Kitchenaid microwave model KHMS155L, starts randomly for 3 minutes with "PAN" flashing on display screen, than locks up with "F-2" message on display screen

"F2" means you have a shorting membrane keypad. The "Pan Heat" key is shorting.

On these models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

You can find helpful exploded view diagrams and order parts by entering your full model number* from the tag on the oven here.
