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.
Causes of a faulty magnetron thermostat can include electrical malfunctions, component failures, or physical damage. These factors can result in issues such as erratic heating, microwave not heating properly, or the appliance shutting off unexpectedly.
Symptoms of a bad magnetron thermostat may include:
This OEM LG part can also be used on Kenmore/Sears appliances.
Did some Google searches and most comments concerning this issue on LG stoves indicated the high temperature thermostat malfunctions when using the self cleaning function. This malfunction causes complete loss of power for the entire stove and locks the oven door. Since I wasn't completely sure if it was the thermostat or where it was for that matter, I called a service tech to troubleshoot the stove. He was able to determine it was the thermostat and further tested his findings by... Read more
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:
This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.
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
Oven won't heat or both elements stopped working? A faulty thermal fuse cuts power to prevent overheating. Easy DIY fix with basic tools in under an hour.
Replaced the blown heating element. I also only to be on the safe side, replaced the over temp sensor. I checked it with the meter when I pulled it out and it was ok. Tested ok. Thank you very much for the less than 2 day delivery on the part. Read more
Microwave won't start or is completely dead? This fuse protects against electrical overload. Requires disassembly to access. Often replace with switches.
After doing some research the problem appeared to be the door safety switches. I ordered 3 new ones to replace all the original ones. Some minor disassembly of the microwave front was required to reach the fuse and switches. To reach the switches the control panel wires needed to be unplugged and the panel removed. After doing that replacing the switches was pretty strait forward. As of this comment the microwave has worked for 5 days without blowing the fuse so far. This has probably fixed the... Read more
Oven won't heat or shuts off during baking? A faulty thermal fuse cuts power when detecting excessive heat. This safety device protects your range.
The F9 error code is supposed to indicate that the door lock mechanism has failed. My oven would give the F9 code and turn off during normal baking at 400 F after about 30-40 minutes. It turns out that GE must have programmed the error codes incorrectly in my model, because the real problem was that my control board cooling fan was no longer functional, and one of the two thermal switches was shutting off the unit when the control board area got too hot.

Microwave won't turn on or has no power? A blown fuse is often the cause. This safety component protects against electrical surges and short circuits.
I have a Jenn-Air microwave that didn't turn on and had no lights. It just stopped working completely. I unplugged the unit and had to remove the rear cover using a *security screw kit* that prevents people from opening the rear panel. Once opened, I removed the fuse and testing it with an OHM reader to determine that the fuse went bad. But I also had to determine why the fuse blew and noticed a sticky oily substance under the Capacitor. I used a rubber glove and needle nose pliers to... Read more
Oven won't heat or shuts off during use? A blown thermal fuse cuts power to prevent overheating. Simple diagnosis with a multimeter, quick replacement.
Oven won't heat or can't hold temperature? This thermal switch monitors oven temperature and protects internal components. Common fix for heat issues.
After 2 repair men, many parts replace it still didn't work, Did research on line and found out the thermal fuse would need to be replace.. Read more
This time-delay fuse protects the appliance's power circuit by opening when current exceeds a safe level while tolerating brief inrush current. Replacing a blown fuse can help restore power once the root cause is corrected. What it does:
I read up on others with this problem of microwave-wall oven combination Whirlpool Gold. We live in a very rural area and were not able to get ANYONE to service it - had 2 companies come out to inspect but they never returned. I have wonderful news! We replaced the fuse, bus fuse, and light bulb (quit working 2 years ago) and all is working. Thanks for the information and for the part diagram. Couldn't have done it without you. Read more

Microwave shuts down during use? This thermal cutoff thermostat prevents overheating by interrupting power when temperatures exceed safe limits.
My daughter that she turned timer on but hit cook with nothing in the microwave. I was able to figure it was one of the four thermal cutoffs. It was obvious which one literally fried. Replaced that one worked like it was new. Took a lot of photos while dismantling and labeled the screws. Wasn't that hard just be careful of the capacitor Read more
