What Does Error F2 Mean?

The GE microwave F2 error indicates a malfunction in the thermal sensor, often causing the microwave to display the code during or shortly after operation. This may lead to unusual buzzing sounds and a failure to heat food. A shorted thermal sensor is the primary cause, but wiring issues or a defective control board could also be responsible. Immediate troubleshooting includes performing a basic reset by unplugging the microwave for 1-2 minutes and ensuring the cavity is clean and dry.

Common Symptoms:

  • F2 appears on display during or shortly after operation
  • Microwave may refuse to start or operate normally while F2 is displayed

Possible Causes

  • Shorted thermal sensor (temperature sensor) (high)
  • Wiring issue between temperature sensor and control board (medium)
  • Defective control board misinterpreting sensor signal (medium)

How to Fix Error F2

DIY Fix Basic reset and initial checks

  1. Unplug the microwave from the power outlet and wait 1–2 minutes.
  2. Plug the microwave back in and see if the F2 code reappears.
  3. Ensure the microwave’s cavity is clean and dry, with no moisture or debris near sensor areas.

Technician Only Diagnose and repair temperature sensor issue

  1. Disconnect power and discharge high-voltage components safely.
  2. Locate and inspect the temperature sensor (thermal sensor) for signs of damage or short.
  3. Check wiring harness and connectors between sensor and control board for damage or shorts.
  4. Test temperature sensor resistance with a multimeter according to service specifications.
  5. Replace faulty sensor or repair wiring as needed.
  6. Verify proper operation and that F2 error is cleared.

Parts needed: Temperature (thermal) sensor, Wiring harness/connectors, Control board (if necessary)

🛑 When to Call a Pro:
  • If the F2 code persists after basic reset and cleaning
  • If you are not trained in microwave electronics safety (high-voltage risks)
  • If internal inspection reveals burned wiring, connectors, or control board damage
