Do-It-Yourself Stories from Customers like You Light not going on and cover missing.   Jerry J M. • Monona , WI • August 02, 2020

When the new bulb didn't want to go in, I felt around and realized the base of the old bulb was still in there. With some effort I got it out and new bulb in, Light cover fit fine, but did not come with a screw to hold it in. That would have been helpful. Read more

Do-It-Yourself Stories from Customers like You My jenn air microwave developed a loud hum and no longer heated anything   Jared B. • Norfolk , VA • October 04, 2014

I am not an appliance repair man. I am a general surgeon. I went online and researched the problem. The consensus was that my magnetron and diode were the most likely culprits. To replace my microwave with a comparable model would have cost at least $800. The diode and magnetron cost around $170. I watched a few videos on YouTube demonstrating how to do the repair safely and I felt like I could do it. I ordered the parts on a Monday evening and had them Wednesday. The only difficult part of... Read more

  • The door not latching properly

Microwave Door Switch (Interlock Microswitch)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP3405-001034

This door interlock microswitch detects when the microwave door is fully closed and allows the unit to run only under safe conditions. Replacing a worn switch restores reliable starting and consistent operation tied to the door latch.

  • Monitors the door-latch position and completes the safety interlock circuit when the door is closed
  • Helps prevent operation with the door open
  • Common symptoms: microwave won't start or stops when the door is moved; requires pushing/jiggling the door to run
  • Contributes to "runs but no heat" or light/fan behavior that changes as the door is opened/closed
What's included: One door interlock microswitch Install notes:
  • Unplug the microwave before service; internal high-voltage components can retain a dangerous charge
  • Access the switch at the door-latch assembly; transfer wires one at a time to the new switch to maintain correct positions
  • Ensure the actuator aligns with the door latch and that the switch clicks freely when opening/closing the door
  • After reassembly, test with a microwave-safe cup of water to ensure proper operation
Note: Many microwaves use multiple door switches; each is sold individually.

This part fixes the following symptoms
  • No heat

Do-It-Yourself Stories from Customers like You Microwave would not heat had power   Robert W. • Sanford , FL • May 28, 2015

Utilized a YouTube video to isolate the door switches as the issue. These were easily identified following the isolation process and simple testing. I ordered a door switch and secondary switch on Monday and they arrived on Tuesday via FedEx. 15 Minutes to re-install, re-assemble cover and the unit was working fine. A very good experience with parts availability and shipping. Read more

Do-It-Yourself Stories from Customers like You Our lg lmv2031bd otr microwave started making scraping and clunking noises but continued to work fine otherwise   Russell S. • Moultonboro , NH • January 06, 2025

Looked online and found that someone had experienced the same issue and had replaced the cooling fan assembly for the magnetron. I ordered the parts for the assembly (motor, fan, and support), and replaced them and this fixed the problem. It took about 10 minutes to replace the parts, but lowering the unit and disassembly took around 45 minutes.

Microwave won't turn on or has no power? A failed thermostat often causes complete power loss. Moderate DIY repair requires disassembly to access.

Do-It-Yourself Stories from Customers like You No power.   William R. • Jacksonville , FL • February 12, 2019

I checked for the reasons there was no power to the microwave. Then I talked with the technician at AppliancePartsPros who stated that it was most likely a blown or defective fuse. My LG microwave has two thermal fuses, a fuse assembly with two prongs and a short (1 inch) barrel type fuse. I replaced all of them after viewing YouTube videos and then reviewing the diagram for my microwave on the AppliancePartsPrps website. That was very helpful in locating where the fuses were installed. It... Read more

I attempted to diagnose the four thermostats/thermal switches in the microwave....two right behind the control panel, one on top of the cooking cabin, and one under a metal shroud above the magnetron. While checking continuity with a voltmeter, i questioned one of them behind the control panel and the one above the magnetron. I then noticed a burn mark on the plastic connector sleeve for the one above the magnetron. I took a scrap piece of 14 gage copper wire and beat the ends flat with a... Read more

Do-It-Yourself Stories from Customers like You Broken door handle maytag range hood microwave   Ryan S. • Valparaiso , IN • September 12, 2014

I took the door off via the top torx screw pin, then pryed apart the plastic trim piece that surrounds the inner window pane with the mesh screen. I removed the inside window panel which was a little tricky, and replaced the door handle. I did it with nothing more than a flathead, Phillips, and a torx. It was very nice that AppliancePartsPros posted a link with video instructions. This easily saved me a couple hundred bucks since I didn't have to have Maytag do it. By the way,... Read more
