LG Oven Error Code F-31: How to Fix It

Q: What causes LG oven error code F-31?

Error code F-31 is caused by a short circuit in the oven temperature sensor. This can result from sensor failure due to age, moisture exposure, or physical damage from cleaning chemicals or extreme heat cycles.

Q: Can I still use my LG oven with error code F-31?

No, you cannot use your oven when error code F-31 appears. The oven will not heat as a safety measure because it cannot properly monitor internal temperature without a functioning sensor.

Q: How much does it cost to fix LG oven error F-31?

A replacement oven temperature sensor typically costs $15-40. Professional repair service ranges from $150-250 including parts and labor. DIY repair can save significant money if you're comfortable with basic electrical work.

Q: How long do LG oven temperature sensors last?

LG oven temperature sensors typically last 8-12 years with normal use. Heavy use, frequent self-cleaning cycles, or exposure to harsh cleaning chemicals can reduce sensor lifespan.

Q: Will unplugging my LG oven clear error code F-31?

Unplugging the oven will temporarily clear the error code from the display, but the F-31 error will return when you try to use the oven if the underlying sensor short circuit hasn't been repaired.

Abstract

LG oven error code F-31 indicates a short circuit in the oven temperature sensor. This safety feature prevents your oven from operating when the sensor cannot properly read internal temperatures, which could lead to overheating or undercooked food.
