How to replace fuse on GE Profile microwave 1.1 cu ft, PEM318M3SS

The power suddenly died on this microwave, model PEM318M3SS, and all the sites have for other microwaves. I believe there’s an access panel inside, looks like something you could open with a flathead screwdriver, but I don’t want to break the piece. None of my searches turn up this model, which is very common. 1.1 cu ft, theoretically countertop, but usually mounted under a cabinet.

Did you try reviewing guidelines for GE microwave ovens in these forums? To the right of your post is an image with a link to disassemble your unit to find the circuit board and any fuse on it.

Yes I did look. Those models have the openings where it doesn’t exist on this model. Alas. Hence why I posted.

Without service manuals or someone knowing more, you're left to try disassembling it.

@Vicky K everything im seeing for profile ge microwaves is saying to take off the front control panel. Be very careful. If it is plugged in now, unplug it and tomorrow open it up. Be careful as there is a capacitor that is most unpleasant to discharge into yourself. Try carefully opening it up, and looking for a fuse. Alot of fuses when they go can be diagnosed by a simple visual inspection.

Hi,

Did you mean GE PEM31SM3SS?

If so, here’s a link showing the location of the fuse in your model microwave oven.

Be safety aware when working in microwave ovens. The HV capacitor can store >6000V DC for months even if the power has been disconnected for this length of time. This amount of voltage can seriously injure you. The HV capacitor needs to be correctly discharged as soon as it can be accessed after the oven’s cover has been removed and before any other repair work is started inside the oven. If you don’t know what you’re doing, then don’t do it! Contact a reputable, professional appliance repair service and ask for a quote.

Also note that fuses blow for a reason. They very seldom fail for no reason. If the fuse is blown in the oven the cause will have to be found. Here’s a link that may help.

There should also be a "mini-manual” (GE p/n 31-40080), i.e. wiring diagram, hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.
