Fix F4 error codes or sensor cook failures with this microwave humidity sensor. Restores automatic cooking cycles. Moderate DIY difficulty.

Do-It-Yourself Stories from Customers like You Microwave would not microwave   Richard E. • Cape Coral , FL • January 05, 2020

Replaced the Humidity sensor, Thermistor and door switches. I replaced these thinking the problem was one of the items but didn't want to trial and error one part at a time. Plus the cost was reasonable so if these didn't help I wasn't out a lot of money. I sense the door switch was the problem. Replaced all items and the microwave works great. Thanks for the advice and the cost of the parts. Read more

Thermostat (Microwave)
Genuine Lg part
By: Lg
Part Number: 6930W1A003D

This thermostat is a temperature-sensitive safety switch used in LG microwaves. It monitors internal temperature and opens the circuit when overheating is detected to help protect components from heat damage.

  • Monitors temperature at its mounting location inside the microwave
  • Opens on overtemperature to interrupt power for safety
  • Depending on model/location, a failed or open thermostat can cause no heat, the unit shutting off mid-cycle, or no power until it cools
  • Helps prevent damage to the magnetron, cavity, and wiring due to overheating
What's included: 1 thermostat Install notes:
  • Unplug the microwave before service; the high-voltage capacitor can retain a dangerous charge
  • Note wire positions, remove mounting screws, and install the new thermostat flat against the surface for proper heat sensing
  • Reassemble and test; ensure vents and filters are clear to maintain proper airflow and prevent future overheating

Thermistor (Temperature Sensor)
Genuine Lg part
By: Lg
Part Number: 6322W2A001A

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

  • Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
  • Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
  • Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
  • Use when the existing sensor fails to report correct temperatures or the part number matches.
What's included: One thermistor sensor. Install notes:
  • Always disconnect power to the appliance before servicing to avoid shock or damage.
  • The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
  • Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.
