A dryer that doesn’t dry clothes leaves you with a pile of wet laundry and even more questions. Wondering why is my dryer running but not heating? Overloading can restrict airflow, preventing heat from reaching every item. Troubleshoot a Whirlpool dryer not heating by investigating the most likely reasons to solve the problem.
Common Causes for a Whirlpool Dryer Not Heating
A Whirlpool dryer not heating can usually be fixed with a minor adjustment, DIY fix, or professional repair. How do you know the right solution? The following common causes can guide your troubleshooting to the right answer.
Am I Using the Right Whirlpool Dryer Setting?
Most Whirlpool dryers have a variety of Automatic Cycles that adjust heat and drying time for specific loads. When on an Automatic Cycle, the dryer senses the moisture level and dryness of the air. Once the right level of moisture or dryness is sensed, the dryer stops.
By contrast, the Timed Dry setting dries clothes for a set period of time, regardless of moisture level. Using the Timed Dry setting can leave certain loads damp, making it seem like the dryer won’t heat. For optimum performance, use an Automatic Cycle for most dryer loads. Reserve the Timed Dry function for a few damp items that benefit from a short amount of drying time.
Is the Dryer Overloaded?
Overloading is one of the most common reasons for a Whirlpool dryer not heating. Piling too many clothes in the dryer drum limits the circulation of hot air. When airflow is restricted, the dryer takes forever to dry clothing or requires more than one cycle to get the job done.
To prevent overloading, only fill the dryer with one wash load at a time. Make sure the dryer is no more than ¾ of the way full to allow for maximum airflow.
Are the Dryer Vents Clogged?
Air circulation can also be restricted if the dryer vents are clogged. A buildup of lint and debris can cause blockages in the vent that limit airflow, elongating drying times. These blockages are more likely if the lint screen is also clogged. A clogged screen won’t be able to catch lint or other objects, causing more buildup in dryer vents.
If you think your dryer isn’t providing adequate heat, the vents may need cleaning to restore proper airflow. We recommend scheduling professional dryer vent cleaning at least once a year to remove any buildup that can cause clogs. Cleaning the lint trap after each drying cycle can also improve air circulation and lessen the chance of blockages.
Has the Thermal Fuse Blown?
The thermal fuse is a protective feature that blows if the dryer is in danger of overheating. When it blows, the dryer will stop running and function won’t be restored until the fuse is replaced. While a fuse can blow if it’s faulty, overheating is the more likely cause. Since clogged dryer vents are a common cause of overheating, we recommend checking the vents for blockages if the thermal fuse blows.
Have the Whirlpool Gas Valve Solenoids Failed?
In gas dryers, the gas valve solenoids open the gas valve that allows gas to flow. If the solenoids fail and can’t open the valve, gas won’t be present for the igniter to light and provide heat.
How can you tell if the gas valve solenoids are responsible for a Whirlpool dryer not heating? Watch the igniter as it tries to light. If it glows but goes out without igniting the gas, the solenoids have likely failed. Even if only one solenoid has failed, it’s recommended that all of them are professionally replaced.
Is My Whirlpool Dryer Heating Element Defective?
For electric dryers, a Whirlpool dryer heating element creates heat when its wires receive an electric current. Over time, the heating element can burn out and will no longer receive current or produce heat. If the heating element shows no continuity with multimeter testing, it’s likely burned out and requires professional replacement.
