What Does Error F2 Mean?

The Kenmore microwave F2 error indicates a malfunction in the thermistor or temperature sensor, causing the microwave to stop heating shortly after starting a cooking cycle. Symptoms include the display of the F2 error code and a lack of heat production. This issue is often accompanied by unusual buzzing sounds. A power reset may temporarily resolve the issue, but persistent F2 errors typically require inspection and possible replacement of the faulty thermistor or related components.

Common Symptoms:

  • Microwave displays F2 during or immediately after starting a cooking cycle
  • Microwave may stop heating shortly after starting
  • No heat produced while F2 is displayed

Possible Causes

  • Thermistor/Temperature sensor shorted or failed (medium)

How to Fix Error F2

DIY Fix Power reset and symptom check

  1. Unplug the microwave from the power outlet.
  2. Wait 1–2 minutes.
  3. Plug the microwave back in and try a short heating cycle.
  4. See if F2 returns.

Technician Only Inspect & test temperature sensing circuit

  1. Disconnect power and remove microwave outer cabinet.
  2. Locate the cavity thermistor/temperature sensor.
  3. Inspect wiring harness for damage or loose connectors.
  4. Use a multimeter to measure thermistor resistance against specification; a shorted reading suggests failure.
  5. Replace thermistor/temperature sensor if faulty.

Parts needed: Thermistor / temperature sensor, Wiring harness (if damaged)

🛑 When to Call a Pro:
  • If the microwave displays F2 consistently after reset and basic checks
  • If multimeter testing shows unexpected readings in the thermistor circuit
  • If internal inspection reveals damaged wiring
  • If you are not comfortable working around high‑voltage microwave components
