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 Removed 1 year old microwave to paint kitchen internal thread assembly stripped   Joel L. • North Richland Hills , TX • December 01, 2016

I took the machine screws out of the outer panel for the right side only. Then pull the panel back a bit to release the lips from the front of the machine and had immediate access to the internal assembly that housed mounting nut. Order the new parts from AppliancePartsPro.com during the Thanksgiving week. Still received via FedEx in short time due to their same day shipping - which was greatly appreciated and surprising. Most small part places take a while to get the product out the door,... Read more

Do-It-Yourself Stories from Customers like You Smh1816s samsung microwave went completely dark no controls no lights receptacle good   John S. • Olathe , KS • March 17, 2015

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

Microwave High Voltage Capacitor
Genuine Whirlpool part
By: Whirlpool
Part Number: W10850446

Microwave not heating or making loud humming noise? The high-voltage capacitor supplies power to the magnetron. DIY repair in under an hour.

Do-It-Yourself Stories from Customers like You My microwave was working at half power   Eric H. • Tonawanda , NY • October 30, 2015

I ordered a new magnetron and a new capacitor and after they arrived I set to work. I took plenty of pictures with my phone to remind me how the components came apart but it was pretty straight forward. Once the new parts were in and everything was reassembled the microwave worked good as new. The repair was less than a third the cost of replacement and no special tools are required. Just be careful to discharge the capacitor. This website is a great resource. Read more

The grill vent is only held in place by two screws. Super simple fix. Remove the two screws and the old grill vent, position the new vent and put the two screws back in. Replacing the cord required that cabinet to be removed. Lots of screws on the back, top and bottom. Once the screws were removed, the cabinet pulled back. The power cord connections were then clearly visible. Undid the two wire connectors and unscrewed the ground wire from the body to remove the old power cable. Installed the... Read more
