Screen says PF after use and smells hot, what is PF?

I have a GE Microwave Oven WES1450DS1BB.

1. trouble shooting, PF on screen.

2. cancelling causes screen to go black.

PF is power failure. Sounds like some trouble with the main power board.

The PF error code means that either you magnetron is going bad and leaking microwaves, or the control board itself is bad.

I wouldn't touch this with a pole. It's to dangerous to work on. Either call a tech (it's not that expensive a model, or trash it. It would be prudent to just replace it.

I agree. Microwaves can be very dangerous to work on. Not just 120V but thousands of volts. Then there is the RF to worry about if you are not careful.
