Genuine Lg part

Kenmore Thermostat

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. 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:

Microwave not heating food evenly or at all
Inconsistent or weak heating performance
Microwave shutting off or displaying error codes related to temperature issues

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

This part fixes the following symptoms

Won't start
No heat

Do-It-Yourself Stories from Customers like You High temperature thermostat went bad after running self clean function John V. • Longmont , CO • September 09, 2014

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

Kenmore Time Delay Fuse

5.0 (21)

By: Lg

Part Number: 3B74133Q

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:

The microwave not turning on
No response from the microwave control panel
The microwave stopping unexpectedly during operation
Electrical issues or blown circuits in the microwave

This OEM LG part is also compatible with Sears/Kenmore models.

This part fixes the following symptoms

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.

Do-It-Yourself Stories from Customers like You No power. William R. • Jacksonville , FL • February 12, 2019

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

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

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.

Kenmore Thermistor (Temperature Sensor)

5.0 (1)

By: Lg

Part Number: 6322W2A001A

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
Use when the existing sensor fails to report correct temperatures or the part number matches.

What's included: One thermistor sensor. Install notes:

Always disconnect power to the appliance before servicing to avoid shock or damage.
The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

Do-It-Yourself Stories from Customers like You Microwave would not microwave Richard E. • Cape Coral , FL • January 05, 2020

Replaced the Humidity sensor, Thermistor and door switches. I replaced these thinking the problem was one of the items but didn't want to trial and error one part at a time. Plus the cost was reasonable so if these didn't help I wasn't out a lot of money. I sense the door switch was the problem. Replaced all items and the microwave works great. Thanks for the advice and the cost of the parts. Read more
