• Disconnect power to the appliance before servicing; shut off gas/water if applicable
• Access the control panel to reach the user interface board
• This is a board-level repair; note switch orientation. Replacement may require desoldering/soldering per OEM procedure
• Use ESD precautions and avoid overheating PCB pads; test button function before reassembly

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 single wiring harness connects appliance components to deliver power and signals, restoring reliable electrical continuity and component communication. Use when a damaged or corroded harness causes intermittent operation or complete failure of the connected part. What it does:

• Routes power and signal connections between components to ensure proper operation
• Replaces broken, frayed, or burned wiring that can cause intermittent power or component failure
• Helps stop symptoms like no power to a component, erratic behavior, or intermittent operation
• Maintains correct connector fit to prevent loose connections and arcing

• One single wiring harness as shown

• Disconnect power before servicing to avoid shock or short circuits
• Match connector shapes and terminal positions; do not force connectors
• Inspect mating connectors and terminals for damage or corrosion before installation

The Thermistor is an OEM replacement part for LG gas ranges. It serves as a highly sensitive temperature sensor mounted inside the oven cavity. 

Symptoms of a bad thermistor include:  

• Inability to select certain cooking modes like bake or convection that involve temperature control
• Fluctuating or inaccurate temperature readouts on oven displays
• Irregular cooking outcomes like hot/cold spots inside the oven
• Repeated error codes regarding temperature sensing issues

Causes can be attributed to prolonged exposures to heat and intermittent combustion byproducts inside the oven. Over a decade of use, these conditions may degrade the thermal and electrical properties of sensor components. 

This genuine LG replacement thermistor installs effortlessly. Installing a new thermistor restores temperature monitoring required for reliable gas oven performance. 

A convection fan assembly that circulates hot air inside the oven cavity to promote even baking and roasting. Replacing a worn or noisy fan helps restore consistent cooking performance and airflow in convection ovens. What it does:

• Circulates heated air for more even temperature distribution and improved browning.
• Restores proper airflow when the existing fan is noisy, loose, or failing to spin.
• Helps resolve uneven baking, hot spots, or longer cook times caused by poor air circulation.
• Works as the rotating airflow component of the oven's convection system.

• Disconnect power to the appliance before beginning any work to avoid shock risk.
• Access typically requires removing the oven interior panel or rear access panel; keep track of fasteners.
• Handle sharp sheet-metal edges and support the fan while disconnecting wiring or mounting hardware.

This replacement bar serves as the exterior door handle/trim that lets you open and close the appliance door smoothly while restoring the unit's original appearance. It's a direct-replacement style part designed to fit the factory mounting points. What it does:
