Craig for Model Number PVM1870SM3SS Microwave does not power up. I checked outlet for main power with meter and it's good. I checked both of the line fuses for continuity and they are both good. I still have unit mounted under cabinet. How and where do check the thermal fuse and thermal protector? Or what else can I try? The problem began with simply setting a cook time and microwave would run for a few short seconds and then loose all power.It would return with in a few seconds and a message would appear "power interrupted during cook time please reset" I'm not sure where to go to from here.
Answer Hello Craig. Check all connections inside the microwave and see if any are loose or bad. If not, then you will need to order and replace the smart board WB27X11068 in the unit. Read More... Answered by AppliancePartsPros.com | Wednesday, January 21, 2015
