SOURCE: Microwave does not heat

Just had the same experience with the identical model. Removed the cover (a challenge because of the security screws), revealing valuable troubleshooting directions intended for an experienced technician. However, I think the info is well within the reach of a typical DIY person, does not require any dangerous power-on conditions. However, make sure that you discharge the HV capacitor before trouble shooting. In my case, it appears that the HV diode is open, have ordered a replacement on the internet for $3.18, easy to replace. Hope it works. Good luck.

SOURCE: LG LMVM1935SB Microwave won't heat anymore!

With these symptoms, I would suspect you have a bad magnetron.

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.

Some manufacturers will send you the magnetron to do it yourself. If nothing else, you can save about $75 by taking it to the shop yourself.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

SOURCE: Plate does not rotate freely and make noice

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.

There should also 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.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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

SOURCE: LG Microwave does not heat food

est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

The glass plate of the oven is not rotating, what should I do.is it safe to run the oven like this.


The motor driving the turntable is faulty, using the oven like this will not damage the oven, the food will not be cooked evenly though. Open the door and rotate the food occasionally to ensure allround cooking, close door and continue cooking.

My Kenmore Microwave slowly heats but mostly the dishes vs. the food. By the time the food is warm enough, the plate or mug is practically baking. The microwave is only 4 years old, so I can&#39


Sounds like you don't have proper microwave-compatible plates or mugs. Must have lead in them, or in the paint (!?!) Try a plastic plate or even a paper plate. I can't think of anything that would make the microwave oven do that, UNLESS it's a microwave/convection oven, in which case, the convection heater must be coming on whenever you are trying to just use the microwave function.

Have a shop look at this---there usually is a recessed safety switch inside the jam that will prevent the unit from working with door open--sounds like the problem may be with it.

My microwave turntable has stopped turning. Has this been an issue with other LG microwaves? My microwave is just over a year old. Please advise. Thank you. Nancy Pappas


It is only an issue with all manufacturers when the plate is turned when checking the food as it will strip the plastic teeth is the tiny gear box.
The motors are fairly inexpensive to replace.

Microwave doesnot heat anything


6 years is a good run for a microwave to keep working
as it is basically a high frequency radio transmitter, take it in for a proper diagnosis and a quote
mostly after 6 years there may be a shortage of parts available for repair so keep in mind that it may be cheaper to junk it and get a later model
