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.

He was able to determine it was the thermostat and further tested his findings by... Read more
The Thermostat is an OEM part for LG wall ovens. It is a temperature-sensitive cut-off switch located near the oven's heating elements that monitors interior temperatures and prevents overheating within the appliance.

My thermostat was clearly deformed, and I had never run a self clean like other with testify to. Simply replace it - easy. Oven worked like new. Read more
This time delay fuse protects the appliance from overheating by opening the circuit when temperatures exceed safe limits. It's a direct-replacement electrical safety fuse used in heating circuits to help prevent damage and fire risk. What it does:
Actual problem was due to a poor connection from the circuit board and HV transformer, over time this poor / loose connection began to arc causing enough heat to physically melt the connector and the contact to the thermistor. the problem was obvious but I still followed procedures to check all the components.*** NOTE*** ALWAYS UNPLUG DEVICE FIRST, WITH MICROVAVES, ALWAYS, ALWAYS, DISCHARGE HV CAPICITOR, IT CAN KILL YOU! just take your time testing components, following your electronic...
