Maytag bravos xl dryer not drying — new house with roof exhaust vent · af

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Photograph the display and record the complete Maytag model number, gas or electric type, selected cycle, load condition, and whether AF appears during sensing, while drying, or after a long cycle. Confirm that the message is AF or Check Vent rather than F4E3 or another code.

   Expected result: AF is confirmed on a Maytag Bravos XL, or the exact display and model are uncertain.

   Next step: If AF is confirmed, continue with the external airflow checks. If the display differs or the model cannot be matched, use the exact owner guide before applying this path.

   Why this matters

   Why: Maytag maps AF and F4E3 to restricted airflow, while other dryer codes use different branches. The exact model and display must stay together before changing the vent or ordering any part.

2. Check 2

   With the dryer off and cool, clean the lint screen and inspect the accessible duct from the dryer outlet to the wall for lint, crushing, kinks, sagging, foil or plastic material, and an overly long or sharply turned section. Do not run the dryer without the screen or reach into the cabinet.

   Expected result: The screen or short duct is blocked, damaged, sharply bent, or visibly clear.

   Next step: Remove only loose accessible lint and correct an obvious external kink without opening the dryer. If the accessible path is clear, move the diagnosis to the roof termination and full-house vent run.

   Why this matters

   Why: Maytag identifies a clogged screen or vent and a crushed, kinked, or over-turned run as direct AF causes. A clear short section does not rule out a restriction in the concealed roof run.

3. Check 3

   From ground level or another safe, non-roof position, inspect the visible roof exhaust termination for a blocked hood, lint, leaves, bird or rodent nesting, a screen that traps lint, or a cap that cannot open freely. Do not climb onto the roof, remove roofing components, or insert a tool into the concealed duct.

   Expected result: The roof outlet is obstructed or screened, the flap or hood cannot open freely, the termination cannot be safely seen, or it appears clear.

   Next step: If an obstruction is safely reachable from the ground, remove only loose external debris. For a roof-level, concealed, screened, or uncertain termination, arrange professional vent inspection and cleaning rather than attempting a roof repair.

   Why this matters

   Why: Maytag says lint and debris at the exhaust hood or roof cap can restrict the path, and its roof-vent instructions warn against screening or capping the end in the wrong configuration. An apparently clear cap does not prove that the vertical run is clean.

4. Check 4

   If there is no heat, humidity or lint discharge at the safe exterior outlet, run a short heated timed cycle only if the dryer has no smoke, burning smell, extreme heat, leak, or electrical symptom; otherwise leave it off. Note whether airflow is weak and whether AF returns after the accessible checks.

   Expected result: The outside airflow is weak or absent, clothing remains warm but damp, the laundry area becomes humid, or AF clears and drying returns to normal.

   Next step: If airflow remains weak or AF returns, stop using the dryer and have the entire roof run measured, cleaned, and checked against the model installation instructions by a venting specialist. If performance returns, continue cleaning the screen before every load and monitor the next cycles.

   Why this matters

   Why: Maytag associates weak exhaust movement, warm damp loads, and elevated laundry-room humidity with restricted venting. Clearing AF after a local correction makes that condition more likely, but it does not prove the concealed roof run is safe.
