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.

Microwave Timer would count down, but unit would not heat. Turntable not turning.
Replaced entire door latch assembly with the three micro switches. Easier to replace entire latch assembly as individual switches do not remove easily from latch assembly. Had trouble removing front panel assembly. Parts ordered solved this problem.

Microwave fan would come on when door open. Timer and unit would not switch on.
I looked up my problem on the internet and found a very helpful video. Microwave on video was different brand but the internals and methods were very much the same. The video made it simple and easy to fix. Found the replacement switch on the LG parts site and ordered. Two different switch types. One with red switch, the other green. Part was $7.28. Saved a bundle in service costs. Here is the repair video.

When I shut the microwave door and select how long I need to heat something up and then press start, the round glass on the bottom of the microwave does not rotate. The microwave is on but no rotation. Therefore, it is not heating.
For model number MV1526W

Hello Carol, thank you for contacting us. We have researched the model and would recommend checking the micro switch, part number PS3598700. It monitors the door latch position and communicates to the electronic control board whether the latch is open or closed. A faulty switch might not detect the door position properly. If the issue remains, the problem might be with the turntable shaft, part number PS3522924, or the turntable motor, part number PS3529213. We would suggest making sure the turntable is properly sitting on the shaft. We hope this helps, good luck with this repair!
