The Thermistor Assembly is an OEM component specifically designed for front loading LG washing machines. It plays an important role in monitoring and regulating temperatures during heated wash cycles. The thermistor detects temperature changes within the wash drum and sends this information to the control board to ensure clothes are washed at the optimal temperature.

Causes of a bad thermistor assembly can include general wear and tear over time, exposure to extreme temperatures, or damage due to impact or mishandling during cycles.

Symptoms of a bad thermistor assembly include:

• Inability to reach or maintain set temperatures
• Fluctuating water temperatures
• Error codes related to temperature sensing

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

This NTC thermistor is a refrigerator temperature sensor that monitors cooling system temperature and helps the control board maintain proper operation. It replaces a failed sensor to restore accurate temperature sensing and reliable cycle control. What it does:
