Microwave would not rotate or heat up food.
After watching a few youtube videos, I used a phillips SD to take controll pannel off to access the switches that sense when microwave door is closed. Swapped out all 3 switched and mocrowave works like new. $20 fix (shipping included)

Microwave would not power up.
Fun and easy fix for my kids.

The countdown timer was working but no "cooking" happening. Did not hear the familiar sound of the heating part working.

Determined it might be some simple switches for under $15 dollars. Bought one of each. They allow the microwave to turn on/activate by signaling that the door is properly latched. My wife noticed that it was failing and then failed over the course of about a day. Several times where it worked, then did not work. The timer was counting down one time and then when she opened the door the microwave heating component turned on. Guess it had activated the switch as she was opening the door.

Procedure to repair
- Unplug
- Remove two screws on front top - allows you to remove the vent. Realized there was a charcoal filter there that I had never replaced so ordered that after the fix.
- Remove two screws to pull off the front right panel (area where your microwave buttons are) One at the top under the before mentioned vent and one under the microwave on the far right corner.
- Have someone hold the panel because wiring is to short to place it on a ledge while connected or take a picture and remove connections. I simply held it while my daughter undid the micro switches.
- Carefully remove micro switches. There were two "orange" button ones so I chose the top one to replace along with the green button one that I had ordered, so I simply pulled an orange from the bottom and a green from the top latch area. You may have remove the part that holds the switches since it was a little tough with the wires in the way and not knowing how the switches stay put.
- plug in new switches and place in the brackets that hold them in place
- reverse everything you did.
Viola - a working microwave vs purchasing a brand new for several hundred dollars or having to call in a technician.I love that my young kids did this project with me and we actually got it running. Don't like to have to throw away more items at the landfill.

Microwave would not heat anything and turntable no longer turned.
I decided the door switch was the problem because 2 problems happened at the same time. I removed the 4 screws for the top outside cover and the 1 screw that held the control board. After removing the control board screw, I lifted it up and removed it. This gave me access to the 3 door switches. I then removed the 2 screws that held the plastic piece that holds the switches. This made it easier then to replace the switches.

When the MW door was opened a fan would start running. Close the door the fan would go off.
Removed the MW from the wall. Took the top screws off the air vent. Then removed the two screws holding on the display. I then moved the display to its side and it revealed the micro switches. I removed the plug in leads from the micro switch one at a time. I did this with all three micro switches only one at a time. I reinstalled everything and plugged it in. No more fans starting when the door is opened.

We have to slam the microwave door several times to get it to go on, is part(ps3529294) or 66owlk00ld which replaces 3b73362e the correct part? I feel handy to try fixing it, thanks
For model number LG LMV2015SW

Hello John, thank you for your question. If the door needs to be slammed a few times to get the unit to turn on the issue is most likely with the door switches. There are three switches that are in the unit, and we recommend you replace all three. You will want to replace 2 of part number 6600W1K001D and 1 of part number 3B73361E. Good luck with your repair!

This morning when I opened the door to the LG microwave, the platter started turning. The microwave did not turn on, just the platter. When you close the door, it stops. The microwave works fine otherwise. I assume one of the three interlock switches stopped functioning. Can you help? Also can I replace the switches without having to installed in place? Thanks much !!
For model number LMV1683ST

Hi Peter, Thank you for the question. I suggest testing the switches to check for continuity with a multi meter. You do not have to remove the unit from the mount to get access to the switches but it will be easier. Hope this helps!

I owned this microwave one month and had a repair man under warranty repair. What’s happening is the timer works but no heat, no glass rotation and no fan comes on. The light inside works. The light and exhaust fan works. Please advise. Ty

Hi Doug, Thank you for your question. If your microwave is not producing heat and the glass does not rotate, the door switches may be malfunctioning and they will need to be replaced. The part numbers listed under your model number for the switches are PS3522738 and PS3522736. If you would like to place an order for them, you may order them either online or by calling our customer service line and anyone will be happy to assist you. We hope this helps!
