Do-It-Yourself Stories from Customers like You Several keys on the touchpad unexpectedly stopped working (ie start cancel setup vent fan light cook reheat soften/melt & defrost quick defrost)   George W. S. • Kennesaw , GA • October 08, 2016

After extremely poor support from WhirlpooI and researching numerous U-Tube videos, I fully troubleshot potential failed components and connections. All appeared to function properly, so I reassembled the unit and experienced the same problem as before. I then narrowed down the problem to either the Touchpad ($57+$8 shipping) or the control board ($295+shipping). If those did not work, then a new Microwave of better quality, reliability and support than original microwave, Unfortunately,... Read more

Genuine Whirlpool part
By: Whirlpool
Part Number: W10269458

Microwave displays 'close door' message or won't start? The door interlock switch is likely failed. Moderate DIY repair—replace all 3 switches together.

Do-It-Yourself Stories from Customers like You Light flickering when open door & stays on when door opened   Jo B. • Vandalia , OH • March 01, 2020

After checking other reviews, we decided it was best to replace the interlocks, cam and all three switches. You're going to need a phillips screwdriver, star driver, small screwdriver and needle nose pliers. You need to remove the ONE Phillips screw above the control panel inside the vent. The contol panel is on hinges that you can slide up and towards you. Using caution remove the wires noting how they're connected. Pinch the top of the white connectors and wiggle them free. We couldn't get... Read more

Switch
Genuine Whirlpool part
By: Whirlpool
Part Number: W10211972

The Switch is an OEM part for Whirlpool microwaves. It controls the turning on and off of power to the microwave during cooking cycles as well as detects positions within cycles to signal appropriate actuations of the microwave's magnetron, fans, and lights. The switch is a crucial electrical component that facilitates the fully automatic operation of preset cooking programs.  

Causes of a bad switch can include wear and tear over time or unexpected surges that cause electrical component failure.

Symptoms of a bad switch include:

  • Cooking programs failing to advance properly or stopping mid-cycle unexpectedly
  • The microwave failing to turn on or experiencing power issues  
  • Random noises, humming, or lights occurring when the microwave is supposed to be idle
  • Buttons or controls acting intermittently unresponsive

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances. 

Do-It-Yourself Stories from Customers like You Microwave needed new door switches   Marie W. • Columbus , OH • March 01, 2017

I'm a 56 year old divorced woman. I started doing these kinds of repairs to save some money and honestly, to see if I could. So yes, if I can do it, it's not that tough to do. My microwave is built in above the stove - getting it down and back up was the hardest part of the job. An extra pair of strong hands really helps-for anybody, not just a 56 year old woman. The actual repair was pretty easy. Most likely problem was pretty obvious after a little research. Easy to take off cover, get... Read more

Do-It-Yourself Stories from Customers like You We purchased a discounted microwave it was not fully equipped with its accessories   Paul C. • Roseville , CA • September 16, 2018

I have used appliance parts pros before, their website is easy to use. I typed in the model and serial numbers, of course the number I have is rare, It did not show up on the list of models. It made me a little hesitant to submit the order. All three products came in the same box and on the same date it was promised. Just after opening the package I put everything in the microwave and I was relieved when everything fit perfectly. Read more

Do-It-Yourself Stories from Customers like You Didn't heat.   Harry W. • Maple Park , IL • January 21, 2018

My son told me that almost all the microwave ovens that came into the repair center he worked at, 15 years ago, had a defective magnetron. I ordered a magnetron, and sat back until one shipped. The one that came, the first time, was in a small factory cardboard box, which was in a large bubble-pak Fedex envelope; which didn't show any signs of abuse. Inside, however, the factory box was beat up. Removing the magnetron, I noticed that the socket, as well as its' pins, was bent, and loose in the... Read more

Do-It-Yourself Stories from Customers like You Lg microwave door would not latch closed   Audrey S. • Rochester , NY • February 05, 2018

Ordered door latch part and new spring. You Tube video helped me identify what I needed. I tried the fix recommended and it didn't work so I ordered the parts. It took less than 5 minutes to switch out the old for the new. If the door doesn't latch, you can't run the microwave and it's key. It wasn't an expensive or hard fix to get my microwave up and running again. So pleased with AppliancePartsPros for having what I needed and being reasonable about pricing. Turnaround time was excellent! Read more

Do-It-Yourself Stories from Customers like You Microwave outer plastic brittle cracking broken   Karl M. • Westminster , MD • January 21, 2023

Whirlpool microwave model MH8150XJQ-0 manufactured May 2002. The outer door frame and vent grill became brittle, developed cracks and breaks with little pieces around the screws falling off... that sort of thing. It's over 20 years old so no complaints. The rest of the microwave is fine and since it's mounted over the stovetop, I don't want to deal with measuring, selecting, removing, installing, etc. when this one still works. I'm glad AppliancePartsPros had the parts. Anyone considering this... Read more

Knowing the odds of 2 failures occurring at the same exact time was unusually high, I just searched your site for what other broken items might affect these two failures. Came up with next control item upstream and tallied that item failure with percentages of successful repairs, (4 mins.) door safety switch. Since I had to change out the most likely of the 3 and since I was already was going to be into the switch panel I ordered all 3 and swapped them all out to cover my butt, as they were... Read more

Do-It-Yourself Stories from Customers like You Loud hum/buzz & no heat   Greg S. • Springfield , VA • November 30, 2015

Replacing a magnetron in my particular 9-year-old microwave (a microwave/hood combination) was not a simple “plug & play” operation. That is why I am placing this in the slightly difficult area. First, it takes 2 people to remove the microwave from the top of the stove. Next the main outer panel need to be removed. After that, 2 sheet metal panels need to be removed in order to expose the high voltage components for testing. Always discharge the high voltage capacitor first before doing... Read more
