If you can program the time but it will not start cooking when you press the "Start" pad, you probably have a bad door switch or door switch mount.

If the oven has no display and will not respond, it is "dead" ands it may have a blown fuse or a blown magnetron thermal cutout (TCO) or thermostat or a blown oven cavity TCO or thermostat.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Accessing some components (especially an oven cavity TCO / thermostat) for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

No power to clock or microwave. Have checked breakers.

The main fuse in the microwave oven has probably blown, caused by a defective door.

No Power. Receptacle good. 120VAC at receptacle. Woke up to dark display.

Normally, if it was running and the fuse blows, it is then an electrical/electronic fault. If you simply woke up to the fuse being blown, then very possible it is only the fuse from a cocoaroach or the like.having gone onto a live part of the circuit. Pull the plug out and remove outer cover. Locate the fuse on the board where the power wire comes in and replace for the same value (normally 12 amps).Switch on and try with water in the microwave. Please stand clear when testing as the power is huge in the system. If it blows again, really, get a technician that knows what to look for when trouble shooting. 50% of the time it is the capacitor and HVdiode. Other 50%of the time it is the magnatron. Careful testing can ensure the right part first time. Microwave is one of the most dangerous appliances next to a tv set that i have found.

Power receptacle ok. All functions not working.Dead-internal fuse? jvm1790wk01

Sounds like the fuse. I recently replaced it. Remove the grill (look on top of your microwave for two screws) and you'll see the fuse to the right side of the microwave. You can get the fuse at Home Depot.

Microwave went dead


If your microwave oven doesn't seem to work at all, check these: Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.

Please do rate the solution as FixYa and revert for further assistance.

Microwave has no power

1st try to un-plug and then re-plug after a few minutes to reset... if that does not work, then your internal ceramic fuse is probably blown. You can get one at radio shack for $3.... Always start though by checking to make sure the breaker for the receptacle that the unit is plugged into is still set.

GE Spacemaker 2.0 Microwave just died!

If you're getting power at the outlet, the most common problems causing a "dead" condition are a bad thermostat (or thermal cutout / thermal fuse) on or near the magnetron, a blown internal fuse, or a problem on the control circuit board. I would suspect the thermal cutout / thermal fuse in this case. You can find helpful exploded view diagrams and order parts by entering your model number here: If it seems to be a problem on your control board, we repair these for $39.95 nationwide in most cases. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: If you need more help, feel free to follow up here, but please include your model number (e.g. JVM1190, etc.) I appreciate your thoughtful rating of my answer.
