Common Causes of Whirlpool Dryer Heating Problems

Troubleshooting why your Whirlpool dryer is not heating starts with understanding common issues. Here is a closer look at them.

Blocked Lint Screen

A clogged lint screen can block airflow. This often leads to overheating and shutdown. Clean it after every load to prevent problems.

Exhaust Vent Blockage

A blocked exhaust vent restricts airflow. This can cause your dryer to run cool. Check for lint build-up or external obstructions and remove them.

Faulty Heating Element

The heating element might burn out or get damaged. If your dryer blows cool air, this could be why. You’ll likely need to replace the element.

Malfunctioning Thermostat

A bad thermostat can misread temperatures. This makes your dryer heat incorrectly. Test the thermostat and replace it if faulty.

Broken Thermal Fuse

Safety features like the thermal fuse can blow if the dryer overheats. If it fails, your dryer won’t heat at all. You must replace the blown fuse.

Defective Timer or Cycling Thermostat

When timers or cycling thermostats don’t work, they disrupt normal heating cycles. Inspect these parts and consider replacing them if they are defective.

Step-by-Step Guide to Diagnosing Your Dryer

Troubleshoot the root cause of why your Whirlpool dryer is not heating with this practical guide.

Checking the Lint Screen and Exhaust Vent

Begin by examining the lint screen. Remove any accumulated lint. This is a common culprit for airflow blockages. Next, check the exhaust vent. Ensure it’s clear from lint build-up and external obstructions. A clear path for air is crucial for proper heating.

Testing the Heating Element

If cleaning doesn’t solve the issue, test the heating element. This component generates the heat, and if it’s faulty, it needs replacement. Use a multimeter to check for continuity. No continuity means a new heating element is in order.

Inspecting the Thermostat

Move on to the thermostat. It should accurately gauge and regulate the temperature. A malfunctioning thermostat requires a continuity test. Replace it if the test shows it’s defective.

Assessing the Thermal Fuse

The thermal fuse is a safety device designed to blow if the dryer gets too hot. If your dryer isn’t heating, this fuse could be the reason. Test with a multimeter. A blown fuse can’t be repaired; it must be replaced.

Evaluating the Timer and Cycling Thermostat

Lastly, evaluate the timer and cycling thermostat. These are responsible for the heating cycles. If they’re not working properly, your dryer might not heat as it should. Inspect these parts for wear and test them for functionality. Replace if found to be defective.
