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. 

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. 

Replacement window glass that restores a clear viewing area in the appliance door and helps maintain a clean, sealed surface. Ideal for replacing cracked, chipped, or cloudy glass to improve visibility and safety. What it does:

• Replaces cracked, chipped, or fogged glass to restore appearance and function.
• Serves as the door's viewing surface and works with the door assembly and trim.
• Inspect surrounding gaskets, trim, and fasteners when replacing the glass to ensure a proper fit.

• Disconnect power (and water, if applicable) before attempting any repair.
• Wear cut-resistant gloves and eye protection when handling or removing glass.
• Door disassembly and removal of trim or retaining clips is commonly required.
• If the glass is shattered, remove broken pieces carefully and dispose of them per local regulations.

The Bake Element is an OEM part for LG ranges. This part provides the necessary heat for baking by distributing heat evenly from the bottom of the oven cavity. 

Causes of a bad bake element can include normal wear and tear over time, exposure to high heat leading to deterioration, or electrical issues causing the element to short out.

Symptoms of a bad bake element include:

• Oven not heating evenly or not reaching the set temperature
• Visible damage such as breaks or blisters on the element
• The element not glowing red when in use
• Longer cooking times than usual

This OEM LG part is also compatible with some Kenmore models.
