My 2 year old Whirlpool Combo Oven/Microwave is resetting itself at the end of cooking or microwaving cycles. Happens typically when the oven finishes it’s cool down cycle or the microwave beeps to tell you the cooking timer has finished. Screen resets to 12:00 and shows PF (Power Fail I assume) in the display.
Had a service guy out a few weeks ago, he found bad wiring connections behind the oven (wirenuts melted) This was totally replaced and re-wired by a pro electrician as we thought this was the cause of the PF error codes all the time, but possibly that has caused some instability somewhere else in the device…
If there isn’t a bad connection in the main wiring nor in the wiring inside the appliance leading to the control, there could be a problem in the electronic control board itself. I don’t know if the previous condition could cause any other problems but may definitely be a possibility with these electronic controls. :rolleyes:
The microwave may be causing a power surge when it stops heating that may be interfering with the other control? A loose connection somewhere in the wiring might cause that but I’ve never heard of your exact complaint before.
You might need to call in a professional to try to track it down. If you do I would suggest a Whirlpool factory service depot (see the following link) as they should be most familiar with the product and should know of any particular problem areas to look into first.
