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.

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 Our microwave made a "pop" sound and stopped working/   Daniel D. • Chesterfield , MO • September 12, 2020

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
