SOURCE: Problem with Maytag MMV5000BDB Microwave

The problem is almost certainly on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This often can affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on.

If not, please post your brand and model.

It's probably the motor, but possibly the coupler.

One quick check is to remove the turntable and support / roller ring and try to turn the coupler. It should be a little hard to get started, then you should hear a whirring sound, not a clicking or grinding, which would indicate a bad motor.

If the coupler turns loosely with no resistance, then it's probably bad.

Here is my text on replacing couplers, which had steps which are necessary when replacing motors. Note that if yours is a built-in model, ignore the part about turning it on its side *grin*

NOTES ON REPLACING TURNTABLE COUPLERS

Copyright 2007 by William E. Miller - MicrowaveDisplay.com

UNPLUG THE OVEN FROM THE WALL FIRST OR YOU WILL EXPOSE YOURSELF TO LETHAL VOLTAGES!

Note that I am not encouraging you to work on electrical items if you are not qualified, and I assume no liability for any consequences of your decision to do so.

When replacing the turntable coupler on most models, it is necessary to loosen or remove the screws that mount the turntable motor to the bottom of the chassis.

It is usually easier to do this with the microwave oven on its right (heaviest) side because you will need two hands for alignment.

Be sure to put a towel or similar cushion on the work surface to avoid scratching the oven wrapper (oven cover) or the work surface.

It is not necessary to remove the wrapper or the wires from the turntable motor itself, but you may need to remove a small metal duct covering the turntable motor if your oven has one.

It should only be held on by one or two screws.

Although a broken coupler may come out easily or even fall out, the new coupler will not go in without at least loosening the turntable motor.

Look at the hole in the new coupler. You'll notice it has (most do have) a flat side to it. That flat side will line up with the flat side on the motor shaft.

When the old coupler is out and the motor is loose, you can ease the new coupler in the hole with one hand while turning the coupler very slightly back and forth as you gently push the motor toward it. Do not force the part in.

When the coupler has mated properly with the motor, you should feel it go in.

Be sure it's right, or you may break the new coupler or bend the mounting ears of the motor when you attempt to tighten the screws.

Reassemble in reverse order.

SOURCE: JVM2070SH01 shut off intermittently. Now it just won't heat at all.

It's almost certain that your magnetron has failed.

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.

If you or someone you know wants to look into this, we have critical safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

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.

SOURCE: Goldstar Microwave turntable does not work.

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.

You can also do that to attach AC voltmeter leads to the leads of the motor. Then run the microwave to see if it has voltage present.

If so, you have a bad motor.

To order Goldstar / L.G. parts, visit Vance Baldwin Electronics.
You'll probably have to call them to find parts for your model.


(If yours is not an LG/Goldstar, please reply back with your brand and model number so we can help you)

If you don;t see the voltage, then you most likely have a problem with the control panel.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid in about a week with a one-year guarantee.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

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

My microwave turntable stopped turning but the microwave still heats up and works, otherwise.


You didn't say what model microwave you have, but most that I have seen have two separate circuits inside. One operates the magnetron (which makes the microwaves) and the other operates the other things like the turntable or the inside light etc.. It is quite possible that you have a problem in that second circuit. This allows the heating without the turning. To fix this type of problem, if indeed that is the case, requires some skillful trouble shooting inside the microwave which I don't recommend your try unless you are a skilled technician, because of dangerous voltages. Go ahead and post the brand and model number and I can be more specific as to what action to take.

Panasonic NN-A755


It does sound like the magnetron is failing, when it shuts down it is because the thermal fuse is detecting to much heat from the magnetron and shutting it down, I might add this part is the heart of the system, rough cost would be in the area of $100.00 maybe cheaper. Intallation of this part is very tricky and there is the danger of high voltage, I recommend a pro for safety and correct installation.

Turntable has ceased to function when oven is on. Is it dangerous to use like this?


Not dangerous, but your food will not be efficiently or evenly heated. To change the motor do the following:-

There is a panel under the microwave, held on by one or more screws. Remove it and you will see the synchronous motor inside. There should be a plug to disconnect the wires. Remove the motor and fit a new one. Ensure that the microwave is disconnected from the wall outlet before attempting any work on it.

Turntable stopped turning


Some microwaves have a button on the control panel that disables the turntable. Make sure that this button hasn't been pressed.
Next most likely causes are a the stirring (turntable) motor has malfunctioned or possibly a turntable belt is broken or slipping (if equipped). This will involve opening up your microwave (and probably removing it from the wall), diagnosing the problem, ordering the parts, then replacing them.

Remember, while you can do some repairs on your microwave, what you don't know can kill you... even on an unplugged microwave, so make sure you understand the dangers and how to reduce them before you try anything inside a microwave. If you want to do more yourself, let me know and I will point you in the direction of some good resources.

Yes, you can paint over the spots and no, it's not dangerous. I'd let the paint thoroughly dry before using the oven -- it could otherwise cause paint to buckle/ripple/etc.
