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
- Turn off oven and disconnect power at breaker/circuit.
- Wait 5–10 minutes and restore power to see if error clears.
- Observe whether F2 reappears before attempting further actions.
Technician Only Test and replace oven temperature sensor
- Disconnect power and remove rear panel to access temperature sensor.
- Use a multimeter to measure resistance; at room temp expected ~1080 Ω.
- Replace sensor if reading is far outside expected range or shows open/short condition.
- Reassemble and test oven operation.
Parts needed: Oven temperature sensor (thermistor), Multimeter for testing
Technician Only Inspect and repair wiring harness
- Disconnect power and inspect wiring from sensor to control board.
- Look for damaged insulation, chafed wires, or shorts to chassis.
- Repair or replace wiring harness as needed.
- 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
- Verify sensor and wiring are functional; if F2 persists, test control board temperature circuit.
- Replace control board if diagnostics confirm controller fault.
- Reprogram or configure board per model instructions if required.
Parts needed: Oven control board
- 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
