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
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:
This OEM LG part is also compatible with Sears/Kenmore models.
Called AppliancePartsPros because of good experiencing diagnosing problem with a dishwasher repair. We definitely are modest income amateurs! Same excellent response to our questions. Three possible causes. Used easy search menu to fine replacement parts. Bought all three, knowing that if all not needed, the others could be returned (within 365 days) for refund. Replaced the capacitor successfully after calling to get more help with a couple of places where we got stuck. Oven now works... Read more
Microwave has no power or won't heat? A blown thermal fuse is often the cause. This safety part protects against overheating. DIY repair in 30 minutes.
It is difficult (if not impossible) to remove the electronic switches from the hard plastic latches. I replaced all three switches and both the upper and lower latches I also replaced the main 20 amp ceramic fuse which blew out when the latch/switches failed. Read more

It helps prevent overheating by monitoring and controlling the internal temperature, protecting both the appliance and the user.
Causes of a bad thermostat can include wear and tear over time, electrical malfunctions, or damage from power surges.
Symptoms of a bad thermostat include:
This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.
GE Microwave/Convection Oven. Removed case (carefully). Tested in-line power cord fuse with multi-meter. Fuse was good. Noticed a scorch mark on a wire connected to the oven cavity thermal fuse. The fuse appeared to have been overheated from too much movement in it's mount. Removed part from unit and used number on the part to order a new one. Installed new part, re-assembled, and unit works fine. Read more
Microwave won't power on or turn on? Failed thermostat causes complete power loss. This safety part protects against overheating. DIY repair in 30 minutes.
I attempted to diagnose the four thermostats/thermal switches in the microwave....two right behind the control panel, one on top of the cooking cabin, and one under a metal shroud above the magnetron. While checking continuity with a voltmeter, i questioned one of them behind the control panel and the one above the magnetron. I then noticed a burn mark on the plastic connector sleeve for the one above the magnetron. I took a scrap piece of 14 gage copper wire and beat the ends flat with a... Read more

Microwave won't power on or has no display? This thermostat monitors internal temperature to prevent overheating. Easy 15-minute DIY fix for most models.
Microwave won't turn on or has no power? A failed thermostat often causes complete power loss. Moderate DIY repair requires disassembly to access.
I checked for the reasons there was no power to the microwave. Then I talked with the technician at AppliancePartsPros who stated that it was most likely a blown or defective fuse. My LG microwave has two thermal fuses, a fuse assembly with two prongs and a short (1 inch) barrel type fuse. I replaced all of them after viewing YouTube videos and then reviewing the diagram for my microwave on the AppliancePartsPrps website. That was very helpful in locating where the fuses were installed. It... Read more
Microwave has no power or won't start? A faulty cavity thermostat often causes complete shutdowns. This part restores temperature control in 5-10 minutes.
Microwave has no power or won't turn on? This fuse cartridge protects against electrical overload. Requires removing outer cover to access and replace.
Removed microwave from the built in cabinet (probably the hardest part) and took off top cover (screws on side and back). Had previously blown the power fuse 2 times in this microwave, so I checked the fuse first using an ohmmeter. This time fuse was good. Traced the power wires around to top side of microwave and saw the overheat "therm" switch. I believe the therm is installed there as a safety feature to open the power circuit to the microwave in case something was to overheat for any... 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
If your microwave shuts off mid-cycle or won't heat, the thermostat may have failed. This safety control monitors temperature and protects components.
I replaced the control board behind the keypad. Read more
Microwave shuts off without beeping or won't power on? A failed thermostat often causes overheating shutdowns. This safety switch is moderately easy to replace.
Replace Thermostat on top of cavity. The thermostat is attached via 2 bending sheet metal tabs. Ours blew because the two wires connected to thermostat shorted, connectors melted. The short was caused by buildup of grease under thermal wire cover, shorting both leads. The unit is used heavily. This is the first thermostat to go. I had to replace wire connectors that connected to thermostat as well since the connectors were melted as well. Helpful hint. The grease build up was probably caused by... Read more
