SPEED BAKE MODE (some models)
The speed bake oven uses the addition of a fan to move the air already in the oven. Moving the heated air helps to
destratify the heat and cause uniform heat distribution. Cooking times can be reduced by as much as 30%. The air
is drawn in through a fan shroud located on the rear wall of the oven. It is then discharged around the outer edges
of this shroud. The air circulates around the food and then enters the shroud again. There is still an oven vent which
discharges through the bottom of the control panel.
To set the control in speed bake mode, follow these steps:
1.Press the SPEED BAKE pad.
2. Enter the desired temperature on the keypad (set point).
3. Press the START pad.
The oven will automatically start and the fan will begin to run. To cancel the speed bake function, press the CANCEL
pad.
NOTE: The fan runs continuously while in the speed bake mode. The fan will stop if the door is opened. The bake
element or burner will continue to operate if the door is opened.
PREHEAT
During a preheat mode, the oven uses a bake element or burner to reach the controller set point. The element uses
full power when it's on. When the set point is reached, the preheat mode is converted to a normal bake mode.
NORMAL BAKE
Electric Oven Models: During a normal bake mode, the controller preheats the oven with the bake element. When
the desired temperature is reached, the controller adds top heat by cycling the broil element on for 12 to 18 seconds
per minute. The bake element is on for the remaining time of the minute. Both elements use full power when they
are on but they are never on at the same time. Gas Oven Models: During a normal bake mode, the controller preheats
the oven with the bake burner.
CLEAN
During a cleaning process, the oven uses bake element or burner.
CLEAN AND TIMED CLEAN
When these modes are selected, the door locks right after start button is pushed.
FIRST RISE
It is normal to see a temperature overshoot in the
first rise of all modes when you monitor the temperature.

OVEN CALIBRATION
Set the electronic oven control for normal baking at 350°F/176°C. Obtain an average oven temperature after a
minimum of 5 cycles. Press Cancel to end bake mode.
Note: Changing calibration affects all the cooking modes but not the clean mode.

when the power is reapplied, replace EOC. Severe overheating
may require the entire oven to be replaced, should damage
be extensive.
2. Press CLEAR key.
3. Disconnect power, wait 30 seconds and reapply power. If
fault returns upon power-up, replace EOC.
4. Disconnect power; verify flat cable connections (P6 or P12).
1. Press CLEAR key.
2. Check wiring in probe circuit for possible open condition.
Check RTD resistance at room temperature (compare to
probe resistance chart). If resistance does not match the
chart, replace the RTD sensor probe.
3. Let the oven cool down and restart the function
1. Press CLEAR key.
2. If CLEAR key does not eliminate problem, turn off power for
30 seconds, then turn on power.
3. Check wiring of Lock Motor, and Lock Switch and Door
Switch circuits.
4. Unplug P5, apply power (L1) directly to the Lock Motor, if the
motor does not rotate, replace Lock Motor Assembly. Plug
P5.
5. Check Lock Switch A for proper operation (do they open and
close, check with ohmmeter). The Lock Motor may be
powered as in above step to open and close Lock Switch. If
the Lock Switch is defective, replace Motor Lock Assembly.
6. If all above steps fail to correct situation, replace control.

The fan blade is mounted in the rear of the unit and has a "D" shaped mounting hole. Only minimum clearance exists
between the oven back, fan blade, and fan shroud. Be careful not to bend blade when removing or installing.
Access to the fan blade is gained by removing the fan shroud, held in place by three screws, from the inside of the oven.
The fan blade is held in place with a hex nut that has left handed threads. When removing this nut, gently hold the
fan blade, and turn the nut clockwise. If one of the blades becomes deformed, it may be bent back into shape using
a flat surface as a reference.
A flat washer is located on the motor shaft between the snap ring on the shaft and the fan blade.
NOTE: If the fan blade is bent and motor vibrations increase, the noise made by the fan will be greater.
MOUNTING PLATE OVEN
The fan motor on the rear of the unit is mounted to the main back (with three screws). There is a mounting plate held
in place between the main back (with 2 screws) and the rear oven wall (with 2 screws). Should it be necessary to replace
the oven cavity, you must remove the 2 screws located inside the unit at the rear of the oven cavity.
FAN MOTOR
The 120 volt fan motor is located on the outside of the rear of the oven.

FAN RELAY
The fan motor runs continuously while in the speed bake mode unless the door is opened. If the fan does not operate,
check the following:
• Display illuminated on the electronic control.
• Voltage output between terminals P5-3 and Neutral.
• 120 Volts available at fan motor.
• Fan motor coil resistance 15.0 ohms ± 10%.
• Door/light switch.
DOOR LOCK MECHANISM
The appliance is equipped with an electronic oven control
and has an auto locking door latch feature. When the self
clean cycle is programmed, the door is locked by a motor
operated latch system. The interior of oven doesn't need to
heat up to 500°F/260°C before the door locks. However, until
the temperature inside oven reaches 500°F/260°C, the selfclean program can be canceled and door will unlock
immediately. After oven reaches temperatures over 500°F/
260°C, the door will not unlock until temperature drops
below 500°F/260°C.
If a problem appears and the door stays locked it is possible
for the servicer to unlock the door without removing the
appliance from its place. Follow the steps below:
1. Trip the circuit breaker to OFF position.
2. Remove the 2 screws, which are fixing the oven door
latch, located between the control panel and the oven
door.
3. When the screws are removed it is possible to unlock the
latch with a flat screwdriver, or one of the tools supplied
with the wall oven which are used to take off the oven
from the cabinet. Insert the tool tip through the slot on top
of the oven door. During this step it's important to take
care to not damage the appliance.
4. As soon as the latch is in the unlock position, you can
open the door.
5. Replace the motor latch:
1. To have access to the door latch assembly, remove the 3 screws under the control panel which are fixing it.
2. Remove the access plate located on the upper air channel by removing the screw.
3. Replace the motor latch by a new one and reassemble in reverse order.
