How do I replace the light bulbs that light up the surface under the microwave
For model number LMV1813ST
PartSelect logo
Hi Don, Thank you for your question. Before replacing the light bulbs, please unplug the microwave from the electrical outlet. To remove and install a light bulb under the microwave, you will first need to remove the reflector cover. Unthread the screws securing it and then unthread the light bulb from the socket. Install the new light bulb and reinstall the reflector. Then plug the microwave back in. If you have any questions, please let us know. We are open 7 days a week. We look forward to hearing from you!

My microwave keeps showing power 100 number and will not work.
For model number LMV1813ST
PartSelect logo
Hello Donald, thank you reaching out. The power 100 indicates that the microwave is currently on 100% power. You can change that by pressing the power button and change into the desired power level. If the keypad is not working, keypad or the control board might be faulty. We would recommend replacing the control board, part number PS3534000. If you require assistance to place an order, please contact customer service. We hope that helps!

One of the switches in a component that door activates when shut.
I replaced the whole component with all three switches in it even though only one switch was bad . Taking out one switch out of the holder unit would probably have damaged the unit that was holding the switches. Easy install and it works great again .

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.
