Thermostat
Genuine Lg part
By: Lg
Part Number: 6930W1A003X

The Magnetron Thermostat is an OEM part for LG microwaves and built-in ranges. Its primary function is to monitor the temperature and ensure that it remains within a safe operating range. If the temperature exceeds the preset limit, the thermostat will interrupt the power supply to the magnetron, preventing overheating and potential damage.

Symptoms of a bad magnetron thermostat may include:

  • Microwave not heating food evenly or at all
  • Inconsistent or weak heating performance
  • Microwave shutting off or displaying error codes related to temperature issues

This OEM LG part can also be used on Kenmore/Sears appliances.

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.

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

Careful placement of new screws into the inside of the outer door that now hold the frame assembly to the door secured the frame assembly to the outer door.
