Whirlpool Dryer Not Heating

A Whirlpool dryer that doesn’t produce enough heat-or worse, doesn’t heat up at all-can be frustrating and inconvenient. Whether you own an electric or gas model, insufficient heating can result from various issues, including a blown thermal fuse, faulty heating element, or restricted airflow.
Common Causes of a Whirlpool Dryer Not Heating
Several factors can cause a Whirlpool dryer to stop heating or produce insufficient heat:
1. Blown Thermal Fuse: The thermal fuse is a safety component that shuts off power to the heating element if the dryer overheats. If it blows, the dryer will run but won’t heat up.
2. Faulty Heating Element (Electric Models): The heating element generates the heat necessary for drying clothes. If it burns out, the dryer will not heat.
3. Defective Gas Igniter or Gas Valve Coils (Gas Models): Gas dryers rely on an igniter and solenoid coils to ignite the gas. If these parts fail, the dryer won’t produce heat.
4. Malfunctioning Thermostats: A cycling thermostat or high-limit thermostat regulates heat inside the dryer. If they fail, the dryer may not heat correctly.
5. Clogged Dryer Vent or Lint Filter: Restricted airflow due to lint buildup in the vent or lint filter can reduce heating efficiency and extend drying times.
6. Broken Timer or Control Board: The control board or timer directs power to the heating element or gas burner. If these components fail, the dryer may not heat at all.
How to Fix a Whirlpool Dryer That Won’t Heat Up
1. Check the Power Supply (Electric Dryers)
Before inspecting internal components, ensure your dryer is receiving proper power.
Steps to Check Power Supply:
- Inspect the Power Cord - Whirlpool electric dryers require a 240V power supply. A loose or damaged cord can cause heating issues.
- Test the Circuit Breaker - Check your home’s breaker panel. If the breaker for the dryer has tripped, reset it.
- Measure Voltage at the Outlet - Use a multimeter to check for 240V output. If voltage is incorrect, contact an electrician.
Fix: If the dryer isn't getting 240V power, reset the breaker or call an electrician.
2. Test and Replace the Thermal Fuse
A blown thermal fuse is a common cause of a Whirlpool dryer not heating.
Steps to Replace the Thermal Fuse:
- Unplug the Dryer - Always disconnect power before repairs.
- Locate the Thermal Fuse - Found on the blower housing or exhaust duct.
- Test for Continuity - Use a multimeter to check for continuity. If there’s none, the fuse is blown.
- Replace the Fuse - Remove screws, disconnect wires, and install a new fuse.
Fix: Replace the blown thermal fuse and clean the vent to prevent overheating.
3. Inspect and Replace the Heating Element (Electric Dryers)
A faulty heating element can cause the dryer to stop producing heat.
Steps to Replace the Heating Element:
- Disconnect Power - Safety first! Unplug the dryer.
- Access the Heating Element - Remove the back panel to find the heating element housing.
- Test for Continuity - Use a multimeter to check for continuity across the heating element terminals.
- Install a New Element - If no continuity, remove the mounting screws, disconnect wires, and replace the heating element.
Fix: Install a compatible heating element for your Whirlpool dryer model.
4. Check the Gas Igniter and Gas Valve Coils (Gas Dryers)
If your gas dryer is not heating, the issue could be with the igniter or gas valve solenoids.
Steps to Replace a Faulty Igniter:
- Turn Off Gas and Power - Shut off the gas supply and unplug the dryer.
- Locate the Igniter - Found near the gas burner assembly.
- Test with a Multimeter - If there’s no continuity, replace the igniter.
- Install a New Igniter - Remove mounting screws, disconnect wires, and secure the new igniter in place.
Fix: If the igniter doesn’t glow or has no continuity, replace it.
Steps to Replace gas Valve Coils:
- Access the Gas Valve Assembly - Remove the front panel.
- Test the Coils - If the igniter glows but the burner doesn’t ignite, the coils are likely faulty.
- Replace the Coils - Disconnect wires, remove the old coils, and install new ones.
Fix: If the igniter glows but no flame appears , replace the solenoid coils .
5. Clean the Dryer Vent and Lint Filter
A clogged vent reduces airflow, making the dryer less efficient.
Steps to Clean the Dryer Vent:
- Unplug the Dryer - Disconnect power.
- Remove the Vent Hose - Check for lint buildup.
- Use a Vacuum or Vent Brush - Clean out the lint from the hose and exhaust vent.
- Reattach and Test - Secure the vent and run a test cycle.
Fix: Clean the vent every 6-12 months to prevent overheating issues.
How to Prevent a Whirlpool Dryer from Not Heating in the Future
To avoid future heating problems, follow these maintenance tips:
- Clean the Lint Filter After Every Load - Prevents airflow restrictions.
- Inspect and Clean the Dryer Vent Every 6-12 Months - Reduces the risk of overheating.
- Avoid Overloading the Dryer - Ensures even heating and prevents strain on components.
- Check the Power and Gas Supply Regularly - Ensures proper voltage or gas flow.
- Test the Heating Element and Igniter Annually - Helps detect wear and tear early.
- Replace the Thermal Fuse if It Blows - A blown fuse often indicates a clogged vent.
