Remove the cover, find the fuse on the floor of the device near where the cord enters, check it - unplugged, OF COURSE. Do not touch the silver can - LETHAL! Use a contunity checker to check the fuse. Find a replacement at the hardware store or at an appliance parts supply. Take the fuse with you.

I hope this helps you.

We installed a GE Spacemaker Microwave. I put some potatoes in and the microwave was working, suddenly it went off. No light nothing, it just went completely dead. Came back ON after 15 mins,started...


The main fuse may be intermittent, causing complete power failure, the other possibility is a defective door switch not operating properly, or loose plug in the power feed, I suggest a technician to take closer look at the system because this could prove tricky to find the culprit.

GE JVM1430 Spacemaker is dead. Completely.


See my microwave oven safety file here.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor. How to test a high-voltage capacitor.

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount. My door switch help file.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

If the fuse is easy to twist with your fingertips while it's in the holder, it's too loose.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

Microwave completely dead


A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open. Then when it cools, it closes the circuit and allows power through again.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

Dead? You mean no power, no lights, no beeps, nothing?

It's most likely a blown thermostat / thermal cutout on the magentron, based on your info.

But if you can post the model number I may be able to steer you better.
