Whirlpool Dryer Error Codes: Complete List with Fixes

Whirlpool dryers use the same F/E error code system as Whirlpool washers — a fault category (F1, F2, F3, etc.) combined with a specific fault number (E1, E2, E3). This system is shared across Maytag, KitchenAid, Amana, and Jenn-Air dryers. Additionally, Whirlpool dryers have unique codes like "AF" (restricted airflow) and "L2" (low voltage) that address dryer-specific safety concerns. This guide covers every code for both electric and gas Whirlpool dryers, with model-specific detail for the WED/WGD (current), Cabrio, and Duet platforms.

How Whirlpool Dryer Error Codes Work

The F/E system categories for dryers:

• F1: Main control board errors
• F2: User interface / stuck key errors
• F3: Sensor errors (thermistors — exhaust, inlet, moisture)
• F4: Heating system errors (element relay, gas valve relay)
• F6: Communication errors between boards

Dryer-specific standalone codes:

• AF: Restricted airflow (safety alert)
• L2: Low line voltage (240V issue on electric dryers)

Electric vs. Gas differences: Electric dryers use a heating element controlled by a relay (F4E1), while gas dryers use gas valve solenoid coils controlled by a separate relay (F4E3). All other codes apply to both types.

Before troubleshooting: Unplug the dryer (electric) or turn off gas and unplug (gas dryer), wait 5 minutes, restore power, and run a timed dry cycle. If the code returns, proceed with detailed diagnosis below.

F1E1 — Main Control Board Error

The main electronic control board has an internal failure. This is a high-severity code that almost always requires board replacement.

Common causes:

• Power surge damage to the control board (the leading cause in Sacramento Valley — summer electrical storms)
• Component failure on the board: cracked solder joints, blown MOSFETs, swollen capacitors
• Loose or corroded wire harness connections to the board

How to fix:

1. Unplug the dryer for 5 minutes to allow a full board reset. If F1E1 clears and doesn't return, a momentary power surge was the likely cause — install a surge protector.
2. Access the main control board behind the lower access panel (WED/Maytag MED series) or inside the console.
3. Inspect for visible burn marks, cracked solder, or swollen capacitors on the board.
4. Check all wire harness connectors for secure seating and green corrosion on pins.
5. If the board shows damage or the code persists after visual inspection, replace the main control board (W10432257, $150–$280).

Part cost: Main control board W10432257 costs $150–$280. Professional repair runs $250–$420 total.

Warning: Electric dryers operate on 240V. Disconnect power at the breaker panel — not just the plug — before inspecting the control board. Capacitors can hold a dangerous charge for several minutes.

F2E1 — Stuck Key / User Interface Error

A button on the dryer control panel is physically stuck or the user interface board is malfunctioning. The dryer may beep randomly or change settings spontaneously.

Common causes:

• Lint and detergent residue buildup around buttons
• Heat-warped control panel overlay (membrane) — dryer heat migrates upward through the top panel
• Moisture damage to the UI board from steam
• Failed user interface board (part W11170219)

How to fix:

1. Unplug the dryer and firmly press each button on the control panel several times to free any physically stuck key.
2. Clean around all buttons with a damp cloth to remove lint and residue buildup.
3. Check the control panel overlay for bubbles, warping, or soft spots — on Whirlpool WED7500 and KitchenAid KGDR series, heat from the top panel softens the overlay adhesive.
4. If cleaning doesn't resolve the issue, replace the UI board (W11170219, $75–$180) and the overlay (W11106748, $35–$60) together.

Part cost: UI board W11170219 costs $75–$180. Overlay W11106748 costs $35–$60.

F3E1 — Exhaust Thermistor Error

The exhaust temperature sensor (thermistor) is reading an out-of-range value. The AccuDry sensor system uses this to modulate heat output and cycle timing.

Common causes:

• Failed exhaust thermistor (part WP8577274)
• Restricted dryer vent causing thermistor overheating and premature failure
• Disconnected or damaged thermistor wiring
• Sacramento homes with long vent runs (>15 feet) see accelerated thermistor degradation

How to fix:

1. Check the vent system first. A restricted vent overheats the thermistor and causes premature failure. Clean the full vent path from dryer to exterior wall cap. Ensure the run is not longer than 25 feet equivalent (subtract 5 feet for each 90-degree elbow).
2. Locate the exhaust thermistor on the blower housing or exhaust duct inside the dryer.
3. Disconnect and measure resistance: approximately 10,000 ohms at room temperature (72 degrees F). Apply brief heat — resistance should decrease smoothly. Erratic or no change means a failed sensor.
4. Check the wiring from the thermistor to the main control board for breaks.
5. Replace the thermistor if readings are out of specification (WP8577274, $15–$30).

Part cost: Exhaust thermistor WP8577274 costs $15–$30. Professional repair runs $120–$240 total.

Warning: A shorted exhaust thermistor can allow the dryer to overheat beyond safe limits. If clothes come out extremely hot or you smell burning fabric, stop using the dryer immediately.

F3E2 — Moisture Sensor Error

The AccuDry moisture sensor bars inside the drum are not functioning. Auto-dry cycles will not work correctly.

Common causes:

• Fabric softener sheet residue coating the sensor bars (the #1 cause — accounts for 70% of F3E2 codes)
• Failed moisture sensor bar assembly (part WPW10833859)
• Wiring damage between sensor bars and control board

How to fix:

1. Clean the sensor bars first. Locate the two metal strips inside the drum near the lint screen housing. Clean with fine sandpaper (220 grit) or a cloth soaked in rubbing alcohol. Fabric softener sheets deposit a waxy residue that insulates the bars, making the dryer think clothes are always dry or always wet.
2. Run a diagnostic test: place a damp cloth against the sensor bars while in test mode. The control board should register a resistance change.
3. If cleaning doesn't restore function, test wiring continuity from the sensor bars to the main control board.
4. Replace the sensor assembly only if cleaning and wiring checks fail (WPW10833859, $30–$60).

Part cost: Moisture sensor bars WPW10833859 costs $30–$60. Rubbing alcohol and sandpaper cost under $5.

F3E3 — Inlet Thermistor Error

The inlet temperature sensor monitoring incoming air temperature to the drum has failed. Often appears alongside F3E1 if both sensors are degraded.

Common causes:

• Failed inlet thermistor (mounted on the heater housing or air intake plenum)
• Heat damage to wiring near the heater element assembly
• Overall overheating from restricted vent system

How to fix:

1. If both F3E1 and F3E3 appear together, suspect a restricted vent system causing overall overheating rather than individual sensor failures. Inspect the full vent path before replacing either sensor.
2. Locate the inlet thermistor on the heater housing. Disconnect and measure resistance: approximately 50,000 ohms at room temperature for NTC type.
3. Compare readings between inlet and exhaust thermistors at room temperature — they should be in the same general range for their respective types.
4. Check for heat damage to wiring near the heating element.
5. Replace the thermistor if out of specification (WP8577274, $15–$30).

Part cost: Inlet thermistor WP8577274 costs $15–$30.

Warning: A failed inlet thermistor can disable the high-temperature safety limit. If the dryer exterior becomes too hot to touch, disconnect power immediately.

F4E1 — Heating Element Relay Error (Electric Dryers)

The main control board's relay that powers the heating element has failed, or the heating element itself is faulty. This is one of the most safety-critical dryer codes.

Common causes:

• Welded relay on the control board (stuck in ON position — fire hazard)
• Burned-out heating element (part W10724237)
• Grounded heating element (element touching the housing)
• Blown thermal fuse or high-limit thermostat (part WP3392519)

How to fix:

1. Test the heating element: Measure continuity — should read 8–20 ohms depending on model. Then test for ground fault by measuring between each terminal and the element housing. Any reading means a grounded element that must be replaced immediately.
2. Check the thermal fuse and high-limit thermostat on the heater housing. The thermal fuse should show 0 ohms (continuity). An open reading means it has blown — but always determine WHY it blew before replacing.
3. Test the relay: Listen for a click from the control board when the cycle calls for heat. If the dryer runs extremely hot and does not cycle the heater off, the relay is welded closed — the control board must be replaced immediately.
4. Check the high-limit thermostat — it should be closed at room temperature. An open thermostat with a good fuse usually indicates a heating element problem.

Part cost: Heating element W10724237 costs $30–$70. Thermal fuse WP3392519 costs $5–$15. Main control board W10432257 costs $150–$280.

Warning: A welded relay that keeps the heater on continuously is a fire hazard. If the dryer overheats or the thermal fuse blows repeatedly, do not bypass the fuse — replace the control board.

F4E3 — Gas Valve Relay Error (Gas Dryers Only)

The relay controlling the gas valve solenoid coils has failed, or the gas valve system itself is malfunctioning.

Common causes:

• Gas valve solenoid coils weakened from age (the most common gas dryer no-heat issue)
• Relay failure on the main control board
• Gas supply valve not fully open
• Faulty igniter

How to fix:

1. Verify the gas supply valve behind the dryer is fully open.
2. Observe through the lower access panel while the dryer runs: the igniter should glow bright orange, then gas should ignite within 15 seconds. If the igniter glows repeatedly but the burner doesn't light, the gas valve solenoid coils are weak.
3. Measure coil resistance: booster coil approximately 300 ohms, hold coil approximately 1,000 ohms. Both coils must be functional.
4. Replace the coil kit (279834, $10–$20) — this is the most common gas dryer repair.
5. If the coils test good but the relay doesn't click, the main control board relay has failed. Replace the board (W10432257).

Part cost: Gas valve solenoid coil kit 279834 costs $10–$20. Board W10432257 costs $150–$280.

Warning: If you smell gas that does not ignite within 30 seconds, turn off the gas supply valve and ventilate the room. Do not use any electrical switches.

F6E1 — Communication Error Between Boards

The user interface board and main control board cannot communicate over the serial bus.

Common causes:

• Oxidized connector pins (vibration from unbalanced loads loosens connections)
• Damaged communication ribbon cable or wire harness (part W10888580)
• Failed UI board or main control board
• Corrosion from humidity in laundry room environments

How to fix:

1. Unplug for 5 minutes to reset both boards.
2. Access the wire harness or ribbon cable connecting the UI board (behind the control panel) to the main board. Reseat all connectors firmly.
3. Clean connector pins with electrical contact cleaner spray. Look for green corrosion.
4. If the harness and connectors are clean and seated but the code persists, one of the two boards has failed. The UI board is typically the less expensive replacement to try first.

Part cost: Communication harness W10888580 costs $20–$40. UI board W11170219 costs $75–$180. Main board W10432257 costs $150–$280.

AF — Restricted Airflow

A safety alert indicating the dryer's exhaust system is restricted. This is the most important dryer code from a safety perspective — restricted dryer vents are the leading cause of residential dryer fires (approximately 2,900 fires per year in the US).

Common causes:

• Lint-clogged lint filter (especially if coated with dryer sheet residue)
• Lint accumulation in the exhaust vent duct
• Blocked exterior vent cap (lint, bird nests, debris)
• Vent run too long (over 25-foot equivalent — subtract 5 feet per 90-degree elbow)
• Crushed or kinked flexible vent transition hose behind the dryer

How to fix:

1. Clean the lint filter thoroughly. Wash with soap and water if coated with a waxy film from dryer sheets — this film blocks airflow even when the filter looks clean.
2. Disconnect the exhaust vent hose from the dryer and inspect for lint accumulation.
3. Clean the full vent run from dryer to exterior wall cap using a dryer vent brush kit ($15–$30). This should be done annually at minimum.
4. Check the exterior vent cap — the flap should open freely when the dryer is running. If it doesn't move, the vent is blocked.
5. Verify the vent run is within limits: 25 feet maximum, minus 5 feet for each 90-degree elbow and minus 2.5 feet per 45-degree elbow. Sacramento homes with second-floor laundry often exceed this limit.
6. Replace any flexible foil vent with rigid or semi-rigid metal duct — foil vent collapses and traps lint.

Part cost: No parts typically needed. Dryer vent brush kit costs $15–$30. Professional vent cleaning runs $100–$175.

Warning: If your dryer takes 2+ cycles to dry clothes, the exterior is very hot to touch, or you see lint around the door seal, stop using the dryer and clean the vent system immediately. These are fire warning signs.

L2 — Low Line Voltage (Electric Dryers Only)

The dryer is receiving only 120V instead of the required 240V supply. The drum will turn but the heating element will not operate.

Common causes:

• Half-tripped double-pole breaker (the most common cause — one pole trips while the other stays on)
• Loose wire connections at the outlet, breaker panel, or dryer terminal block
• Damaged power cord
• Corroded outlet contacts

How to fix:

1. Check the circuit breaker panel. Electric dryers use a double-pole 30A breaker. Reset by flipping fully OFF then ON — a half-tripped breaker looks ON but one pole has internally disconnected.
2. Use a multimeter to test the dryer outlet: should read 240V between the two hot (brass) terminals, and 120V between each hot terminal and the neutral/ground.
3. If voltage is correct at the outlet but L2 persists, check the dryer power cord and the terminal block inside the dryer's junction box for loose connections.
4. On 3-prong outlets, verify the neutral wire is connected and intact.

Part cost: Power cord W10841153 (4-prong, 30A) costs $15–$30. Outlet replacement by an electrician runs $100–$200.

Whirlpool Dryer Diagnostic Mode

Standard entry (WED/WGD, Maytag MED/MGD series):

1. Start with the dryer in standby (plugged in, all lights off).
2. Select any three buttons (not Power or Start). Press them in sequence: 1-2-3, 1-2-3, 1-2-3 within 8 seconds.
3. All indicator lights should illuminate. "88" or "888" appears on the display.
4. Press Start to run the automatic test sequence — the dryer tests the motor, heater, moisture sensor, and thermistors in order.
5. Rotate the cycle knob to scroll through individual test modes. Error history is accessible by scrolling to the error log display.

Cabrio/Duet Dryer Diagnostic:

1. Same 1-2-3, 1-2-3, 1-2-3 button sequence within 8 seconds.
2. Press Start to begin automated tests.
3. The last 5 error codes are stored in the control board memory.

Frequently Asked Questions

Q: My Whirlpool dryer runs but produces no heat. What code should I look for? A: Check for L2 first (low voltage on electric dryers) — this is the most commonly missed cause. If no L2 is displayed, run diagnostic mode to check for F4E1 (heating element relay, electric) or F4E3 (gas valve relay, gas). On gas dryers without a code, the gas valve solenoid coils (279834) are the most likely cause — they weaken with age and fail intermittently.

Q: How do I clear the AF (restricted airflow) code? A: AF cannot be cleared by a simple reset — you must address the airflow restriction. Clean the lint filter, the exhaust vent from dryer to exterior wall, and verify the exterior flap opens when the dryer runs. The code will clear on its own once airflow is restored to normal levels.

Q: Why does my dryer keep blowing thermal fuses? A: A thermal fuse that blows repeatedly indicates an underlying problem — never just replace the fuse. The most common causes are: a restricted vent (clean the entire vent system), a grounded heating element (test for ground fault), or a welded relay on the control board (F4E1). Address the root cause to prevent fire risk.

Q: Are Whirlpool dryer error codes the same for gas and electric models? A: Most codes are identical. The key difference is F4E1 (electric heating element relay) vs. F4E3 (gas valve relay). All other codes — F1, F2, F3, F6, AF, and the standalone codes — apply to both gas and electric models.

Q: How often should I clean my dryer vent? A: At minimum once per year. Sacramento homes with long vent runs, multiple elbows, or second-floor laundry should clean every 6 months. If you use dryer sheets, wash the lint filter with soap and water monthly — the waxy residue blocks airflow through the mesh even when lint is removed.

When to Call a Professional

These dryer issues warrant professional repair:

• F1E1 with no visible board damage — Requires component-level diagnosis of MOSFETs and relays.
• F4E1 with a welded relay — A stuck-on heating relay is a fire hazard requiring immediate board replacement.
• Repeated thermal fuse failures — Indicates a root cause that simple fuse replacement won't fix.
• Gas dryer with gas smell — If gas does not ignite within 30 seconds, a professional must diagnose the gas valve and ignition system.
• L2 with correct outlet voltage — May indicate an internal wiring fault inside the dryer requiring electrical diagnosis.
• Any burning smell from the dryer — Stop using immediately and have the heating system inspected.
