Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

SOURCE: Stops cooking prematurely

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

SOURCE: Sharp model R-1870 Carosel quits cooking at 59 seconds

This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample photo for a typical damper assembly.

We have the applicable service manuals for these models and have uploaded it to our site here and here to help you. You will need the free Adobe Reader to view or print it.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

SOURCE: GE Microwave turns itself off after a few seconds

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again. If that doesn't work, leave it unplugged for about 5 minutes.

Otherwise, I would suspect a "noisy" failing magnetron.

NOISY MAGNETRON TEST (c) 2009 William E. Miller [email protected]

One way to test it is to do the following:

1. Unplug the microwave or turn off its breaker.
2. Open the door, then detach the control panel as shown in the video at http://www.microwavedisplay.com and swing it down, but without disconnecting the wires. If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.
3. Plug the microwave back in.
4. Make sure neither you nor anyone else reaches in behind the control panel. There will exposed high-voltage connections.
5. Put a few cups worth of water in a microwave-safe container and place it inside the microwave.

6. Shut the door.
7. Run the microwave for about 1 minute or so on full power. (Time Cook > 1 > 0 > 0 > Start, e.g.)
8. If it does not fail, try it several more times.
9. When the water boils, change the water and try again.


NOTE:
If your model does not have a door handle, you will need to unplug the oven and reattach the control panel to be able to open the door.


If it still does not fail, I would recommend that you put it all back together and keep using it until it fails more consistently, then repeat this test.

While a microwave should never be left running unattended under any circumstances (as your owner's manual will tell you) it's even more important when one is exhibiting a failure or any odd behavior. So play it safe and stay with it while it's running!

If you or someone you know want to replace the magnetron yourself, you will need 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.

You can download GE owner's manuals and installation instructions here.

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.

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

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Sometimes they will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.

Can I disable the express quick cook feature of Emerson MW8997B?


That feature may or may not be on your microwave oven. GE has quick cook options of 30 and 60 seconds (not a keypad selection).

DANGER WARNING! Potential Hazard if your microwave was working and now doesn't...


If you have this model microwave and it was working fine, then one day it stopped heating items placed inside there are a handful of different issues that could be the problem. In my case it was intermittent, over a period of a few days it would sometimes work (heat) and sometimes not. NO MATTER if this is what your's is doing or if it stopped heating all together. If you decide to let it dry out, or not use it for a while to see if it was a one time occurrence, or whatever the reason, the first time you put something in and probably for the next 10 times at least (this assumes it starts to work again), make sure you are right there with it while it is cooking. Don't assume you can put something in, go do something and come back when the timer is beeping. There is a chance (as this happened to me) that your food inside will CATCH FIRE! Normal food item placed inside, no metal, nothing different than the numerous times before when this had been cooked but when we smelled smoke we came running. Fortunately it started and finished inside the microwave but that's not a guarantee, it could spread. Play it safe. Never had a problem like this before and never heard of a microwave cooking something until it caught on fire (especially since the time entered for the cook was 30 seconds) but it did.

Powers off immediately after starting


My immediate reaction would be to cut your losses and buy a new unit as sooner or later you will run into a part that is no longer available.

Stops working after 20 seconds


The magnetron is over heating causing the thermal fuse to open to cut power, the only option is replace the part, but keep in mind it is the most expensive item to install.

I think you've put up with enough hassle from this unit and should get another one. Intermittant flakey problems are hard (read expensive) to fix.

WHEN PRESSING COOK TIME OVEN CLICKS ON FOR ONE SECOND AND RESETS CLOCK


Please try on some other power point as if there is loose contact or sparking in point which cause to switch off as soon as you start because of heavy current drawn by oven and clock also resets. If not solved even then must have some short circuit or over loading in timer circuit or magnetron. in this case you have to call for a service engineer.
