Hotpoint microwave 2010.
Got a call that this unit was dead.
Went out and found the control board not illuminated or accepting any input from touchpad.
Checked for current and found current going into microwave up to the board.
Followed instructions on tech sheet went through steps that led me to bad pcb.
Replaced PCB unit worked. Ran it 3 times for a total of about 2 minutes and left.
Customer called back next day and said it was dead again just like before.
Will be going back and checking voltage, fuse, and see if it's the board that's really bad again.
