Amana Dryer Error Codes: Complete Diagnosis & Fix Guide

Common Symptoms

• Error code displayed on control panel (AF, L2, F01, F22, F26, F28, F30, etc.)
• Dryer stops mid-cycle and displays a code with beeping
• Drum tumbles but heating stops and a code appears
• Dryer won't start and displays a fault code
• Clothes remain damp and a heat-related error is displayed
• Control panel locks up with an error and won't respond to button presses

Most Likely Causes

1. 1

   AF — Airflow Restricted (Most Common — and Free to Fix)

   The AF code means the dryer's airflow sensor or outlet thermistor detected restricted exhaust air movement. The root cause is almost always a clogged lint exhaust duct. On Amana electric and gas dryers, exhaust restriction causes the dryer to overheat, triggering the AF fault before the thermal fuse blows. Clear the complete duct from the dryer exhaust port to the exterior cap. Also check that the flexible duct behind the dryer is not kinked or crushed, and that the exterior cap damper flap opens freely during operation.

2. 2

   F22 — Outlet Thermistor / Thermal Fuse Circuit Open

   F22 indicates the control board detected an open circuit in the outlet thermistor or thermal fuse. On most Amana dryer models, the outlet thermistor and thermal fuse are located on the exhaust duct inside the cabinet — test each component for continuity. A blown thermal fuse (no continuity) is the most common trigger. Always clean the exhaust vent after replacing the thermal fuse or F22 will return immediately.

3. 3

   F30 — Restricted Airflow (Sensor-Triggered Variant)

   F30 is a sensor-triggered airflow restriction code that appears on models with an electronic moisture sensing system. Unlike AF (which may appear mid-cycle), F30 often appears at the start of the cycle when the control board performs a pre-cycle airflow check. The fix is identical to AF: clear the exhaust duct, clean the lint filter, and verify the exterior cap opens freely.

4. 4

   L2 — Low Voltage / Leg 2 Missing (Electric Dryers)

   L2 means the control board detected that one of the two 120V legs of the 240V supply is absent. Electric dryers require a full 240V circuit (two 120V legs). L2 appears when a circuit breaker has tripped on only one leg — common when a dryer circuit breaker trips halfway. Go to the electrical panel, turn the dryer breaker fully OFF, then back ON. If L2 returns, the breaker has failed and needs replacement by an electrician. Never operate a 240V dryer on a partially-failed circuit.

5. 5

   F01 — Main Control Board Communication Fault

   F01 indicates an internal communication error on the main electronic control board. It can appear after a power surge or as the control board begins to fail. First, perform a hard reset: unplug the dryer for 5 full minutes, then restore power. If F01 returns within one cycle, the control board likely needs replacement. Amana/Whirlpool control boards for common models cost $50–$150 and are DIY-replaceable with basic tools.

6. 6

   F26 — Motor Relay Fault

   F26 indicates the control board detected a problem with the motor relay — the component that switches power to the drive motor. It can signal a failing relay on the control board, a seized motor that draws excess current, or a wiring harness fault between the board and motor. Start by testing the motor wiring harness connections. If the harness is intact, attempt a drive motor resistance test: disconnect the motor leads and measure across the motor terminals — a healthy motor reads approximately 1–4 ohms. OL = failed motor windings.

7. 7

   F28 — Moisture Sensor Bar Open or Short

   F28 indicates a problem with the moisture sensing bars inside the drum — the two small metal strips that detect residual moisture in clothes. The bars become coated with fabric softener residue over time, causing them to read incorrectly. Clean the moisture sensor bars with rubbing alcohol on a cotton ball. If F28 persists after cleaning, disconnect the sensor wiring harness and test continuity across the sensor leads to check for a wiring break.

Quick DIY Checks

1. 1Step 1 — Hard reset (always start here): Unplug the Amana dryer from the wall outlet. Wait 5 full minutes. Reconnect power and attempt to restart a cycle. This clears many transient fault codes — especially F01 and F26 — that were triggered by a momentary power fluctuation. If the code returns within one cycle, proceed with the specific checks below.
2. 2Step 2 — For AF or F30 (airflow): Unplug the dryer. Disconnect the flexible exhaust hose at the back of the unit and check for lint blockage at the dryer exhaust port. Use a flexible dryer vent brush kit to clean the full duct run from the dryer to the exterior wall cap. While cleaning, push the exterior cap damper flap from outside — it should open freely with light finger pressure. A damper that sticks closed or only partially opens will trigger AF. Also clean the lint screen housing: remove the lint screen and use a long vacuum attachment to remove lint from inside the housing slot.
3. 3Step 3 — For F22 (thermistor / thermal fuse): Unplug the dryer. Remove the back panel (4–6 Phillips screws). Locate the thermal fuse and outlet thermistor on the exhaust duct housing — both are small components with two spade-terminal wires. Disconnect each component individually and test continuity with a multimeter set to continuity mode (audible beep). The thermal fuse must beep (continuity present). No beep = blown fuse — replace part 63196 or DC47-00018A depending on your Amana model. The outlet thermistor should show resistance (approximately 10kΩ at room temperature); OL = failed thermistor, replace it.

Repair vs Replace

Recommended Tools & Parts

• Thermal Fuse — Part 63196 / DC47-00018A

  One-time safety thermal fuse for Amana dryers — the primary replacement for an F22 code. Verify part number with your model: older Amana models use 63196, newer Samsung-platform models use DC47-00018A.
