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.
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...

Kennmore elite microwave with f5 error code Julius D. • Oxford , PA • February 11, 2017
When Microwaving food, the display panel would seem to act normal, but the typical microwave sound would be absent. No microwave action would occur. Eventually an F5 code would display. Problem was the upper door switch. Found it by opening up the cabinet, removing the display panel (1 screw and a couple of plugs) and testing all three micro switched with a meter. Two switches are for the door and one for some kind of ventilation flap. They are all in the same area. Go to YouTube to see...

Microwave door won't stay closed or latch? This door latch spring provides tension to secure the door shut. DIY repair in under 10 minutes with video help.
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!

Microwave turntable would not spin Charles B. • Uniontown , PA • November 23, 2014
Removed 8 screws from bottom panel on microwave. Pulled two prong plug off old motor. Read supplied voltage off motor decal and tested for it. Deemed motor to be bad and changed it. Works great. After tearing old motor apart it seems a liquid got in there from inside microwave. No seal on motor. Bad design flaw in my opinion.

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...

Microwave would not microwave Richard E. • Cape Coral , FL • January 05, 2020
Replaced the Humidity sensor, Thermistor and door switches. I replaced these thinking the problem was one of the items but didn't want to trial and error one part at a time. Plus the cost was reasonable so if these didn't help I wasn't out a lot of money. I sense the door switch was the problem. Replaced all items and the microwave works great. Thanks for the advice and the cost of the parts.
