Quick answer
If your Whirlpool dryer isn't heating, first check the thermal fuse and heating element. Replace any damaged parts after turning off the power. Ensure the dryer is properly grounded.
Confirm the symptom
- Dryer runs but clothes remain damp
- No heat coming from the vent
- Dryer makes noise but doesn't dry effectively
Tools and prep
- Screwdrivers (flathead and Phillips)
- Multimeter for testing electrical components
- Work gloves for safety
- Owner’s manual for model-specific details
- Ventilation in a well-ventilated area
Step-by-step troubleshooting
- Turn Off PowerDo: Unplug the dryer or turn off the circuit breaker.Observe: Dryer stops running.Means: Power is safely disconnected.Next: Check thermal fuse
- Check Thermal FuseDo: Locate and test the thermal fuse with a multimeter.Observe: Multimeter shows no continuity.Means: Thermal fuse is blown.Next: Replace thermal fuse
- Inspect Heating ElementDo: Remove the back panel and visually check the heating element for cracks or breaks.Observe: Heating element is damaged or broken.Means: Heating element needs replacement.Next: Replace heating element
- Test ThermostatDo: Use a multimeter to test the thermostat for continuity.Observe: No continuity in the thermostat.Means: Thermostat is faulty.Next: Replace thermostat
- Check Power SupplyDo: Verify the dryer is receiving the correct voltage.Observe: Voltage is significantly lower than required.Means: Electrical issue with the power supply.Next: Consult an electrician
- Clean Vent and Lint FilterDo: Remove lint from the vent and lint filter thoroughly.Observe: Significant lint buildup is removed.Means: Improved airflow may resolve overheating issues.Next: Test dryer operation
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Blown Thermal Fuse Overheating or blocked vent caused the fuse to blow. | Common | Easy | Thermal Fuse |
| Faulty Heating Element Cracks or breaks prevent heat generation. | Common | Easy–Medium | Heating Element |
| Failed Thermostat Thermostat stops allowing current to the heating element. | Sometimes | Medium | Thermostat |
| Incorrect Voltage Supply Dryer requires 240V; lower voltage prevents heating. | Rare | Hard | Electrical Service |
| Blocked Vent or Lint Filter Restricted airflow causes overheating and safety shutdown. | Sometimes | Easy | Vent Cleaning Kit |
| Defective Timer or Control Board Malfunctioning control board fails to activate heating. | Rare | Hard | Control Board |

FAQ
Why is my Whirlpool dryer running but not heating?
Common causes include a blown thermal fuse, faulty heating element, or failed thermostat. Check these parts first.
Can a clogged vent cause the dryer not to heat?
Yes, a clogged vent restricts airflow, causing the dryer to overheat and shut off the heating element for safety.
How do I test the thermal fuse?
Use a multimeter to check for continuity. If there’s no continuity, the fuse is blown and needs replacement.
What voltage does my Whirlpool dryer need?
Most electric Whirlpool dryers require 240 volts. Check the model label for confirmation.
