What Does Goodman Error Code EAF Mean?
The 'EAF' error code on your Goodman furnace indicates an Airflow Error. Your furnace's control board monitors the air pressure inside the unit using a pressure switch. If the furnace doesn't detect enough airflow when the blower motor is running, it assumes there's a blockage or a problem with the blower itself. To protect the furnace from overheating or other damage, it shuts down and displays the EAF error. This error is important because insufficient airflow can lead to the furnace overheating, which can damage components like the heat exchanger. A cracked heat exchanger can leak dangerous carbon monoxide into your home. While this code doesn't guarantee a cracked heat exchanger, it's important to address the airflow issue promptly to prevent further problems.
Common Causes of Goodman Code EAF
- Dirty air filter restricting airflow.
- Blocked return air grilles or supply registers.
