What Does Error F25 Mean?
The LG oven F25 error code indicates a malfunction in the steam thermistor, causing erratic temperature readings and inconsistent cooking performance. This issue often arises during or after using the steam function, leading to improper oven operation and failure to maintain the correct temperature. If the error persists, it's crucial to inspect the steam thermistor circuit and associated components.
Common Symptoms:
- F25 displayed on control panel during or after using steam function
- Steam or oven may function improperly or fail to maintain correct temperature
Possible Causes
- Shorted steam thermistor (steam temperature sensor) (medium)
How to Fix Error F25
DIY Fix Basic checks and reset
- Stop oven operation and turn off the steam function.
- Turn off power to the oven by unplugging or switching off the circuit breaker for a few minutes.
- Restore power and see if F25 persists.
Technician Only Inspect and repair steam thermistor circuit
- Disconnect power to appliance.
- Locate the steam thermistor/temperature sensor and inspect for damage.
- Test sensor resistance with a multimeter (compare to expected spec if available).
- Inspect wiring harness and connectors for damage or loose connections.
- Replace the steam thermistor if it tests shorted or outside spec.
- If sensor and wiring are good, inspect control board sensor input circuit.
Parts needed: Steam thermistor (temperature sensor), Connectors/wiring harness, Control board (if needed)
- If error persists after basic reset and visual checks
- If internal components need testing or replacement beyond basic user checks
- If wiring or control board issues are suspected
