Question and Answers

Q:

Is my LG microwave model LMVM1945SW that had 3 issues occur at about the same time worth repairing or should I replace it?

A:

The microwave could be making noise if the turn table, the ring assembly or the turn table shaft are not aligned properly. Since the microwave heats, the noise is not necessarily related to the magnetron. If the noise is grinding noise, I recommend that you pull the turn table out and check the ring. Look for a crack or damage on the turn table shaft. The turn table shaft is a part that you can order and replace yourself if it is cracked or apparently damaged. The part number for the turntable shaft is 4370W3A001A. You can order it from the Sears PartsDirect website.

Try shutting the turntable off using that setting on your control to see if the turntable system is making the noise that you are hearing. Here is a link for the owner's manual on your microwave: Owner's Manual . The turntable on/off feature is shown on page 11 of this manual. NOTE: The model number that you indicated in your details (LMVM1945SW) appears to be slightly off. The manual noted above is for model LMVM1935SW.

If the noise stops after you shut off the turn table then this is the apparent cause of your noise. If you are not able to resolve this noise by replacing the shaft and/or properly aligning the ring and turntable then the microwave would need service. The turntable motor is likely making the noise and this would be a component that a technician should replace since it is an internal microwave component. If you can do without the turntable, you can continue to use the microwave by shutting it off. Cooking results may not be as even but the microwave will still heat the food.

You can actually replace the interior oven light by following the procedure on page 29 of your owner's manual. Be sure that you unplug the microwave before accessing this light.

If you are able to resolve these problems in the microwave, then you may not need to replace the microwave or have it serviced. If the microwave still makes a noise even with the turntable motor turned off then I recommend that you have it serviced or replace it. It is normally more economical to replace the microwave rather than to have it serviced. Even though the magnetron is under warranty, this is not the likely failed component since the microwave is still heating. A service call will likely cost at least $150 not including parts.
