If fault returns upon power-up replace the touch panel. The oven user interface board is incorrectly configured. Oven temperature runaway: the cavity temperature has been detected in excess of the maximum safe operating temperature. Stuck key: a key has been detected has pressed continuously for 30 seconds or more. Keyboard configuration alarm: the oven user interface board received from the touch panel a key code that does not match the key map. Data written to non-volatile memory has failed verification Keyboard error The oven user interface board is unable to configure the touch panel. Oven relay board failure (wiggler) The oven user interface board is unable to configure the oven relay board Communication failure between the oven user interface board and the oven relay board Communication failure between the oven user interface board and the glass touch panel The communication between the over user interface and the oven relay board cannot be initiated. The communication between the over user interface and the touch panel cannot be initiated. Open oven temperature sensor (RTD) Shorted oven temperature probe (RTD) Meat probe temperature sensor shorted or too hot Cooling fan speed too low. Replace the oven user interface board. Make sure you install the latest revision available for this model. 1. If oven is overheating, disconnect power. Check oven temperature probe (RTD) and replace if necessary. 2. If the oven temperature probe is good and if oven continues to overheat when power is reapplied, replace the oven relay board. 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. 1. Verify the unit has the proper oven user interface board and touch panel, based on the model number and parts catalog. 2. Replace the oven user interface board. 3. If the problem persists replace the touch panel. Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up replace the oven user interface. Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up replace the touch panel. 1. Disconnect power to the unit, wait 30 seconds, then reapply power. 2. If fault returns, verify harness going to I2C1 or I2C2 connector of the touch panel. 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 oven user interface. 5. If fault persists, replace the touch panel. Replace the oven relay board. 1. Disconnect power to the unit, wait 30 seconds, then reapply power. 2. If fault returns, verify connection between the oven user interface board (MACS1 or MACS2 connector) and the oven relay board (connector J3 or J4). 3. Verify the unit has the proper oven user interface board and oven relay board, based on the model number and parts catalog. 4. If fault persists, replace oven user interface board. 5. If fault persists, replace the relay board. 1. Disconnect power, wait 30 seconds and reapply power. Check if error condition is still there. 2. Test wiring harness between oven user interface board (connector MACS1 or MACS2) and oven relay board (connector J3 or J4). 3. If wiring harness is good replace oven relay board. 4. If the problem persists replace the oven user interface. 1. Disconnect power, wait 30 seconds and reapply power. Check if error condition is still there. 2. Test wiring harness between oven user interface board (connector I2C1 or I2C2) and touch panel (connector I2C1 or I2C2). 3. If wiring harness is good replace touch panel. 4. If the problem persists replace the oven user interface. 1. Disconnect power to the unit, wait 30 seconds, then reapply power. 2. If fault returns, verify connection between the oven user interface board (MACS1 or MACS2 connector) and the oven relay board (connector J3 or J4). 3. Verify the unit has the proper oven user interface board and oven relay board, based on the model number and parts catalog. 4. If fault persists, replace relay board. 5. If fault persists, replace the oven user interface board. 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. 1. Check probe circuit wiring for possible open or short condition. 2. Verify RTD resistance at room temperature (compare to probe resistance chart). If resistance does not match the chart, replace the RTD probe. 3. If the problem persists replace the oven relay board. 1. The error is triggered if the meat probe sees a temperature in excess of 392°F. Make sure the meat probe was not 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. 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. Fault Code F46 F50 F90 F95 F96 Description of Error Code ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS Suggested Corrective Action Cooling fan speed too high. 1. Check for mechanical obstruction in the air path. 2. Replace cooling fan. 3. Replace oven control. A/D Out of Range: the oven relay 1.

Disconnect power to the unit, wait 30 seconds, then reapply power. Try again to make the door lock or unlock The oven control does not see the (ex: initiate a Lockout or a Clean cycle). Motor Door Lock running. 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 test- ed 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. 3. 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 con- tinuity 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. Motor Door Lock mechanism failure. 1. The problem can be caused by a faulty Lock Switch or by a defective oven relay board. If the Motor Door The Motor Door Lock does not stop Lock is always running (as if the relay controlling it is stuck closed) replace the oven relay board. running or the Lock Switch sends an 2. If the motor is not always running replace the Motor Lock Assembly. invalid signal. 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.
