LG Microwave Error Code F-1: How to Fix It

Q: What does error code F-1 mean on an LG microwave?

Error code F-1 on an LG microwave indicates a cavity temperature sensor failure. The sensor that monitors internal temperature is either faulty, disconnected, or providing incorrect readings to the control board.

Q: Is it safe to use my LG microwave with error code F-1?

No, you should not use your microwave with error code F-1. A faulty temperature sensor can cause overheating, inadequate cooking, or potential safety hazards. Stop using the microwave until the issue is resolved.

Q: How much does it cost to fix LG microwave error F-1?

The temperature sensor part typically costs $15-40, plus $100-200 for professional repair labor. DIY repair can save on labor costs but requires technical skills and safety precautions when working with microwave components.

Q: Can I reset my LG microwave to clear error code F-1?

While you can try unplugging the microwave for 10 minutes to reset the control board, error code F-1 indicates a hardware failure that won't be resolved by a simple reset. The temperature sensor will likely need replacement.

Q: How long does an LG microwave temperature sensor last?

LG microwave temperature sensors typically last 5-10 years depending on usage frequency and cooking habits. Frequent use of high-temperature settings or steam cooking can potentially shorten sensor lifespan.

Abstract

LG microwave error code F-1 indicates a cavity temperature sensor failure, which means your microwave cannot properly monitor internal temperature. This is a high-severity error that can prevent your microwave from operating safely and may cause overheating or inadequate cooking.
