A clogged air filter can cause your appliance to run inefficiently and possibly alter the taste and smell of your food. This filter is approximately 7.5 inches wide and 5 inches deep. This part is sold separately. No tools are required for this repair, the filter simply slides in and out using the easy-pull tab on the filter.

This is a light bulb and it is a part for your microwave. This bulb uses 30 watts, operates on 125 volts, and is an incandescent lamp.

Part #6600W1K001D
The door switch, often referred to as a primary interlock switch, provides power to the various components in the microwave when the door is in a closed position, and interrupts power when the door is open. This door switch is approximately 1 1/2 inches long, and has 2 metal prongs called terminals that extend from its body. Common symptoms related to a faulty primary door switch include: microwave will not turn/shut off, or the microwave will not heat properly. You can check the switch for continuity using a multi-meter. With the actuator button depressed, you should see continuity between these terminals. If there is no continuity the switch will need to be replaced. NOTE: Before you begin this repair, first make sure your microwave is unplugged, and that your capacitor is discharged. A capacitor stores large amounts of electricity even when your microwave is unplugged.

Ken - For model number LMV1680WW
March 3, 2020
When I turned the microwave on I heard a pop and now it does not heat. The motor sounds a little louder than it did when it was heating. The keypad, timer and turntable work. Is there a fuse or part that can be replaced to make it heat again.
Chris Boyle Profile
Hello Ken, Thank you for the question. There is a Fuse, PartSelect Number: PS3522741 but when it blows there would be no power to the appliance. We suggest testing the High Voltage Diode PartSelect Number PS3528799 with a multi meter to see if it blew/ We hope this helps.

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 prop erly 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.

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.
