Amana Dryer Error Code AF

The AF code on an Amana dryer stands for low inlet air flow. It means the dryer has detected that exhaust airflow is restricted below an acceptable level. This is commonly caused by a crushed vent duct, a clogged vent run, or a blocked exterior vent cap. Amana's built-in diagnostic routine called Displaying Inlet Air Flow can help confirm the severity of the restriction.

It is not recommended to continue running the dryer while the AF code is active. Restricted airflow causes heat to build up inside the dryer, which can lead to overheating, longer drying times, and in serious cases, a fire hazard. Address the vent restriction before resuming normal use.

If the fix is simply cleaning out lint from the vent run or straightening a kinked duct, the cost may be minimal or nothing at all. Replacing a damaged transition duct typically costs between $10 and $30 for parts if done yourself. If a professional appliance technician or duct cleaning service is needed, expect to pay anywhere from $75 to $200 depending on the complexity of the vent run and local labor rates.

Start by pulling the dryer away from the wall and inspecting the flexible transition duct for any crushing or kinking. If the duct looks damaged, replace it with rigid or semi-rigid metal duct. Also check the full vent run to the exterior of the home for lint buildup and make sure the exterior vent cap opens freely. After making corrections, run the Displaying Inlet Air Flow diagnostic to confirm airflow has returned to an acceptable level.

Simply resetting or power cycling the dryer will not permanently clear the AF code if the underlying airflow restriction is still present. The code will return once the dryer runs and detects low airflow again. The vent path must be corrected first, and then the diagnostic routine should be used to confirm the issue is resolved.
