A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille 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.

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.

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

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 should also be 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.

If not, please reply back with your brand and model number so we can help you better.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Microwave was beeping a single beep once in awhile now nothing happens but the clock still works

A lot of the time when that happens the touch pad is bad and may have a colappsed air pocket on a pad. ( it makes the unit think you are pushing a pad ) The only way to fix it is to replace it (the touch panel) . Did you see any numbers coming up in the display. Like if the 3 pad was bad and making it beep it may have been showing a 3 in the display,. Always possible it could be a bad main board. But most commonly I have found it to be the touch panel. Try to unplug it and then plug it back in and try to set the clock. when you do, try each number pad and see if they all work. See if any feel different.

Microwave started beeping while unplugged

If it beeps for just a few seconds after being unplugged from the wall, that's not a problem.

It's likely just the software or hardware feature utilizing a "sanity timer" to alert you when the oven loses line power. It's similar to a freezer alarm or sump pump alarm.

If this doesn't seem to answer your question or address your situation, please e-mail me and remind me of your symptoms and include your full model number as shown on the label.

Microwave started beeping with nothing in it now it says SE or 5E

These issues are usally due to a defective touchpad or control board. Troubleshooting would require disconnecting the touchpad ribbon cable from the control board to see if that made the problem go away.

Whirlpool Microwave Hood Combination MH3184XPS-0 (October 2004), for no reason at all, this morning keeps beeping and running the power setting down from 10 to 1, and just keeps doing it in rapid sequence....

Ours just started doing this exact same thing this past Friday - 12/11/09. What's going on? The cook power just starts beeping all by itself and going from 10 down to 1 over and over again. It may stop momentarily, but then starts again within a minute or so - it's constant until we unplug it. We plug it back in and within a few minutes it starts doing it again. What gives?

Power outage now microwave won't work

Most likely blew internal fuse. Pull the top/side cover off and check the line fuse. It should be behind the control panel in that area.

GE xl 1800 beep

The first thing to try is a "hard reset". Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

From what you have described, it appears that the microwave oven works fine, except that the beeper doesn't work like it used to.

This could be caused by a couple of things.

First, there is typically a piezo electric speaker that creates the "beeping" sound. It's possible that this part has failed. It's a mechanical device and can break. This part is relatively inexpensive.

The piezo speaker is controlled by the microprocessor board. It's possible that there is a problem with one of the output lines from the microprocessor that is tied to the speaker.

One way to determine which part is defective, is to try connecting another speaker in parallel across the original speaker, or remove the original and try the replacement (least expensive method).

If there still is no sound, then I would suspect the problem is on the microprocessor board. (most expensive method).

If I can be of further assistance to you, please let me know.

Good Luck!
