Wiring Diagram

F050 A/D Out of Range: the oven relay
board is unable to read the status of
the switches (door, MDL)
1. Clear error, cycle Power a couple of times and check if error is back, if so replace Power board.
2. Replace Door switch plunger/s and reseat harness.
3. If error persists check MDL & Harness.
F090 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 (J8 pin 1 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.
F095 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 running (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.
F096 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.
User unable
to enter self-
clean, with all
burners off
Invalid key tone when user tries to
start self-clean without burners turned
on.
1. Check if previous clean was run within the last 4 hours, if so clean should work after 4 hours.
2. Enter FTM and press self-clean button, if “SCC” in the temperature display. Check wiring from
J2 Pin 3 to resettable thermal cutoff switch under the front right burner. Check if the resettable
thermal cutoff switch under the front right burner is closed at ambient temperature, if open
replace it.
3. Lastly if above steps work as expected, replace Power board.
