Microwave shuts off requiring the clock to be reset when using the
popcorn setting,now it does it most of the time.
a couple of times it gave an F-4 problem.
F-4 replace moisture sensor. Purchased the part from partselect.
Problem still persists.
It will heat water with no problem.

It could be a problem in the popcorn circuit in the board.

What is the part number of the sensor you replaced?
