This is usually caused by either a bad door switch, but may instead be a loose door switch mount or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

Bad power diode, bad power capacitor or bad magnetron

Google on 'microwave not heating' and you'll get some sources of information

(If you need more help than this, please reply back with your model number)

It's probably a bad door switch or door switch mount.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

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

If you only need a switch, you can order one from us for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

It may very well have have damaged the turntable motor.

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

On many Sharp models, you have to cut the motor cover off with snips, then use a screw when reassembling it.

SOURCE: my daewoo microwave/toaster blew my breaker upon resetting it and plugging in the microwave it blew again then it tripped my GFI what could be the problem?

Probably a short inside the microwave circuitry.  I had a Daewoo and had nothing but trouble with it.  Main board went out in a year, then again in another year.  Finally went to Home Depot where I bought it and was told that they had nothing but trouble with them and quit selling them.  Now I have a GE Spacemaker.

Yeah pal, you've not gone deep enough yet. You'll find a power wire bare inside the unit, pull it apart and tape that wire up to stop it from grounding out and blowing the fuse.

The switch for the turntable does not disengage anymore. Could be a relais, could be an electronic switch. When opening the door, a second switch, in series with the other one, connected to the turntable motor disengages, stopping the motor. The light is switched on, because you opened the microwave. Perhaps you never noticed this, but it is the normal way that should work.

Microwave won't stop running


there's a ghost in your microwave, call ghost buster. Seriously, the problem is the control panel. (((((the microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. That's more than 30 wall outlets combined.
Replacing electronic parts in a microwave oven can be extremely dangerous.))))))) tank you

It sounds like you may have a shorted cook relay on the control circuit board which can be repaired simply and inexpensively.

The microwave oven needs to be replaced, the magnetron is the most likely problem, there is also a high voltage transformer, capacitor, and diode that are potential issues. But by your description it sounds like more than one part is involved.

Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Check also the turntable . It could be out of it's right place .

WARNING :

1:Don't slam your microwave door because this may cause the fuse to blow and this is the reason of bad door switch problem .
2: A microwave is capable of giving you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

please don't forget to rate .

good luck .

I have a Whirlpool AMW545 built in microwave oven. The turntable continuosly runs with the door shut when the microwave is not in use. The turntable will stop rotating if the door is opened.


the controller for the turntable is shorted out or welded its contact if its a relay. the door has safety switches that turns off the electrical connection to the turntable and magnetron once you open the door. you can trace the switch that runs the turntable. start from the power supply, goes to the door switch then to the controller before it goes to the turntable motor. i'm sure it has an electrical diagram at the inner wall of the cover.
i hope i was able to help.

Unit Electrical Problem


If it blows the fuse as soon as you hit the START button, it's almost certainly a shorted high-voltage capacitor.

If it blows a few seconds after you hit the START button, it's probably the high-voltage transformer. You'll possibly also smell a faint electrical burning smell from the rear vent after you shut if off.

Microwave can be very dangerous so it is best to have it looked by a professional

 

Would appreciate a solved rating for expert advise.
