Hal for Model Number JVM1750SP2SS The microwave randomly goes dead even when not being used. (By dead, I mean everything... the display, light inside when door open, control panel buttons,etc). It likewise randomly turns back on after a few minutes or hours. I checked the power source at the plug and it is OK. Would the fuse (thermoprotector) possibly cause this random on/off symptom or would it always off after the first time it is blown? I thought I would ask first to possibly eliminate it as a possible suspect before taking the unit apart to bench-test the fuse in case it cannot possibly randomly close/open the circuit.
Answer Hello Hal, this may be a control board problem but first, take the microwave down and remove the outer case, check for a loose connection at the main 20 amp/fuse holder and the wiring connections at the cavity and magnetron thermostats.
