporates a patent pending tilt
sensor which enables the control to constantly monitor the
angle at which the refrigerator is operated. This feature
protects the user from potential hazards attributed to
prolonged operation at severe angles of inclination. This
monitoring function is completely invisible to the user and
only becomes apparent to the user in the rare event that the
refrigerator has been operated for prolonged periods of time
at severe tilt angles. Normal care in leveling of your vehicle
will prevent this feature from ever being noticed.
Troubleshooting Guide
Control Display Panel Fault Table
The refrigerator’s electronic control provides “fault codes” for a variety of fault conditions.
For example, if the thermal switch located on the canister just above the burner box reaches an abnormally
high temperature, the thermal switch “opens” and the control display panel lights up the following indicators:
CHECK, AUTO, GAS, AC, DC and they remain ON when the control is powered ON. In addition, all the power
source outputs (the AC relay and the GAS valve relay output) are all disabled.
Another example, if the refrigerator is in GAS mode and the burner fails to ignite in the 45 seconds allowed,
the control display panel turns on the CHECK indicator, it flashes the GAS indicator, and the beeper sounds a
beep lasting 240ms.
A third example, if the door is left open for longer than 2 minutes, the CHECK indicator flashes and the
beeper sounds a very short beep approximately every 2 seconds.
The table below provides a complete listing of all of these fault codes.

Temperature Setting Setpoints
There is a high temperature TURN ON setpoint and a low temperature TURNOFF setpoint associated with each
temperature setting. The corresponding voltage at the input pin (J10-1) is listed for each temperature point.
This results in an average temperature for each setting given in the small table on the right. Please note that this
is the average temperature for the FIN - the average CABINET AIR temperature will be approximately 6-8 degrees
warmer than the FIN temperature.
The table above is for troubleshooting the thermistor circuit with in-circuit voltage measurements (ie. with the
connectors installed and with power on).
The thermistor circuit can also be troubleshot by measuring the resistance on the thermistor directly across pins
1 and 2 on the J10 connector with power off and with the J-10 connector disconnected from the control board.
For the following fin temperatures – the thermistor should have the following resistance measurements:

Condition
Poor Cooling
INFORMATION GATHERING
First – we need to define what is meant by “poor cooling”.
1) What are the outside ambient conditions? Direct sunlight on vehicle?
2) What are the temperatures in the freezer air and the cabinet air?
3) Is there reported frost buildup in cabinet or freezer?
4) Is the cabinet level?
5) What is power source? Does problem happen with AC and GAS?
6) Is there evidence of “frosted elbow” (ie. cooling not being used up)
7) Is there adequate ventilation? (ie, no blockages, etc)
Verify: In AC mode, verify AC heater is energized with 2.6amps. If not replace
with a heater rated 300w @ 115VAC. Refrigerators with date codes after
131210 (Dec 10, 2013) should already have heaters rated 300w @115VAC.
HEATER NOTE: Heaters installed prior to Dec 10, 2013 were rated to
be 300 watts @ 120VAC. The resistance of these older heaters when
disconnected from the control board and measured directly should be
48 ohms (+/- 4 ohms). Heaters installed after Dec 10, 2013 are rated to
be 300 watts @ 115VAC. The resistance of these newer heaters when
disconnected from the control board and measured directly should be
44 ohms (+/- 4 ohms).
Verify: In GAS mode, that burner is being ignited and flame has good
shape and color
Next: Attempt to get accurate temp data
1) Suggest running cabinet overnight with thermometers placed
2) Get thermocouple data if possible
3) Have dealers/service centers run cabinet outside of RV overnight
Poor Cooling
1) Refrigerators perform poorly in 100-110˚F; especially in direct sunlight
These refrigerators may perform normally in 90˚F
2) Door gasket leakage can lead to abnormal high internal temperatures
3) Leakage generally caused by door mis-alignment or poor gaskets
4) Off level cabinets inhibit good absorber/condenser function (3˚ angle)
5) If one power source is worse – focus on that power source
6) Suggests poor evaporator tube contact in freezer and/or cabinet fin
7) Poor ventilation directly affects cooling performance
8) AC heater may not be delivering full power (ie damaged, open circuit)
8a) Incoming AC power may be below 110VAC (90-100 VAC problematic)
9) Gas pressure may not be 11”wc; burner may be misaligned if the
flame wicks up along the side of the flue

DIAGNOSTIC MODE WORK INSTRUCTION OF REFRIGERATOR rev 1
(NOTE: The diagnostic mode is only accessible from a normal, power on condition)
1. Make sure the refrigerator is powered on and functioning normally.
2. To enter the Diagnostic Mode, perform the following steps:
1. Press and hold both the TEMP and MODE pushbuttons together while watching the LEDs on the left
hand side of the display board;
2. After about 2 seconds of holding both pushbuttons down, both the CHECK LED and the leftmost bar
indicator on the temperature setting LEDs will turn on.
3. Release both the TEMP and MODE pushbuttons within 1 second of the two LEDs becoming lit and
the display will be in the diagnostic mode.
a) The CHECK and the leftmost bar both ON indicates that the display is in diagnostic mode
b) The AUTO, GAS, and AC LEDs indicate the contents of the stress level counter in binary
with the AC indicator being the least significant bit and the AUTO indicator being the most
significant bit
c) The 3 LEDs on the right-hand side of the temperature setting LEDs indicate the tilt position
angle of the power board in binary with the rightmost LED being the least significant bit.
4. To exit the diagnostic mode and return to normal operation, press either the MODE or TEMP buttons.
DIAGNOSTIC MODE
(Both LEDs ON)
STRESS LEVEL COUNTER
(Binary Indication)
TILT ANGLE POSITION
(Binary Indication)
4. Normally the tilt angle position is zero (all LEDs OFF) when the powerboard is mounted on the
refrigerator and the refrigerator is standing vertical. As the powerboard is tilted approximately 5
degrees either to the right or the left, one rightmost LED will light. As the powerboard is tilted to 10
and 15 degree angles off of vertical, the tilt position will count up in binary to “010” and “011”
respectively. When the refrigerator is returned to the vertical position, all three LEDs should again be
OFF. This indicates that the tilt sensor is performing normally. If none of the LEDs turn on as the
refrigerator is tilted thru these angles – you should contact an authorized service center immediately.
If when the refrigerator and the powerboard are standing vertical and all three of the LEDs are not
OFF – this indicates that the tilt calibration procedure may need to be performed. Please contact an
authorized service center.
5. Normally the stress level counter is zero (all LEDs OFF) indicating that the control has not been
operated at severe position angles for any length of time. It is possible that the counter might display
“001” or a “010” – this indicates that the refrigerator had been operated at a severe angle for short
periods of time. The owner should be alerted that better care of leveling needs to be taken when
operating his refrigerator particularly during long-term storage. If the counter displays “110” or
“111” - the owner should contact an authorized service center immediately as the refrigerator has
been operated for long periods of time at severe position angles.

Control Sequence of Operation
The ON/OFF pushbutton allows the refrigerator control to power up. The indicator lights on the display board will light up
and display the MODE and the current TEMP SETTING.
The refrigerator will be in one of three modes: AC manual mode, GAS manual mode, AUTO mode
AC Manual Mode
If the cabinet temperature is higher than 60°F, then 110VAC is applied to the AC heater and 110VAC can
be read across terminals J11 and J13. The AC heater creates heat inside the generator portion of the
cooling system (inside the canister) which causes the cabinet fin to get colder which in turn lowers the
temperature in the freezer and the refrigerator cabinet. The cabinet will continue to get colder until it
reaches the LOW TEMP to TURN OFF thermostatic setpoint determined by the TEMP SETTING 1 thru 5
as detailed on the table on page 7.
When the cabinet fin temperature reaches the lowest point for the selected TEMP SETTING – 110VAC is
removed from the AC heater resulting in a reading of 0 VAC across the terminals J11 and J13. The AC
heater remains OFF until the cabinet fin temperature rises to the HIGH TEMP to TURN ON thermostatic
setpoint determined by the TEMP SETTING 1 thru 5 as detailed on the table on page 7.
There is a high temperature cut-off switch which is located on the canister several inches above the
burner box. This switch is normally CLOSED. The +12VDC power for the output drivers on the control
board is routed thru this switch. If the cooling system has an abnormally high generator temperature the
high temperature cut-off switch OPENS and +12VDC is removed to the output drivers – disabling and
turning OFF both the AC heater and the gas solenoid valve. The display board will light the CHECK light
and all of the mode indicator lights across the top of the display board.
GAS Manual Mode
If the cabinet temperature is higher than 60°F, the GAS solenoid valve is energized and the control begins a 40
second ignition trial period. During this 40 second time period, the control attempts to ignite the burner. During
this 40 second time period there are 3 separate bursts of ignition tries, specifically a 20 sec burst followed by a
short pause followed by a second 10 sec burst followed by a short pause followed by a third 8 sec burst. If after
40 seconds the control cannot ignite the burner, then the control enters a CHECK mode with the CHECK indicator
light being lit, the GAS indicator light flashes, and the gas solenoid valve is de-energized. This can be reset by
turning OFF the refrigerator for 5 seconds and then turning the refrigerator back ON and the 40 second ignition
trial begins again.
Once the burner is ignited, the gas burner creates heat inside the generator portion of the cooling system (inside
the canister) which causes the cabinet fin to get colder which in turn lowers the temperature in the freezer and the
refrigerator cabinet. The cabinet will continue to get colder until it reaches the LOW TEMP to TURN OFF
thermostat setpoint determined by the TEMP SETTING 1 thru 5 as detailed on the table on page 7.
When the cabinet fin temperature reaches the lowest point for the selected TEMP SETTING – the gas solenoid
valve is shut off and the flame at the burner is extinguished. The gas burner remains OFF until the cabinet fin
temperature rises to the HIGH TEMP to TURN ON thermostatic setpoint determined by the TEMP SETTING 1
thru 5 as detailed on the table on page 7.
There is a high temperature cut-off switch which is located on the canister several inches above the burner box.
This switch is normally CLOSED. The +12VDC power for the output drivers on the control board is routed thru
this switch. If the cooling system has an abnormally high generator temperature the high temperature cut-off
switch OPENS and +12VDC is removed to the output drivers – disabling and turning OFF both the AC heater and
the gas solenoid valve. The display board will light the CHECK light and all of the mode indicator lights across the
top of the display board.
AUTO Mode
In the Automatic mode, if AC is present and available to the control board – the control goes into AC mode and energizes
the AC heater in the same manner as in the AC Manual mode. If AC is not available, the control automatically switches
into GAS mode and energizes the gas solenoid valve and begins a 40 sec ignition trial in the same manner as the GAS
Manual Mode. The only difference is that is AC becomes available while the refrigerator is in AUTO GAS, the control
switches automatically to AUTO AC mode.
