Oven temperature runaway: the cavity 1. temperature has been detected in 2. excess of the maximum safe operating temperature. If oven is overheating, disconnect power. Check oven temperature probe (RTD) and replace if necessary. If the oven temperature probe is good and if oven continues to overheat when power is reapplied, replace the oven relay board. Stuck key: a key has been detected has pressed continuously for 30 seconds or more. 1. If a key was pressed inadvertently for a long time this error code will be displayed. Make sure there is nothing (water, utensils) in contact with the keyboard. The fault code should go away once the key is released and the Stop key is pressed. If the F011 error comes back when a key is pressed it means the error condition is still there. If the F011 error does not come back it means the error condition is gone and the oven can be used. 2. If the fault code cannot be cleared, test the wiring harness between oven user interface board (connector I2C1 or I2C2) and touch panel (connector I2C1 or I2C2). 3. If the fault code cannot be cleared and the wiring is good, the touch panel is most likely defective: replace the touch panel. 4. If changing the touch panel did not fix the problem replace the oven user interface board.

Verify the unit has the proper oven user interface board and oven relay board, based on the model number and parts catalog. If fault persists, replace relay board. If fault persists, replace the oven user interface board. The communication between the over user interface and the touch panel cannot be initiated. 1. Disconnect power to the unit, wait 30 seconds, then reapply power. 2. If fault returns, verify touch panel is connected (verify harness going to I2C1 or I2C2 connector) and is getting power from the oven user interface. 3. Verify the unit has the proper oven user interface board and touch panel, based on the model number and parts catalog. 4. If fault persists, replace the touch panel. 5. If fault persists, replace the oven user interface. Open oven temperature sensor (RTD) 1. 2. Shorted oven temperature probe (RTD) 3. Check probe circuit wiring for possible open or short condition. Verify RTD resistance at room temperature (compare to probe resistance chart). If resistance does not match the chart, replace the RTD probe. If the problem persists replace the oven relay board. Meat probe temperature sensor short- 1. The error is triggered if the meat probe sees a temperature in excess of 392°F. Make sure the meat probe was not ed or too hot used in such way that it could have seen such temperature. If the tip of the probe is not inserted in the meat it will see the cavity temperature, which can be higher than 392°F (depending on the setpoint) and trigger the alarm. 2. When the meat probe is connected to the socket inside the oven cavity, if the meat probe is not fully inserted into the socket it may short the contacts and cause the error. Make sure the probe is inserted as much as it can. 3. Verify meat probe resistance at room temperature. Compare to meat probe resistance chart. If the meat probe does not match the chart, replace it. 4. If the above steps failed to correct the problem, replace the oven relay board. Upper oven cooling fan speed too low 1. Check if the cooling fan blades are blocked. 2. Confirm tachometer harness is connected on fan and on oven control. 3. Replace cooling fan. 4. Replace oven control. Upper oven cooling fan speed too high 1. 2. 3. Check for mechanical obstruction in the air path. Replace cooling fan. Replace oven control.

The oven door has been detected open 1. during a Self Clean cycle. 2. 3. Check if the cooling fan blades are blocked. Confirm tachometer harness is connected on fan and on oven control. Replace cooling fan. Replace oven control. Check for mechanical obstruction in the air path. Replace cooling fan. Replace oven control. Check to ensure that the connections between the door switch, MDL and temp probes are properly connected. This includes all splices and junctions. If the above step failed to correct the problem, replace the oven relay board. 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). 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 first). 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. If the Lock Motor is running but the oven control cannot find the locked or unlocked position (ex: motor turns continuously until F90 fault code is generated) the Lock Switch needs to be verified. 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. If all above steps failed to correct the situation, replace the oven relay board. 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. If the motor is not always running replace the Motor Lock Assembly. 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. 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. If the switch and wiring are good and the problem persists, replace the oven relay board.
