Microwave shuts down

6 posts in this topic

Whirlpool MH1160XSY-0 shuts off intermittently.  Varied run time, power setting, etc.  If unplugged and re-plugged, it works again until next random shutdown.  Nothing on display when it quits, no light inside when door opened......DEAD!

 

This is newly mounted as a built in with exhaust in re-circulation mode.  Previously worked great since purchase in 2007.

Any help greatly appreciated.

Thanks, John

This makes me suspect a loose main power connection on the control board.  Unplug, open the control panel, and check the main power harness.  There's a tech sheet inside the control panel compartment that identifies the connectors on the control board Part number: AP4319365

will do....someone also suggested the internal fuse/assembly.

could door switch cause symptom of complete power loss?

The fuse is non-resettable.

I don't think a flakey door switch would kill voltage to the control board, just the HV side.

I agree I think the door switches are fine and the fuse is too since if it blows it won't fix itself. If there isn't a bad connection somewhere I'm gonna bet you have a control board problem. Check the outlet on the wall too for a loose connection where the house wire attaches on the back. If the connection opens up, just by you unplugging it and plugging it back in you may be disturbing it enough to make it work again. Either that or the outlet is bad.
