What Does Error F2 Mean?

The LG oven F2 error indicates a malfunction with the temperature sensor, often leading to inaccurate temperature readings and inconsistent cooking results. This error may occur due to a short in the oven temperature sensor, wiring issues between the sensor and the control board, or a fault within the control board's temperature circuit. Symptoms include the F2 code on the control panel, the oven shutting off unexpectedly, beeping sounds, and incorrect temperature regulation.

Common Symptoms:

  • F2 displayed on oven control panel
  • Oven may shut off mid-cycle or refuse to heat
  • Possible beeping when error appears
  • Temperature may not regulate correctly

Possible Causes

  • Oven temperature sensor short or faulty (medium)
  • Wiring issue between temperature sensor and control board (medium)
  • Stuck relay or control board temperature circuit issue (low)

How to Fix Error F2

DIY Fix Power reset and basic check

  1. Turn off oven and disconnect power at breaker/circuit.
  2. Wait 5–10 minutes and restore power to see if error clears.
  3. Observe whether F2 reappears before attempting further actions.

Technician Only Test and replace oven temperature sensor

  1. Disconnect power and remove rear panel to access temperature sensor.
  2. Use a multimeter to measure resistance; at room temp expected ~1080 Ω.
  3. Replace sensor if reading is far outside expected range or shows open/short condition.
  4. Reassemble and test oven operation.

Parts needed: Oven temperature sensor (thermistor), Multimeter for testing

Technician Only Inspect and repair wiring harness

  1. Disconnect power and inspect wiring from sensor to control board.
  2. Look for damaged insulation, chafed wires, or shorts to chassis.
  3. Repair or replace wiring harness as needed.
  4. Verify secure connections at sensor and control board.

Parts needed: Wiring harness or individual wire repair/insulation materials

Technician Only Control board diagnosis and replacement

  1. Verify sensor and wiring are functional; if F2 persists, test control board temperature circuit.
  2. Replace control board if diagnostics confirm controller fault.
  3. Reprogram or configure board per model instructions if required.

Parts needed: Oven control board

🛑 When to Call a Pro:
  • If error persists after resetting and basic checks
  • If you are uncomfortable working with electrical components or internal oven parts
  • If control board diagnostics indicate complex electronics fault
