This one has an internal fuse, bottom TCO, and cavity TCO, either of which could be open and interrupting power.

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or near the internal cooling fan or on the floor of the oven behind the control panel or between the door switches.

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

When checking TCOs thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

The TCOs you need to be concerned usually with have black wires. You can ignore the ones with blue / violet wires in this case.

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 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.

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.

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.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There is also a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

My ge microwave just stopped working


Do you have power to the outlet? If so and you are mechanically inclined, you can unplug the microwave, remove the cover and there should be a fuse located on or near the circuit board close to where the power cord comes in. Test that fuse using a digital multi meter. That is usually where the malfunction takes place. If it is good then the main board has probably failed and may be cheaper to just replace the microwave.

No power checked outlet and power is on


HELLO.

This is the way out of the problem.

The outlet is on power,the power problem is from the microwave.

check on the back of the microvave to locate the fuse that control the supply of power to the microvave.

Change the fuse because it is unable to control power supply.

Then plug the microwave to the outlet.

Thanks .

GE Microwave - Power Cord Appears to be Dead


Most microwave ovens are equipped with an internal fuse. This is typically located where the power cord enters the cabinet. The cabinet will have to be opened to verify the fuse.

The magnetron is not directly attached to the power source, it has to be stepped up in voltage significantly, either through a transformer or inverter.

It is usually best to have professional tech check the fuse for operation. Most shops will do this for a small fee if you drop the unit off yourself.

Ge microwave model #JVM1540SM1SS


Check the internal fuse. Unplug it, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. It looks like a regular fuse but is white instead of clear glass because microwave fuses are special. You'll have to measure it with a meter as a result and be sure to replace it with the same kind. (try finding them at radio shack) Hopefully there isn't something more serious also.

Microwave stopped working


Generally, you get something unless the fuse inside is blown. There is generally a fuse inside the unit when you remove the button package. First, make sure that the outlet you have is good. Plug something else into it and see that it works.
