What F2 means

On GE and Profile microwaves, including over-the-range and countertop models such as the JVM3160, JVM7195, JES1657 and PVM9179 series, F2 means the thermal sensor is shorted. Where F1 describes an open sensor circuit, F2 reads the same sensor as bridged. The control cannot get a reliable temperature, so it may stop heating. You will see F2 on the display and the microwave may refuse to run. The code names the circuit state only and does not prove which part needs attention.

Common causes of F2

  • Thermal sensor circuit shorted
  • Sensor wiring pinched or damaged
  • Connector corroded or damp
  • Control board misreading the sensor
✓ One safe check you can try

1. Open the door and let the microwave rest for a few minutes. 2. Make sure the vents and intake are clear. 3. Switch off the circuit breaker or fuse for 30 seconds and turn it back on. 4. Heat a cup of water briefly as a test. 5. If F2 returns, schedule service.

! Why to stop there
  • A reset does not fix a shorted sensor or damaged wiring.
  • We test the circuit before replacing a sensor or board.
  • The price is in writing before we begin.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F2F2 questions
What is F2 telling me on my GE microwave?

The thermal sensor is shorted. The control cannot read the cavity temperature correctly, so it limits operation until the circuit is checked. Heating may stop altogether.

How is F2 different from F1?

F1 is a thermal sensor circuit that is open, while F2 is one that is shorted. Both involve the same sensor, and both need testing. The repair path differs only after testing.

Should I use the microwave after F2?

Not if the code returns after the breaker reset. The thermal sensor protects the oven from overheating, so wait for a technician. Running without that protection is not worth the risk.
