Why Does My Dryer Say AF

Why Does My Dryer Say AF?

If you have ever encountered the error code “AF” on your dryer’s display panel, you may be wondering what it means and why it is appearing. The AF error code is a common issue that many dryer owners face, and it can be easily resolved in most cases. In this article, we will explore the reasons behind the AF error code and provide some troubleshooting tips to help you get your dryer back up and running efficiently.

What Does AF Mean on a Dryer?

AF stands for “Air Flow,” and when this error code appears on your dryer, it indicates a problem with the ventilation system. Dryers need proper airflow to dry clothes effectively and prevent overheating. When the airflow is restricted, the dryer may not function optimally, and the AF error code is displayed as a warning.

What Causes the AF Error Code?

Several factors can contribute to the AF error code appearing on your dryer. Here are some common causes:

1. Clogged Venting System: The most frequent reason for the AF error code is a clogged venting system. Over time, lint, debris, and even small animals can accumulate in the dryer vent, obstructing the airflow. This restricted airflow triggers the error code.

2. Long Venting Run: If your dryer is located far from an exterior wall, it may require a longer venting run. Longer venting runs increase the likelihood of airflow restrictions, leading to the AF error code.

3. Venting System Design: The way your venting system is designed can also impact the airflow. Sharp bends or excessive twists in the venting system can hinder proper air circulation, triggering the error code.

4. Damaged or Crushed Vent Hose: A damaged or crushed vent hose can restrict the airflow, causing the dryer to display the AF error code.

How to Troubleshoot the AF Error Code:

Now that we understand the causes, let’s explore some troubleshooting steps to fix the AF error code:

1. Check the Venting System: Start inspecting the venting system for any blockages or obstructions. Disconnect the vent hose from the dryer and remove any lint or debris. Additionally, ensure that the exterior vent is clear of any obstructions.

2. Clean the Vent Hose: If the vent hose is clogged, clean it thoroughly using a vent brush or a vacuum cleaner. Pay attention to the bends and twists in the hose to ensure proper airflow.

3. Replace the Vent Hose: If the vent hose is damaged or crushed, it may need to be replaced. Ensure that the replacement hose is the correct size and length for your dryer.

4. Check for Bends or Twists: Inspect the venting system for any sharp bends or excessive twists. If any are present, consider reconfiguring the venting system to provide a smoother airflow path.

5. Shorten the Venting Run: If your dryer has an excessively long venting run, consider shortening it if possible. Reducing the length of the vent hose can improve airflow and prevent the AF error code from appearing.


Q: How often should I clean my dryer vent?

A: It is recommended to clean your dryer vent at least once a year to prevent lint buildup and ensure proper airflow.

Q: Can I use my dryer with the AF error code displayed?

A: It is not recommended to use your dryer when the AF error code is displayed. Restricted airflow can lead to overheating and potential fire hazards.

Q: Can I clear the AF error code simply resetting the dryer?

A: While resetting the dryer may temporarily clear the error code, it is crucial to address the underlying issue causing the restriction in airflow. Resetting alone will not solve the problem.

Q: Should I hire a professional to fix the AF error code?

A: If you are unsure about troubleshooting or if the issue persists after attempting the suggested solutions, it is advisable to seek professional assistance to ensure the proper repair and maintenance of your dryer.

In conclusion, the AF error code on your dryer indicates a restricted airflow issue. By following the troubleshooting steps mentioned above, you can resolve the problem and prevent further complications. Regularly maintaining your dryer’s venting system is crucial to ensure optimal performance and safety.
