LG Oven Error Code F-30: How to Fix It

Q: Can I still use my LG oven with error code F-30?

No, you should not use the oven with error F-30. The faulty temperature sensor means the oven cannot properly regulate heat, which could lead to overcooking, undercooking, or potential safety hazards.

Q: How much does an LG oven temperature sensor cost?

LG oven temperature sensors typically cost between $25-$60, depending on your specific model. Generic replacement sensors may be less expensive but ensure compatibility with your oven model.

Q: What causes LG oven temperature sensors to fail?

Temperature sensors commonly fail due to normal wear over time, exposure to high heat, corrosion from oven cleaning chemicals, or physical damage from oven racks or cookware bumping against them.

Q: How do I know if the problem is the sensor or the control board?

Test the sensor with a multimeter first. If it reads the correct resistance (1,080-1,090 ohms) and connections are secure, the issue may be with the control board, which requires professional diagnosis.

Q: Will clearing the error code fix the F-30 problem?

No, simply clearing or resetting the error code will not fix the underlying sensor problem. The F-30 error will return until you repair or replace the faulty temperature sensor.

Abstract

LG oven error code F-30 appears when the temperature sensor probe is disconnected or malfunctioning. This sensor monitors oven temperature and sends readings to the control board, so when it fails, your oven can't regulate heat properly.
