Whirlpool Dryer Keeps Blowing Thermal Fuse (With Fixes)

If your Whirlpool dryer keeps blowing the thermal fuse, it could be a sign that something is wrong with your appliance.

The thermal fuse is designed to protect the dryer from overheating, and if it repeatedly trips or blows, it could mean there’s an issue with the dryer motor, heating element, exhaust vent, or other components. 

If you experience this issue, a few simple fixes can help get your dryer running again. Some likely causes and solutions are discussed below. 

In this article, we explain some main reasons for this problem and share with you the correct solution to this problem

Whirlpool Dryer Keeps Blowing Thermal Fuse

1. Air Flow Issue

Airflow issues can be the cause of a Whirlpool dryer blowing its thermal fuse. This issue occurs when the dryer is unable to get enough air to cool the components inside it.

The most common issue is a blocked or clogged vent system. To check if this is the problem, turn off the dryer and disconnect the duct from the back of it. 

Then inspect the vent for any blockages or debris that might be blocking airflow. If there are no blockages, then inspect the duct for kinks or bends that might be preventing airflow. 

2. Worn-Out Heating Element 

A worn-out heating element can cause the dryer to keep blowing a thermal fuse. 

The heating element is responsible for providing heat to the dryer, and if it isn’t working properly or becomes too hot, then it can cause the dryer to overheat and blow a thermal fuse. 

In this case, you will need to replace the heating element for your Whirlpool Dryer in order to fix this issue. It is important that you follow instructions during the installation of a new piece as wrong connections could lead to further damage to your appliance. 

To ensure proper installation, contact a trained professional or take advantage of Whirlpool’s customer support service team if needed. This should fix the problem with your Whirlpool Dryer!

3. Faulty Cycling Thermostat

A faulty cycling thermostat is a common cause for a Whirlpool dryer to keep blowing its thermal fuse. 

When the thermostat senses that the dryer is not reaching the desired temperature, it shuts off power to the heating element until the temperature drops and then turns back on. 

Over time, if this thermostat becomes faulty, it will fail to sense when the dryer has reached the desired temperature and will turn the heating element back on before it reaches its target temperature. 

This can cause the thermal fuse to blow due to overheating. To check if this is causing your issue, you should locate and test the cycling thermostat. If it is found to be faulty, it should be replaced.

4. Accumulation Of Lint In The Dryer’s Exhaust Vent

Lint accumulation in the exhaust vent of a dryer can be a major cause of overheating and malfunctioning of the dryer. It is important to clear out lint on a regular basis, as it can easily build up and become a fire hazard. 

To clean out lint in your dryer’s exhaust vent, you need to first disconnect the exhaust vent from the back of the dryer. Vacuum out the lint, and then use a brush to scrub the interior of the vent. 

Once you reconnect the exhaust vent, make sure it is securely fastened for safety. Regular maintenance and cleaning will help to keep your dryer running efficiently and safely.

5. Damaged Blower Wheel

A blower wheel is the main component of an HVAC system that moves air through the ducts and into the living space. 

Over time, it can become damaged due to dirt and dust accumulation or simply wear and tear, which can affect its performance and efficiency. 

Replacing a damaged blower wheel with a new one should be done as soon as possible to ensure proper air movement and help reduce energy costs. 

It’s important to note, however, that replacing a blower wheel requires the expertise of a qualified HVAC technician and may require special tools.

 If you find that your blower wheel is damaged, it’s best to call an experienced professional for assistance.

6. Contact Customer Service

If your Whirlpool dryer is continually blowing the thermal fuse, it may be a sign of a more serious problem. You should contact customer service as soon as possible to arrange for an inspection and repair. 

Customer service representatives can help you assess the cause of the issue and provide professional advice on how to fix it.


It is essential to take the necessary steps to prevent your Whirlpool dryer from blowing its thermal fuse. 

Regularly inspecting and cleaning the lint trap, venting system, and exhaust ducts can help reduce potential problems that may cause a blown thermal fuse in the future. 

If you are still having issues with your Whirlpool dryer after following these measures, it’s best to contact a professional appliance repair service for further assistance. 

With proper maintenance and care of your Whirlpool Dryer, you will be able to keep it running smoothly without any more blown fuses!


How do you bypass the thermal fuse on a Whirlpool dryer?

It is important to note, however, that bypassing the thermal fuse is not recommended as it could put you and your home at risk of a fire hazard. 

Instead, if your Whirlpool dryer is continually blowing the thermal fuse, it is important to identify and fix the underlying issue that is causing the problem before replacing the fuse.

Will the Whirlpool dryer run with a blown thermal fuse?

No, the Whirlpool dryer will not run with a blown thermal fuse. The thermal fuse acts as a safety device that shuts off power to the dryer if it overheats, so it is essential for the safe and proper operation of the appliance. 

A blown thermal fuse must be replaced in order to get your dryer running again. It is important to check and verify any other potential problems before replacing the fuse, such as clogged ventilation systems or faulty elements. 

Why does my tumble dryer keep blowing fuses?

If your tumble dryer keeps blowing fuses, the first thing you should check is if the heating element has been damaged. A damaged or failing heating element can cause excessive current draw and blow the thermal fuse. 

Other possible causes could be a faulty thermostat that isn’t shutting off power to the heating element, air vent blockage causing an overheating issue, or a timer motor problem not switching off power to the heater at the end of each cycle. 

How do I know if my dryer thermostat is bad?

If your dryer is not heating up properly or turning off too quickly during a cycle, it could be a sign that the thermostat is faulty. 

Other symptoms can include sporadic heat or no heat, a burning smell, and unusual noises coming from the machine. To determine if the thermostat is bad, you can test it with an ohmmeter to measure electrical resistance. 

If the reading is much higher than what’s listed in your user manual, then you likely need to replace it as soon as possible.
