F4/F3 Error Sensor; Turns on automatically and beeps

:mad: For the past three or four months the mocrowave has intermitantly turned itself on, "fresh veggies" would begin cooking. It would end and either the F4 or F3 sensor error would come on and the microwave would beep. Usually in the middle of the night. I was able to hit clear and everything would be fine. That is not the case any more. Now, the machine turns itself back on repeatedly.

I have read through some of the other posts and it looks like the control panel is bad. Do you believe this to be the case?

If you could tell me the part numbers I need to make this fix and any discription would be great.

Best Regards,
John
