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 .

The major plastic frame was broken at the screw hole support. I was sent the wrong part and found out the part I needed was no longer made and would have to buy a new door for $150.
The wrong part was under $20. When I found out I had to replace the whole door for $150. I decided DYI was the way to go. I used JB weld and the door looks and works like a charm. Give plenty of time to cure all water needs to be cured out if exposed to microwaves. No problems so far.
