Kathy for Model Number ARHSC8750 Getting ready to do some Easter Baking and the F-codes are creating grief! F-3, F-4, F-5. We have experienced F-1 in the past and we have replaced this part multiple times. This is the weak link on this oven, which I really like other then this. Should the test be the same as the F-1 message? Thanks in Advance for your answer.
Answer Hi Kathy. I would use a volt/ohm meter part # MA-DM1 to assist. you in your diagnosis. The F-1 code is the clock membrane (mylar) shorted issue. Unplug the ribbon cable from the control board. If the code continues, you will need to replace the control board AP4041348. If the code is gone, you will replace the membrane switch WP316189B. The F-3 code is a open oven sensor part # WPY0314907. The F-4/5 codes are a door lock situation. The door motor is part # Y0315908.The door lock switch is part # 59002155. Is the door unable to open? Is the door fully closing and allowing the door switch to tell the clock it's position ? Switch part # Y0316882. Thank You. Read More... Answered by AppliancePartsPros.com | Friday, April 6, 2012
