What Does Error F6 Mean?
The LG oven F6 error indicates an over-temperature condition, where the oven temperature exceeds safe limits, potentially causing erratic cooking results. This can occur due to a faulty temperature sensor or thermistor, wiring issues, or the oven reaching temperatures above 650°F. If this error appears, the oven may shut down or operate abnormally. Immediate action includes turning off the oven and allowing it to cool down to prevent further damage.
Common Symptoms:
- Oven displays F6 during or after heating cycles
- Oven shuts down or won’t operate normally after code appears
- Code appears when oven reaches or attempts to exceed high temperatures
Possible Causes
- Oven temperature exceeding safe threshold (overheat) (medium)
- Faulty temperature sensor or thermistor (medium)
- Wiring or connection issue between temperature sensor and control board (medium)
How to Fix Error F6
DIY Fix Immediate checks and reset
- Stop oven use when F6 appears
- Turn oven off and allow to cool completely
- Turn power off at breaker for a few minutes then restore to clear any transient errors
- Ensure oven is not in self‑clean mode during normal cooking
Technician Only Diagnose and repair sensor and high temperature triggers
- Disconnect power to oven
- Access and test oven temperature sensor resistance with a multimeter
- Inspect wiring harness between sensor and control board for damage
- Replace temperature sensor if out of range or visibly damaged
- If sensor and wiring are OK, inspect control board for faults and replace if needed
Parts needed: Oven temperature sensor, Wiring harness, Control board
- If oven repeatedly overheats or F6 persists after basic reset
- If any wiring appears charred or unsafe to handle
- If temperature sensor tests normal but issue remains
