Dryer Not Heating? How to Troubleshoot and Fix the Issue

Is your clothes dryer failing to generate enough heat? It can be frustrating when your dryer stops heating up properly, but before you rush to call a technician, there are some simple repairs you can try yourself.

In this comprehensive guide, we will explore the most common causes of a dryer not heating and provide step-by-step instructions on how to troubleshoot and fix the issue.

By following these tips, you may be able to save time and money by resolving the problem on your own.

Common Causes of a Dryer Not Heating

There are several potential reasons why your dryer may not be producing enough heat.

By understanding these common causes, you can narrow down the issue and take the necessary steps to fix it.

Here are seven common culprits:

  1. Incorrect Voltage Delivered to the Dryer: Ensure that the dryer is properly plugged in and that all circuit breakers are in their set positions. Incorrect voltage supply can prevent the dryer from generating heat.
  2. Blown Fuse or Tripped Circuit Breaker: The fuse and circuit breaker act as safety features for dryers. If there is an issue with the internal parts of the dryer, the fuse is designed to blow first to protect other components. Check the fuse and replace it if necessary.
  3. Debris Blockage in the Heating Element: If debris from clothing accumulates and blocks the heating element, the machine may overheat and shut down. Clean the lint screen and vent hose to remove any obstructions.
  4. Tripped Circuit Breaker: Electric dryers typically have two breakers—one for the drum motor and one for the heating element. If the circuit breaker trips, reset it and check if the dryer starts heating again.
  5. No Gas Flow: If your dryer is gas-powered, check if there is still gas flowing to the machine. Ensure that your gas bill is up to date and contact your gas company if necessary.
  6. Uneven Loading of Clothes: Mixing small and large items in the dryer can lead to heating problems, especially in auto-dry cycle machines. Loading sheets and towels together, for example, can cause the dryer to heat at lower levels, resulting in incomplete drying.
  7. Motor Overheating: A malfunctioning washer or spinner that leaves clothes excessively wet can overwork the dryer’s motor, leading to overheating. The electric fuse will blow before the motor reaches dangerous temperatures.

Troubleshooting and Repair Steps

To fix a dryer that is not heating, you can follow these eight repair steps.

Before you begin, make sure to unplug the dryer from the power source and take necessary safety precautions.

Step 1: Prep Work

Start by disconnecting the dryer from the wall or turning off the dryer circuit breaker. This ensures that there is no power supply to the machine.

Remove the front or back cover of the dryer, depending on the model, to access the internal components.

Step 2: Check the Thermal Fuse

The thermal fuse is a common cause of a dryer not heating. Using a multimeter set to the continuity or resistance mode, check the thermal fuse for continuity.

If there is no continuity, the fuse is blown and needs to be replaced.

Step 3: Check the Thermal Cut Off

Similar to the thermal fuse, the thermal cut off is another component that can cause the dryer to stop heating.

Test its continuity with a multimeter and replace it if necessary.

Step 4: Check the High Limit Thermostat

The high limit thermostat is responsible for regulating the temperature inside the dryer.

Test its continuity using a multimeter and replace it if there is no continuity.

Step 5: Check the Cycling Thermostat

The cycling thermostat helps maintain the target temperature by cycling the heat source on and off.

Test its continuity with a multimeter and replace it if needed.

Step 6: Check the Heating Element

The heating element is the part of the dryer that generates the necessary heat for drying clothes.

Test its continuity with a multimeter and replace it if there is no continuity.

Step 7: Check Other Parts of the Machine

If the dryer still doesn’t heat up after checking the above components, you may need to examine other parts such as the timer assembly, main control board, or any faulty wiring.

Seek professional help if needed.

Step 8: Replace with the Correct Parts

When replacing any faulty parts, ensure that you use the correct replacements.

Ideally, try to get parts from the original equipment manufacturer (OEM) or find alternatives with the same specifications or model number.

By following these troubleshooting and repair steps, you can potentially resolve the issue of a dryer not heating and restore its functionality.

Consider a New Dryer
