Do-It-Yourself Stories from Customers like You Interior light and turntable failed at the same moment.   Stacey B. • New Bern , NC • February 01, 2021

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.

Do-It-Yourself Stories from Customers like You My microwave vent grill kept falling on my head when i opened my microwave   Christopher D. • Kernersville , NC • February 23, 2015

Well, I gotta say I was happy to find you still had parts for almost 20 year old microwaves. The microwave itself worked fine, so I hated to have to buy a new one, but I just couldn't take being hit in the head anymore; and my fix of using string and wire to tie it to the surrounding cabinets was unsightly to say the least. I'm glad I did some research and found this part - all I had to do was pop it in place and now the vent grill is secure. Problem solved with minimal cost. Read more

It is a small, snap-action switch mounted near the door latch mechanism. Replace this switch if the microwave won't start, runs with the door open, or blows a fuse when the door is closed.

Do-It-Yourself Stories from Customers like You Door latch broke also causing the fuse to blow   James M. • Ocean View , NJ • April 28, 2017

It is difficult (if not impossible) to remove the electronic switches from the hard plastic latches. I replaced all three switches and both the upper and lower latches I also replaced the main 20 amp ceramic fuse which blew out when the latch/switches failed. Read more

Do-It-Yourself Stories from Customers like You Broken screw holes in top of plastic vent grill   Spencer H. • Weston , FL • July 25, 2016

My microwave was stainless steel. I ordered the part for stainless steel, but it was not identical in color. It was black and not the gray color of stainless steel. However, I removed the stainless steel (the actual metallic) frame from my broken grille (bent back a few metal tabs and pried loose the adhesive tape with a putty knife). Then I placed it on my new black plastic part and reassembled to the microwave. I find that it looks perfectly acceptable and maybe even nicer with the black as... Read more

Do-It-Yourself Stories from Customers like You Microwave turntable motor overheated and melted tray coupler   Terry H. • Columbia , MO • May 31, 2018

Obtained the replacement motor and tray coupler from Appliance Parts Pro. Video of the typical replacement was very helpful to show what to expect and how to replace the motor and coupler. The removal of the bottom plate was held in place by several phillips screws. The motor was attached with two torx screws. The electric connection clips to the motor required needle nose pliers to pull them off. The tray coupler was simple to install after the motor was secured and bottom plate was replaced.. 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

Do-It-Yourself Stories from Customers like You Kitchen aid architect ii microwave turntable stopped rotating   Stephanie M. • Colorado Springs , CO • March 25, 2017

First, it was going to cost $95 for an appliance guy just to look at it! I figured there would be an upcharge on the parts + labor on top of the $95, so I took a chance & decided my husband & I could fix it cheaper; we were right, but it was a 3 week process (luckily, we have another microwave in the basement we were able to use in the meantime). I googled the microwave model #, then price checked the same item I thought we needed; printed off the diagrams of the various microwave "systems" &... Read more

Microwave Diode
Genuine Lg part

Microwave won't heat or makes loud buzzing noise? The diode regulates magnetron current flow. Simple repair—test with multimeter for continuity.

Do-It-Yourself Stories from Customers like You Our microwave made a "pop" sound and stopped working/   Daniel D. • Chesterfield , MO • September 12, 2020

I have a multimeter so I was able to check the fuse per website recommendations and it was blown. However, the capacitor on the microwave was also original so I elected to replace the capacitor, fuse, and the ground protect diode. The repair was very simple (making sure the capacitor was discharged before replacing) and the microwave is now up and running again. Excellent trade to buy $40 worth of parts rather than a new $400 microwave. One nit - Kenmore puts a screw in the back that... 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.
