Dryer Not Heating? Here’s How to Solve It

Have you ever experienced the frustration of a dryer not heating? Imagine pulling out your favorite shirt only to find it cold and damp. It’s a common problem that Nick’s Appliance Repair Service is adept at handling. With our guide, you’ll learn how to understand your dryer heating issue and troubleshoot the issue yourself.

Understanding Your Dryer

A dryer is a complex appliance that combines heat and motion to dry clothes. Whether you have a gas or electric dryer, the fundamental principles remain the same. Both types have a dryer drum where the clothes are placed, a heating element that produces heat, and a motor that turns the drum. There’s also a thermostat to regulate the dryer temperature and a thermal fuse, a safety device designed to prevent fires if the dryer temperature exceeds safe limits.

Common Reasons Why Your Dryer May Not Be Heating

Understanding why a dryer is not heating requires identifying the potential culprits. Here are some of the most common reasons:

Tripped Circuit Breaker

A dryer not heating could be as simple as a tripped circuit breaker in your electrical panel. If one of the two circuit breakers dedicated to the drum rollers dryer trips, the drum can spin without producing heat.

Faulty Heating Element

The heating element is responsible for producing the hot air that dries your clothes. If the heating element fails, your dryer won’t heat. This problem is more common in electric dryers than gas dryers.

Broken Thermostat

Your dryer’s thermostat leads the heating element, regulating the temperature within the drum. If the dryer belt or thermostat is broken, it might not signal the heating element to generate heat.

Blown Thermal Fuse

A blown thermal fuse is another common issue. This safety device is designed to shut off the dryer’s heating element if the temperature exceeds a certain point. If the thermal fuse is blown, the dryer might run but not heat up.

Blocked Venting

A blocked ventilation hose or lint screen reduces airflow, causing the dryer to work harder to dry your clothes. This strain can cause overheating and blow the thermal fuse, resulting in the dryer not heating.

Igniter Issues (For Gas Dryers)

Gas dryers have an additional component, the igniter, which lights the gas and creates heat. If the igniter fails, the gas dryer valve won’t open, and the dryer won’t heat.

How to Identify the Problem

Identifying the problem begins with ruling out simple solutions. Check your circuit breakers and reset them if needed. Also, ensure the gas supply (for gas dryers) is turned on and your dryer is set to heat and not cool setting.

You’ll need to delve into the components that fail the dryer itself for more complex issues. A multimeter test can help identify problems with the heating element, thermostat, and thermal fuse. Remember to disconnect the dryer from the power source before starting any inspection.

Troubleshooting and Fixes for Common Problems

Tripped Circuit Breaker:

Reset the circuit breaker in your electrical panel. If it continues to trip, you might have a faulty circuit breaker or a problem with your dryer’s electrical components.

Faulty Heating Element:

It may be broken if the heating element leads are not generating heat. Testing with a multimeter can confirm this. You’ll need to replace a broken heating element.

Broken Thermostat:

A faulty thermostat can be identified with a multimeter test. If it’s not functioning correctly, most models must be replaced.

Blown Thermal Fuse:

If the dryer temperature exceeds the limit, the thermal fuse will blow. Use a multimeter to check for continuity. If the thermal fuse is blown, it must be replaced.

Blocked Venting:

Regularly clean your lint screen and dryer vent with a vacuum attachment or a ventilation cleaning kit to prevent further blockages. If you find lint blockages or ventilation blockages, clear them out.

Igniter Issues (For Gas Dryers):

If the igniter isn’t hot, water isn’t glowing, or if it glows but doesn’t ignite the gas, it isn’t accurate. Replacement is the only solution.

Preventive Measures to Avoid Future Heating Issues

Avoid future dryer heating issues by taking the following preventive measures:

Clean the Lint Screen Regularly:

A clogged lint screen or trap can cause the dryer to overheat, blowing the thermal fuse. Clean the lint trap or screen after each use.

Inspect and Clean the Dryer Vent:

Over time, lint buildup in the dryer vent can reduce airflow and lead to overheating. Regularly inspect and clean the duct using a ventilation cleaning kit.

Regular Maintenance:

Regular dryer maintenance, including checking the heating coils, thermostats, and thermal fuses, can help avoid sudden breakdowns.

Proper Loading:

Overloading warm water into the dryer drum can cause the motor to overwork, potentially leading to overheating. Ensure you’re not stuffing the dryer drum with too many wet clothes.

Avoid Kinks in the Ventilation Hose:

Ensure the ventilation hose is correctly installed without any kinks or bends. This will ensure a steady flow of hot air.


A dryer not heating can be frustrating and inconvenient, but with a bit of understanding of how dryers work and some troubleshooting skills, you can resolve most issues yourself. Regular maintenance and cleaning can prevent future heating problems and extend the life of your appliance. If you need clarification on any repairs, it’s always best to consult a professional like Nick’s Appliance Repair Service to ensure your dryer is functioning safely, correctly, and efficiently.


Why is my dryer running but not heating?

If your dryer is running but not heating, it could be due to a few reasons. It’s possible your heating elements, like in a Whirlpool or Samsung dryer, are faulty, or the thermal fuse is blown. Dryer problems often result in the machine running but not producing heat.

How do you fix a dryer that won’t heat up?

Fixing a dryer that won’t heat up involves identifying the problem first. Check for common issues such as a faulty timer or heating element, a broken thermostat, or blown thermal fuses. If these components are in order, it might be an issue with the gas pipe (for gas dryers) or a problem with the timer motor. Once you’ve identified the case, you may need to replace the faulty part. Remember to disconnect the dryer from the power source before starting repair work.

How do I know if my thermal fuse is blown?

A common sign that your thermal fuse is blown is if your dryer starts a spin cycle but doesn’t produce heat. Another clue is if the dryer door opens and the drum stops spinning abruptly – this could indicate a safety issue like a blown a fuse. A multimeter test can confirm if the fuse is blown, as it will show a lack of continuity.

Why is my dryer blowing cold air?

If your dryer is blowing cold air, it might be due to a heating problem, such as a broken heating element or a blown thermal fuse. It could also be because the dryer belt is worn out and needs to be replaced. If your dryer is older and has been causing a spike in your gas bill, it might be more cost-effective to consider replacing it entirely.

What role does the gas valve play in my dryer’s heating issue?

The gas valve controls the flow of gas into the burner assembly in gas dryers. If the valve is faulty, it can prevent the dryer from heating. It’s essential to check the gas valve if you’re experiencing heating problems with your gas dryer.
