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
Oven goes dark after self-clean? This thermal fuse cuts power when overheating occurs. Common failure after cleaning cycles. Easy DIY repair.
First, don't self clean your oven before the holidays. In fact, read up on what damage the self cleaning feature can do to your oven. How did I fix it, I went on line and saw the comments of appliancepartspros.com. I figured out that it was the thermal fuse that probably went wrong since my oven just went lights out after the cleaning. My oven is a Kitchenaid model # KEBS179BSSOO. The part for this model is AP6022801 or WPW10545255. I spoke with technical support but I still had questions. I... Read more
Oven won't heat after self-cleaning? This thermal fuse cuts power when overheating occurs. Common DIY repair takes under 10 minutes with basic tools.
This is for the Whirlpool in-wall double oven GBD307PDS10. No power and the door locked after the shutdown before the self-cleaning cycle was over. I watched some video and this is a known issue the fuses blow during self-cleaning. I opened the door with a 90-degree hook, an easy task. Took doors off (watch video from others), unscrewed from the wall, and made a very small platform. and took the oven out (need two people and take the doors off first. The doors are heavy and you won't lift the... Read more
Oven won't heat after self-clean cycle? A blown thermal fuse cuts power when temps spike. Easy DIY fix—disconnect power, test with multimeter, replace.
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. AppliancePartsPros.com is one of the... Read more
This is a fixed high-limit thermostat used in ranges and ovens to monitor internal temperature and cut power to the heating element if the oven exceeds a safe operating temperature. It acts as a safety device to prevent overheating and potential fire hazards. Replace this thermostat if your oven is not heating at all, shuts off prematurely, or if you have confirmed a lack of continuity through the component with a multimeter.
Replaced the thermst-fix and the thermal fuse oven now works great Read more
This thermal fuse is a safety device designed to cut power to the oven if internal temperatures exceed a safe limit, preventing overheating and potential fire hazards. It is a one-time-use component that cannot be reset once it has tripped. Replace this fuse if your wall oven will not heat at all or has no power, especially after a self-clean cycle or an overheating event.
Replaced fuse. It took much longer to get the oven out of the wall to access the fuse and replace the front panel than to do the repair. This fuse failed at the end of the cleaning cycle for the bottom oven and left the door locked because the open fuse removed the 120v power from the control board. The locked door made it impossible to remove one of the screws holding the wall oven in place. However, after I ground off the head of the screw behind the edge of the locked door I was able to...

Oven won't heat or has no power after self-clean? A blown thermal fuse is likely the cause. This safety part cuts power if temps get too high.
Oven won't heat after self-cleaning? A blown thermal fuse cuts power to protect the control. Requires pulling the oven out to access rear panel.
Like a boss! Seriously, removed oven from wall (2 screws), removed about 15 sheet metal screws from front and top covers, unplugged wire harnesses one (or a few) at a time. Reassembled. Hint. Take a picture of wiring before removing and mark old parts (especially thermal fuse) with sharpie before removing so you don't get confused. It's really hard to tell a used electrical part from a new one. Read more
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
