This boxed film capacitor provides stable noise suppression and transient protection for appliance control circuits, helping motors and electronic boards run more reliably. It replaces a damaged or failing capacitor to restore normal electrical filtering. What it does:

  • Smooths voltage spikes and reduces electrical noise that can interfere with control boards.
  • Helps prevent nuisance tripping and erratic control behavior caused by transients.
  • Common symptom indicators: intermittent control errors, humming or motor performance issues, or failure to start.
  • Works as part of the appliance's power/filtering network to protect sensitive electronics.
What's included: One boxed film capacitor. Install notes:
  • Always disconnect power at the breaker and verify power is off before servicing.
  • Capacitors can hold charge—discharge safely and use insulated tools when handling.
  • Replace with the exact OEM part number to ensure proper fit and electrical characteristics.

The Thermistor Assembly is an OEM part for LG air conditioners. It is typically located near the evaporator coil or in the air intake area of the unit. It measures the ambient temperature and sends signals to the control board to adjust the cooling output accordingly.

Causes of a faulty or malfunctioning thermistor assembly can include normal wear and tear, exposure to extreme temperatures, or electrical issues. These factors can lead to inaccurate temperature readings, improper cooling performance, or erratic behavior of the air conditioner.

Symptoms of a bad thermistor assembly may include:

  • Inconsistent cooling or insufficient cooling
  • Inaccurate temperature display on the control panel
  • Frequent cycling on and off of the compressor

This OEM LG part can also be used on Kenmore/Sears appliances.
