SERVICE DATA SHEET
GAS RANGES WITH 5XX OVEN CONTROLS
NOTICE: This service data sheet is intended for use by persons having electrical and mechanical training and a level of knowledge of these subjects generally considered acceptable in the appliance repair trade. The manufacturer cannot be responsible, nor assume any liability, for injury or damage of any kind arising from the use of this data sheet.
IMPORTANT NOTE: This unit includes an EOC (electronic oven control). This board is not field-repairable.
Verify the unit has the proper oven relay board, oven user interface board, and touch panel based on the model number and parts catalog.
Safe Servicing Practices
To avoid the possibility of personal injury and/or property damage, it is important that safe servicing practices be observed. The following are some, but not all, examples of safe practices.
1.Do not attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory manner.
2.Before servicing or moving an appliance, remove power cord from electric outlet, trip circuit breaker to
Off, or remove fuse.
3.Never interfere with the proper installation of any safety device.
4.Use only replacement parts specified for this appliance. Substitutions may not comply with safety standards set for home appliances.
5.Grounding: The standard color coding for safety ground wires is green or green with yellow stripes. Ground leads are not to be used as current carrying conductors. It is extremely important that the service technician reestablish all safety grounds prior to completion of service. Failure to do so will create a potential hazard.
6.Prior to returning the product to service, ensure that:
•All electric connections are correct and secure.
•All electrical leads are properly dressed and secured away from sharp edges, high-temperature components, and moving parts.
•All uninsulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal parts and panels.
•All safety grounds (both internal and external) are correctly and securely reassembled.
•All panels are properly and securely reassembled.
Temperature Adjustment
Refer to the Use & Care Manual for directions on how to adjust the oven temperatures.

1. |
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. |

F33 |
Meat probe temperature sensor shorted or |
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 |
|
|
too hot |
|
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. |
|

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). |
|
|
oven control does not see the Motor Door |
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, |
|
|
Lock running. |
|
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. |
|
|
|
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 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 Mo- |
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 |
|
|
tor Door Lock does not stop running or the |
|
controlling it is stuck closed) replace the oven relay board. |
|
|
Lock Switch sends an invalid signal. |
2. |
If the motor is not always running replace the Motor Lock Assembly. |
|
F96 |
The oven door has been detected open |

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 |
|
|
during a Self Clean cycle. |
|
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. |
