Whirlpool Dryer Not Heating? Complete Repair Guide

Common Symptoms

• Dryer runs but clothes stay damp or wet
• Cycles take much longer than usual
• Error code AF appears on display
• No heat at all inside the drum
• Dryer stops mid-cycle with error code

What Causes This Problem?

• Clogged lint filter or vent – Most common cause of poor heating
• Faulty heating element – Burned out element needs replacement
• Failed thermal fuse – Safety device that blows when dryer overheats
• Defective cycling thermostat – Regulates temperature
• Bad igniter (gas dryers) – Won’t ignite gas for heat

DIY Troubleshooting Steps

1. Clean lint filter – Clean before every load
2. Check vent hose – Disconnect and remove lint buildup
3. Inspect outside vent – Ensure flap opens freely
4. Reset dryer – Unplug for 5-10 minutes
5. Check for error codes – AF indicates airflow restriction

When to Call a Professional

• Cleaning vent doesn’t restore heat
• You smell burning or notice unusual noises
• Thermal fuse needs replacement
• You’re not comfortable disassembling dryer
