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

Time Delay Fuse
Genuine Lg part
By: Lg
Part Number: 3B74133Q

The Time Delay Fuse is an OEM part for LG microwaves. This fuse provides a safety mechanism by delaying the flow of electricity, protecting the microwave's electrical components from power surges and ensuring the appliance operates safely. It helps to prevent immediate damage in the event of a power surge or electrical fault, thus prolonging the lifespan of the microwave.

Over time, the time delay fuse can become damaged due to electrical surges, wear and tear, or faulty connections. If the fuse blows, it can disrupt the microwave’s ability to function correctly.

Symptoms of a bad time delay fuse include:

  • The microwave not turning on
  • No response from the microwave control panel
  • The microwave stopping unexpectedly during operation
  • Electrical issues or blown circuits in the microwave

This OEM LG part is also compatible with Sears/Kenmore models.

This part fixes the following symptoms
  • Won't start

Genuine Lg part
By: Lg
Part Number: 4970WRA001G

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! Read more

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.

Microwave Diode
Genuine Lg part

Part Number: 6021W3B001V

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 Microwave turn table stopped rotating   Thomas T. • Willow Grove , PA • September 08, 2015

I googled the make and model, and found the part on AppliancePartsPros.com. The underside of the oven has a metal grille with numerous openings of various shapes and sizes. There is a rectangle that is punched into this grille, just below the motor. I pried between the vent holes to snap the connections near the perimeter on the punched rectangle. I only did this on three sides. Then pry up the rectangle away from the connected side. Undid the hold down screw, separated the motor from the... Read more

Do-It-Yourself Stories from Customers like You The glass tray from the microwave had broken and the interior light bulb was burnt out   Rebecca H. • Linesville , PA • May 27, 2015

The tray was an easy fix as I looked up Kenmore Microwave and ordered the replacement. The light bulb was a little trickier as to replace it you must have a special screwdriver that has a 5-pointed bit with a hole in the middle. This is because nothing else is safely serviceable on the microwave. I unplugged the microwave and moved it to my kitchen table to do the work. The entire outside case had to be removed to access the light bulb which is on the upper right side. You must unplug the... Read more
