What to Do When Your Furnace Shows an Error Code

Modern furnaces communicate problems through error codes displayed as blinking LED lights. This guide helps you read and respond to error codes safely before calling for professional service.

Immediate Steps to Take

1. Locate the error code display — usually a small glass window on the lower furnace panel showing a blinking LED light. 2. Count the number of short and long blinks — refer to the diagnostic chart on the inside of the furnace panel cover for the code meaning. 3. Write down the error code before calling for service — this information helps your technician arrive prepared with the correct diagnostic approach and parts. 4. Press the reset button once (if your furnace has one) to see if the error clears.

Next Steps

5. For ignition-related error codes, check that the gas supply valve is fully open and the air filter is clean before calling. 6. Call for professional service if the error code cannot be cleared, if it returns after resetting, or if you are unsure what the code means.
