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.

  • Microwave shutting off or displaying error codes related to temperature issues

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

Fuse
Genuine Ge part
By: Ge
Part Number: WB27X10928

The Fuse is an OEM part for GE microwaves. It serves as a safety device designed to protect the microwave from excessive current that can cause overheating and potential fire hazards. When the current flowing through the microwave circuit exceeds a certain level, the fuse blows or breaks, cutting off the power to prevent damage or fire.

Common causes for a fuse to blow include power surges, faulty wiring within the appliance, or the use of microwave inappropriate containers that cause sparks. It is essential to address these issues not only to replace the fuse but also to correct the underlying problems to prevent future failures.

Symptoms of a bad fuse include:

  • The microwave suddenly stops working.
  • No signs of power or response even when the microwave door is closed and the start button is pressed.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

Do-It-Yourself Stories from Customers like You The GE Advantium Oven completely shut down. No lights, no sign of life at all.   Denny E. • Waynesboro , VA • March 14, 2014

I read on line about other such ovens doing the same thing mine was doing, absolutely nothing! I even read stories of a major retailer telling customers to throw the microwave away. There's nothing you can do to fix it. After replacing a simple fuse that I ordered from you, the Advantium is as good as new. It took a grand total of 5 minutes to make the repair. The shipping cost more than the part, but it was all very worthwhile. Read more
