CAUTION:
DISCONNECT POWER BEFORE SERVICING UNIT.
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS.
WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION.
VERIFY PROPER OPERATION AFTER SERVICING.
ATTENTION:
DÉBRANCHEZ L'APPAREIL AVANT DE PROCÉDER À LA RÉPARATION.
IDENTIFIEZ TOUS LES FILS AVANT DE LES DÉBRANCHER LORSQUE VOUS PROCÉDEZ À UNE RÉPARATION.
UNE ERREUR DE FILAGE PEUT CAUSER UN FONCTIONNEMENT INADÉQUAT ET/OU UNE SITUATION DANGEREUSE.
VÉRIFIEZ QUE L'APPAREIL FONCTIONNE CORRECTEMENT APRÈS LA RÉPARATION.

Code
Description of Error Code Suggested Corrective Action
F46 Cooling fan speed too high 1. Check for mechanical obstruction in the air path.
2. Replace cooling fan.
3. Replace oven control.
F50 A/D Out of Range: the oven relay
board is unable to read the status of
the switches (door, MDL)
1. Check to ensure that the connections between the door switch, MDL and temp probes are properly connected. This includes all
splices and junctions.
2. If the above step failed to correct the problem, replace the oven relay board.
F90 Motor Door Lock mechanism failure.
The oven control does not see the
Motor Door Lock running.
1. Disconnect power to the unit, wait 30 seconds, then reapply power. Try again to make the door lock or unlock (ex: initiate a
Lockout or a Clean cycle).
2. Check if the Lock Motor is running or not. If it is not running, test the wiring between the Lock Motor and the oven relay board.
If the wiring is good, check if there is 120VAC at the motor when it is expected to run to see if the failure originates from a bad
motor (120VAC present but not turning) or a problem with the relay board (J20 pin 10 on the oven relay board is the output to
the Lock Motor). The Lock Motor can also be tested by applying 120VAC directly to the motor (unplug it from the relay board
rst). If the Lock Motor does not run when 120VAC is applied replace the Lock Motor Assembly. If it is the relay board that does
not provide 120VAC to the Lock Motor replace the oven relay board.
3. If the Lock Motor is running but the oven control cannot nd the locked or unlocked position (ex: motor turns continuously until
F90 fault code is generated) the Lock Switch needs to be veried. Check wiring between Lock Switch and oven relay board.
Verify with ohmmeter if the switch makes contact properly (verify continuity with ohmmeter when the switch is pressed). If the
Lock Switch is defective replace the Motor Lock Assembly.
4. If all above steps failed to correct the situation, replace the oven relay board.
F95 Motor Door Lock mechanism failure.
The Motor Door Lock does not stop
running or the Lock Switch sends an
invalid signal.
1. The problem can be caused by a faulty Lock Switch or by a defective oven relay board. If the Motor Door Lock is always run-
ning (as if the relay controlling it is stuck closed) replace the oven relay board.
2. If the motor is not always running replace the Motor Lock Assembly.
F96 The oven door has been detected
open during a Self Clean cycle.
1. This error occurs if the door switch has lost its contact during a Self Clean cycle. Make sure the oven door closes well and fully
presses on the door switch plunger when the door is locked, and no one attempted to pull on the oven door during the Self
Clean cycle.
2. Test continuity of wiring between the door switch and the oven relay board, make sure the door switch is well connected. With
an ohmmeter, verify the switch is closed when the plunger is pressed. If the door switch is found to be defective replace the door
switch.
3. If the switch and wiring are good and the problem persists, replace the oven relay board.
F97 MDL invalid state. Relay board (OVC)
sensed the motor door lock in a state it
should not be in according to the user
interface board.
1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault persists, replace motor door lock.
3. If fault persists, replace the oven relay board.
