All Electric Range
Electrical Connections:
Range requires a 30 Amp (at least) 120 / 240 VAC or 120 / 208 VAC dedicated circuit preferably with
a four wire connection, however where local codes and ordinances permit grounding through the
neutral and / or conversion to four wire is impractical, unit may be connected to the power supply via a
three wire connection.
Connection can be made via a range cord or a flexible conduit. If a range cord is used it must meet the
above rating requirements and be marked “For use with Ranges.”

Instructions were determined using Standard American base cabinets measuring 36” high x 24”
deep. If nonstandard cabinets are used, care should be taken to alter dimensions accordingly.
NOTICE: Some cabinet finishes cannot service the temperatures allowed by U.L., particularly selfcleaning ovens; the cabinets may discolor or stain. This is most noticeable with laminated cabinets

Touch Bake and set temperature at the control, relay board receives input and
checks resistance of sensor. If heat is required then the following relays will close:
K3 & K4 for the bake element and K1 & K2 for the broil element. The output
voltages from the board should be as follows: X15-L1 to bake element, X16-L2 to
bake element. X11-L1 to broil element, X12-L2 to broil element. This supplies
120volts from L1 & L2 giving each element 240 volts and oven heats.

Touch Bake and set temperature at the control, relay board
receives input and checks resistance of sensor. If heat is required
then Bake relay K11 is closed. 120VAC is sent to the gas safety
valve. The glow igniter which is wired in series with the valve starts
to heat up, as it does so the voltage drops across the valve. When
the glow bar draws 3.2 amps and is glowing the valve opens
sending gas to the burner and it ignites. Bake is 17,000 BTUs.

LATCH FAILURE MODE
Error 41 Locking mode – All heating functions stop with error indicated
• If the latch does not lock and the control does not see a changed state of the feedback switch
(probably indicating that the motor did not rotate), the display will fault out and the latch motor shuts
off.
• If the control senses that contact A is open and B is still open (possibly due to disconnected wire or
bad switch), the control will fault out and the motor will continue to operate until the cam returns to
home position – contact A closed.
• If the control senses that contact B is closed and contact A remains closed (possibly due to bad
switch), the control will fault out and the motor will continue to operate until contact B is open again
(back to home).
Error 43 Unlocking mode – All heating functions should be off
• If the latch does not unlock and the control does not see a changed state of the feedback switch
(due to motor not rotating), the display will fault out and the latch motor shuts off.
• If the control senses that contact B is open and A is still open, the control will fault out and the motor
shuts off (should be in home position).
• If the control senses that contact A is closed and contact B remains closed, the control will fault out
and the motor shuts off.

LATCH FAILURE MODE Cont'd
Error 45 Locked and Unlocked mode – All heating functions should shut off
If the control senses that contacts A and B are either both open or both closed during any operation
(cooking or self-cleaning), the display will fault out and the latch motor will not rotate until the oven temp
is below 585o F. The control will then look for contact A open and contact B closed. If it does not find
that state within 1 minute, the control will look for Contact B closed and shut off the motor.
The user can press the cancel button once and the beep will stop and the display and control will go t
home state. If the latch is not in the home state when power is applied (or reapplied after a power
outage), the control will reset the latch to home without a beep alarm or display error message. This is
important if the latch was not in the home position when powered down or if the latch moved during
shipping from the factory.
When self-clean or delayed self-clean is started, the lock will activate immediately. While self-clean is
active, the oven lights and warming drawer are switched off and cannot be switched on until the
conclusion of self-clean. If the door is opened before the door is locked, the control will pause heating,
flash CLOSE DOOR and the beeper will produce a reminder tone. The latch will return to home position
and pause until the door is closed. The user will then have 60 sec. to close the door and allow the
control to complete the operation. After 60 sec. the display will show SELF CLEAN END. After
acknowledge (start or cancel), the controls resets to home state.

After the oven has cooled down and the door lock unlatches at the unlock set temperature, the
operator can open the door without the display showing CLOSE DOOR. The cool down time of
the cycle continues to operate until it times out or CANCEL is pressed.
If the self-clean cycle has been started and the user decides to CANCEL, if the oven is above
the unlock temperature, the oven stays in the locked condition and stays locked until the oven
temp falls below the unlock temperature. During this time, the user can only access the warming
drawer. Once the door unlocks all cooking functions are available.
If CANCEL is pressed before the unlock temperature is reached, the display clears and the door
unlocks and the control returns to home state.
If any Timers are operating they are to be cancelled or disabled while in self-clean mode.
The control is programmed with an unlock setting of 300o F.

BASIC (300 SERIES) RANGE CONTROL (FSR3 Only)
The specification for the Basic range consist of utilizing the same FSR3 interface and power
board hardware, however with less features for electric and gas application. The construction of
the range reflects the features offered (or not offered). The features, operations and all safety
protocols are identical to the standard FSR except for the following:
BAKE MODE – The bake mode is activated by the upper right zone (COOKING ZONE of the
standard FSR control). When this zone is selected, the control shows bake flashing and the
temp defaults to 350o F. The rotation knob is used to adjust the temp from 200o F to 525o F.
Rotation of the knob counter-clockwise past 200o F displays WARM HIGH, WARM LOW and
PROOFING. The START zone activates the mode. To assure that the control has the two-step
activation, there is no automatic start up. When the operator selects the bake zone the START
zone must be selected regardless if the temp was adjusted or not. The operating
limits/parameters for warm high, and proofing incorporates the base limits, using the set temps.
BROIL MODE – The broil mode is activated by the middle right zone (TEMPERATURE ZONE of
the standard control). When this zone is selected, the control shows Broil flashing and the temp
defaults to HI. Rotating the knob adjusts the temp from HI to LOW. When the operator selects
the BROIL zone, the START zone must be selected regardless if the temp was adjusted or not.
SELF CLEAN MODE – The self cleaning mode is activated by holding the upper right zone and
the middle right zone for 5 seconds. The only other variation to this mode is the control does not
have the convection fan (no convection cooking features).

TIMER MODE – The time modes remain the same. The selection and setting is identical to the
standard FSR control for all features. Time delay is the same.
Changing Temperature Settings
To change the temperature of Bake or Broil, the operator touches that zone. The temperature
numerical display (orange) displays the current setting and flash. Rotate the knob to select the
new temperature and then press the START zone to initiate. If the user does not rotate the knob
within 5 seconds, the control will revert back to the original temperature setting. If the knob is
rotated but the START zone is not pressed within 5 seconds, the control will set to the new
temperature setting.

FAQs – FREQUENTLY ASKED QUESTIONS
When is the convection fan for convection bake and convection roast
supposed to come on? When the temperature is reached or is it timed?
Gas Range – The convection fan does not come on while in preheat for Convection Bake &
Convection Roast, but will turn on when the preset temperature is reached OR at 6 minutes
(whichever is longer).

During Dehydrate, only the bake burner is used and a delay of 6 minutes will occur before the
convection fan turns on.
During self-clean, the broil burner is on first without the convection fan. Then the bake burner
turns on (the broil burner turns off). The convection fan turns on 6 minutes after the bake burner
turns on.
Electric Range – The convection fan comes on at the beginning of all convection modes.

FAQs – FREQUENTLY ASKED QUESTIONS Cont'd
What is the difference between convection bake and convection roast?
Gas Range
• Convection bake uses heat from the lower burner. The convection fan circulates the heat.
• Convection roast also uses heat from the lower burner and uses the convection fan to
circulate heat. In convection roast, the burner will cycle more often than in convection bake
because the temp is kept closer to the set temperature.
Electric Range (HES Series)
Better-Best Models
• Convection bake uses heat from the lower heating element and a third element located
behind the back wall. The convection fan circulates the heat
NOTE: The broil element operates during preheat but not while cooking.
• Convection roast uses heat from the top and bottom elements as well as heat circulated by
the convection fan.

How do you get the door light to remain on after opening and shutting the door?
Gas and Electric Range (all models)
The oven light can only be turned on manually using the control panel. Once the door is opened
and closed, the light will turn off and you must use the control panel to turn it on again.

Correct method of applying thread sealing compound
Pre-assemble the two fittings loosely.
Apply a small amount of compound
in one spot on threads at junction of
the two fittings using a small, rigid
instrument (piece of coat hanger,
welding rod, etc.).
DO NOT SPREAD – The action of
tightening the two parts together will
spread the compound between the
threads, in two to three revolutions.
