The Thermistor Assembly, PTC is an OEM replacement part for LG refrigerator models. As a key sensor, the thermistor monitors and reports temperature levels inside fridge and freezer compartments to the main control board. It ensures optimal cooling through precise thermal feedback.
Causes of a bad thermistor can include failure to calibrate accurately due to age, loose connections disrupting readings, or external impacts compromising sensor integrity.
Symptoms of a bad thermistor include:
- Abnormal or inconsistent temperatures within fridge sections
- Compressor and fans cycling on and off too frequently
- Error codes relating to temperature display
- Inability of the control board to read temperature values
This OEM LG part is also compatible with Sears/Kenmore. Replacing a faulty thermistor restores exact temperature control for safe, long-lasting food storage.
