Dryer Not Heating

Quick answer

First, check if the dryer is receiving power and the circuit breaker isn't tripped. Ensure the dryer vent is clear. If these are fine, you may need to replace the heating element or thermal fuse.

Confirm the symptom

• Dryer tumbles but doesn't produce heat.
• Clothes remain wet after a full cycle.
• Dryer makes noise but doesn't heat up.
• Dryer displays error codes related to heating.
• Dryer is less than 8 years old and has been well-maintained.

Tools and prep

• Screwdriver (Phillips and/or flathead)
• Multimeter
• New heating element or thermal fuse (if needed)
• Work gloves
• Safety glasses
• Unplug the dryer or turn off the power at the circuit breaker.
• Ensure the dryer is empty and cool to the touch.

Step-by-step troubleshooting

1. Check Power Supply
   Do: Ensure the dryer is plugged in and the power cord is not damaged.
   Observe: Check if the dryer is receiving power.
   Means: The dryer should power on and the drum should turn.
   Next: Check the circuit breaker.
2. Check Circuit Breaker
   Do: Locate your home's circuit breaker panel.
   Observe: Look for any tripped breakers.
   Means: If tripped, reset the breaker.
   Next: Check the dryer vent.
3. Check Dryer Vent
   Do: Disconnect the vent from the dryer and check for blockages.
   Observe: Ensure the vent is clear and air can flow freely.
   Means: A clear vent allows proper airflow.
   Next: Check the heating element.
4. Check Heating Element
   Do: Access the heating element and use a multimeter to test for continuity.
   Observe: A functional heating element will show continuity.
   Means: No continuity indicates a faulty heating element.
   Next: Replace the heating element if necessary.
5. Check Thermal Fuse
   Do: Locate the thermal fuse and test it with a multimeter.
   Observe: A good thermal fuse will show continuity.
   Means: No continuity means the thermal fuse is blown.
   Next: Replace the thermal fuse if necessary.
6. Check Thermostat
   Do: Test the cycling thermostat and high-limit thermostat with a multimeter.
   Observe: Both should show continuity when cool.
   Means: No continuity indicates a faulty thermostat.
   Next: Replace the thermostat if necessary.
7. Check Control Board
   Do: Inspect the control board for any visible damage.
   Observe: Look for burnt areas or damaged components.
   Means: Visible damage indicates a faulty control board.
   Next: Replace the control board if necessary.

Common causes

Parts matching

Ensure you have the correct parts before starting repairs. Match the part numbers with your dryer's model.

• Heating Element
• Thermal Fuse
• Cycling Thermostat
• High-Limit Thermostat
• Control Board
• Power Cord

Always check the part number against your dryer's model to ensure compatibility.

When to call a professional

• If you're not comfortable working with electrical components.
• If the dryer is under warranty.
• If the issue persists after checking all components.
• If you encounter any gas-related issues (for gas dryers).
• If you suspect internal wiring problems.
• If the dryer shows error codes you don't understand.
