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. 

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.

This foot is a small rubber base pad that supports and stabilizes the appliance on the countertop or cabinet surface. Replacing a worn or missing foot helps keep the unit level and reduces vibration and slipping.

• Common failure signs: no heat in those modes, extended preheat times, uneven results, tripped breaker, or a visibly blistered/broken element
• Restores reliable heating performance when the original element is open or shorted

• Disconnect power and let components cool before servicing
• If servicing a microwave, remember high-voltage components can retain a dangerous charge; discharge the capacitor and consider service if you're not experienced
• Handle the element by its brackets; avoid bending the sheath or stressing terminals
• Move wires one at a time to the new part and verify element continuity with a multimeter before reassembly

This radiant surface element mounts beneath the glass cooktop to heat a burner zone on your range. Replacing a failed element restores consistent, responsive heating and reliable temperature control for everyday cooking.

• Provides controlled electric heat under the glass for the selected cooking zone
• Works with the range controls to cycle on/off and maintain the set temperature
• Common symptoms: burner won't heat, heats intermittently or only in spots, or the indicator comes on but the surface stays cold
• Visual clues can include a broken or blistered heating coil visible beneath the glass

• Disconnect power at the breaker and allow the cooktop to cool completely
• Lift/prop the glass top per service procedure; note wiring and bracket locations before removal
• Transfer any brackets/insulators from the old element and make secure, like-for-like connections
• Handle the glass and element carefully; test operation before final reassembly
