Answer Hello James. Based on the information you provided, it sounds like the control board is bad and will need to be replaced on the unit.

Answer Hello Joe, Since the fan, turntable and light are all controlled by the main power control module assembly WB27X10382 and there is nothing else that could fail that will allow the unit to continue heating, the main power control module assembly has to be bad. Do not use the unit in this state because the fan that kicks off is the fan that cools the magnetron and without it running, the magnetron will overheat and fail.

Answer Julie, You could probably do this replacement yourself, but you have to be really, extremely careful. You'll be working inside the control panel area, near extremely "High Voltage" transformers,diodes, and wiring. Once you unplug the power cord and remove the upper vent grille and screw holding the panel in place, you can allow it to drop open, label and unplug all the wire connectors, remove the control board and reverse the procedure. Thanks and Good Luck
