Does your Maytag dryer display an AF error code? This restricted airflow notice signals that air can’t circulate properly to dry your clothes. When airflow in a dryer gets blocked, wet laundry takes forever to dry. Code AF warns that it’s time to check your machine. Lint buildup, clogged vents, or crushed ductwork are common causes that hamper airflow. Left unfixed, poor ventilation strains the dryer and wastes energy over time. Fortunately, a few DIY steps can solve most AF issues. Read on to learn what triggers code AF in a Maytag dryer and how to troubleshoot and resolve airflow restrictions for faster, more efficient drying.
Understanding Error Code AF
The code AF on your Maytag dryer stands for “Restricted Air Flow.” This simply means there is not enough air moving through your dryer. Air needs to flow freely for your dryer to work its best.
Why does the AF error code matter?
When AF pops up, it’s telling you there’s not enough airflow. This could make your clothes take way too long to dry. It also wastes energy. Poor airflow can even damage your dryer over time. So, AF is an important warning sign to address.
How does poor airflow impact drying?
Your dryer needs open airways. When airflow is restricted, it can’t run hot enough or circulate air through the clothes well. Wet clothes tumble in weak heat, and the air will dry more slowly. The lack of airflow also reduces your dryer’s efficiency. It has to work harder and use more energy to dry each load.
Why fix AF issues right away?
You want your dryer to last, right? Letting AF issues go leads to strain on the machine. Parts wear out faster. Failure or fires become more likely over time. But catch and fix airflow problems early, and your dryer will hum along for years trouble-free. Regular airflow ensures the dryer runs smoother and lasts longer.
What Causes the AF Error Code?
Let’s look at the most common reasons you might see the restricted airflow code pop up:
Clogged Lint Screen
Over time, lint from your clothes can build up on the screen. If it gets totally caked with lint, no air gets through! This is probably the first thing to check when AF appears.
Got lint? It’s an airflow blocker. Cleaning the lint screen after each load keeps air moving freely.
Blocked Vent System
Lint can stick to the vent and ductwork too. Enough buildup starts blocking airflow from exiting your dryer. Lint, dust, toys, socks – anything in the vent system hampers proper venting.
Watch out – a blocked vent is a fire hazard! Cleaning the system regularly avoids this risk.
Wrong Vent Installation
Was your dryer vent installed incorrectly? Kinks in the ductwork or connections that came loose restrict airflow. Tight bends or cramped vents also cause poor ventilation.
Proper venting on install prevents AF codes down the road.
Crushed or Kinked Ductwork
Over time, ductwork can get bent out of shape or flattened. This crunches the airflow path. Damaged or sagging ducts should be repaired right away.
Maintaining duct integrity ensures strong airflow and drying power.
Faulty Interior Parts
Sometimes, AF means an internal part is broken. If the lint screen and venting check out OK, a bad thermal fuse or blower motor could be the issue. This may require a repair call.
Diagnosing internal parts is tricky. When external issues are ruled out, it’s time to contact a pro.
Fixing the AF Code – Step-by-Step
Let’s walk through how to troubleshoot and solve airflow restrictions triggering the AF code.
Clean the Lint Screen
The lint filter is the first thing to check.
- Unplug the dryer for safety.
- Pull out the lint screen and brush it off. For caked-on lint, hold it under running water or use a nylon brush.
- Replace the screen when it’s 100% clean. Double-check that no lint remains.
Don’t skip lint screen cleaning! This simple step avoids many AF code headaches.
Inspect and Clean the Exhaust Vent
Vent buildup also causes restricted airflow.
- Unplug the dryer and pull it out from the wall.
- Detach the vent from the dryer. Inspect the vent opening and ductwork for any debris inside.
- Use a vacuum hose to clear any lint in the system.
- Reattach the vent once it has fully cleared of lint.
Doing a periodic deep clean of the full vent system prevents AF issues.
Confirm No Blockages in Venting
Don’t stop at the back vent opening.
- Remove vent covers to check for lint along the full run of ductwork.
- Vacuum any lint or debris found.
- Ensure the covers are sealed tightly when replaced.
Scan the entire venting path to catch any sneaky airflow blocks.
Check Venting Setup
Improper venting can also trigger an AF code.
- Use rigid metal ductwork, not plastic.
- Remove extra turns or bends in the duct run.
- Detach sagging sections and support properly.
- Seal all connections with duct tape.
Straight solid ducting keeps air flowing freely.
Confirm No Airflow Obstructions
Lastly, verify that there are no issues outside or inside the dryer.
Outside: Make sure the external vent flap opens properly, and no debris is blocking it.
Inside: Service the dryer if the lint screen and venting checks don’t reveal the issue. Internal parts like the thermal fuse may need replacement.
Doing a full inspection inside and out will get to the bottom of any AF causes. Just follow these troubleshooting steps to keep your Maytag airflow restriction-free.
Avoiding AF Codes Going Forward
Don’t want to keep seeing code AF pop up? Here are some tips to prevent airflow restrictions for good:
A. Clean the Lint Screen Regularly
The #1 cause of AF codes is lint buildup. Get into a routine:
- Clean the lint screen after every single load. No exceptions!
- Wipe the screen thoroughly with a brush or damp cloth.
- Check the seal and replace screens with tears or gaps.
Staying on top of lint screen care avoids so many issues down the road.
B. Avoid Overloading the Dryer
It’s tempting to cram it fully packed, but overloading causes problems:
- Too many clothes restrict airflow. This triggers AF codes.
- The dryer has to work extra hard and run longer. This wastes energy.
- Wet spots in the middle take forever to dry.
Match the load to your dryer’s capacity for ideal airflow and drying.
C. Inspect Ductwork and Venting Yearly
Lint and debris accumulate over time. To stop them before AF happens:
- Vacuum the full duct run from the dryer to the outdoor vent once a year.
- Check for kinks, cracks, or blockages. Repair any issues found.
- Confirm the outdoor vent flap opens properly and seals shut.
Annual dryer vent inspection and cleaning prevent airflow reduction.
D. Ensure Proper Installation
Mistakes in the initial vent setup can come back to haunt you. Insist your dryer gets:
- Smooth-walled rigid metal ductwork.
- A short, straight duct runs through the outdoor vent.
- Tight connections are sealed with aluminum tape, not screws.
Proper installation means great airflow for years.

Conclusion
We’ve covered a lot of ground on Maytag dryer code AF. Let’s recap the key takeaways:
- AF means restricted airflow that hurts drying performance. Don’t ignore it!
- Lint buildup, vent blockages, crushed ducts, or improper venting usually cause AF codes.
- Thoroughly cleaning the lint screen and vent system fixes most AF issues.
- Prevent problems in the first place with regular maintenance and proper loading.
- If you’ve checked everything and AF persists, get a service tech to check internal parts.
Remember – airflow is crucial for your dryer’s health and efficiency. Pay attention when code AF pops up. Following these troubleshooting tips will restore smooth sailing and keep your Maytag happy!
