The AF error on Maytag dryers is caused by a significant restriction in the exhaust airflow, which prevents the appliance from venting hot, moist air efficiently. This Maytag Dryer AF Error Airflow Restricted Fix guide provides a comprehensive approach to troubleshooting and resolving the issue.

Maytag Dryer AF Error Airflow Restricted Fix: Step-by-Step Guide
Airflow restriction is a common issue that can lead to longer drying times and potential fire hazards. When the internal sensors detect that air is not moving at the required velocity, the control board triggers the AF code to protect the machine. Follow the systematic steps below to clear the blockage and reset your dryer.
| Step | Action | Tools Needed |
|---|---|---|
| 1 | Thoroughly clean the lint filter and vacuum the filter housing. | Vacuum, Lint Brush |
| 2 | Inspect the exhaust hose behind the dryer for kinks or crushing. | None |
| 3 | Check the exterior vent hood for lint buildup or bird nests. | Gloves, Ladder |
| 4 | Perform a deep clean of the entire wall ducting system. | Vent Cleaning Kit |
| 5 | Test the thermistor resistance if the code persists after cleaning. | Multimeter |
If your dryer is heating correctly and clothes are drying, but the code remains, the sensor might be overly sensitive. However, you must prioritize physical cleaning to ensure safety and efficiency. Understanding how to fix Maytag dryer error F01 can also help in diagnosing related control board issues.

If physical cleaning does not resolve the AF code, you may need to replace the exhaust thermistor. Always verify your specific model number before purchasing parts to ensure compatibility. A faulty thermistor can send incorrect temperature data, causing the dryer to falsely report restricted airflow.
Exhaust Thermistor
The thermistor monitors the temperature of the air leaving the drum. If it fails or goes out of calibration, it may trigger the AF error even if the vents are completely clear.
Dryer Vent Cleaning Kit
A professional-grade cleaning kit allows you to reach deep into the wall ducts. Regular maintenance with these tools prevents lint accumulation and reduces the risk of dryer fires.
FAQ
Can I still use my dryer with an AF code?
While the dryer may still run, it is not recommended because restricted airflow increases the risk of a lint fire. Additionally, the dryer will take much longer to dry clothes, wasting energy and stressing the heating element.
How do I reset the AF error on my Maytag dryer?
In most cases, the error will clear itself once the airflow restriction is removed and a new cycle is started. If it persists, try unplugging the dryer for one minute to reset the control board.
What if my vents are clear but the AF code remains?
If the venting system is verified to be clear, the issue is likely a faulty exhaust thermistor or a failing control board. Use a multimeter to check the thermistor’s resistance against the manufacturer’s specifications.
