Whether you have a gas or an electric Whirlpool dryer, you might experience some issues with it at some point. This is completely normal since every appliance has a certain lifespan. What can be really annoying is when you expect a batch of clothes to be dry but you find out that they’re still wet. You may wonder how this could even happen when you heard the machine spinning. What could be the reason for your Whirlpool dryer not heating? You can find out the most common reasons for this problem below.
Whirlpool Dryer Not Heating and Drying
1. Blown Circuit Breaker
If your machine can run but not heat, there’s a good chance it’s due to a blown circuit breaker. This is great news since you won’t have to replace any parts and get your hands dirty. Power surges can often lead to a breaker blowing.
Reset the Circuit Breaker
Dryer circuits usually feature two circuit breakers. In case your Samsung dryer is spinning but not heating, it means that it’s receiving only 110 volts instead of 220 volts. In this case, all you need to do is simply reset the circuit breaker. You can reset the blown circuit breaker in the main circuit breaker box in your home.
2. Blocked Dryer Vent or Lint Filter
In case you don’t clean the dryer vent often or at all, your dryer will stop working properly at one point. The dust and debris will build up gradually until your Whirlpool dryer stops heating. Thankfully, there is an easy way to solve this problem.
How to Clean a Blocked Vent
You can find the dryer duct in the back of the appliance. Before you get ready to clean the duct, make sure to first unplug the appliance. In case you have a gas dryer, turn off the gas valve. Now disconnect the dryer duct. The best way to clean this part of the appliance is to simply vacuum the inside.
Here’s a short video on how to clean a blocked dryer vent.
3. Burnt Out Heating Element
In case you have an electric dryer, it will feature heating coils and a fan to move hot air into the tumbler and dry your clothes. These coils are located in a metal case and comprise the heating element. Like any other component in your Whirlpool dryer, it can begin to malfunction after some time.
Checking The Heating Element
To test the heating element in an electric Whirlpool dryer, you will first need to remove the back panel and find a metal case that holds the heating coils. That’s the heating element. To check whether it’s working properly, you will need to grab a screwdriver and a multimeter. Before you do anything, make sure that the dryer is disconnected from the power source. After that initial step is done, you can now test the component by following these steps.
Is It Worth Replacing The Heating Element
If you order a Whirlpool heating element replacement, it will cost you $40. But the price will be higher if you hire a repair technician to replace the component. The price will be between $150-250, depending on which technician you hire. If you have an old dryer, it might be best to buy a new one instead of replacing the heating element because other components may start breaking down soon.
4. Inspect for A Blown Thermal Fuse
The thermal fuse serves a vital purpose – it prevents potential fires that can come about when the temperature inside your dryer becomes too high. Essentially, this component is a safety mechanism installed to ensure safety when things go wrong. Because it serves such an important role, it has immense power. The thermal fuse has the power to completely shut off your dryer under certain circumstances. Keep in mind that this is a one-time component that will need to be replaced after it’s been activated.
Locating the Thermal Fuse on Your Dryer
Before you order a replacement for a thermal fuse, you’ll first need to find out its product number. Buying the wrong type of fuse will not do, as it has to be exactly like the one in your dryer. To order a replacement, you’ll first need to locate the fuse in your dryer. On electric models, you’ll find the thermal fuse near the exhaust vent. Gas models feature a thermal fuse located on the blower housing. You might need to remove the front access panel or the rear panel to access the fuse, depending on the exact model of your dryer.
You can find out how to test the thermal fuse for continuity in the video below.
5. Check The Thermostat
The thermostat inside your Whirlpool dryer regulates the temperature inside the appliance and prevents it from overheating. If you have an electric dryer, the thermostat will shut off the voltage to the heating element to prevent the appliance from generating too much heat. In case you have a gas dryer, the thermostat will shut off the voltage to the burner assembly.
How to Check the Thermostat in a Whirlpool Dryer
You can test whether the thermostat in your dryer is causing it not to heat. All you’ll need is a screwdriver and a multimeter.
- The first step is to disconnect the dryer from the power source or shut off the gas valve.
- Use your screwdriver to remove the screws that hold the access panel on the back of your dryer.
- Depending on the model of your dryer, you’ll find the thermostat either on the blower wheel housing or inside the venting system.
- You can easily spot the thermostat that looks like an oval-shaped component and is approximately 1.5 inches in diameter.
- Grab your multimeter and set it to the resistance setting.
- Connect the leads of the multimeter to the thermostat terminals and check them for continuity.
- You should get a reading of 0 ohms if the component is working properly. If it’s not, you’ll get a reading of infinity.
6. No Gas or Faulty Ignition Switch
In case the igniter in your Whirlpool dryer is not working, it means that heat that ignites the gas won’t be generated. As a result, your dryer will not be able to dry clothes. If none of the aforementioned components are causing the appliance to stop heating, the problem is likely in a faulty ignition switch.
Testing a Faulty Ignition Switch
Testing a faulty igniter will require you to grab a multimeter and set it to the lowest resistance setting. To access the igniter, you will need to remove the front panel of your dryer. Remove the belt and the drum and you’ll see a long metallic cylinder. This is the igniter, located on the lower left side of the appliance. Remove it and connect the leads of your multimeter to the terminals of the igniter. If you get a reading of between 50-400 ohms, it means that the igniter is working properly.

SOLVED: Whirlpool Dryer Not Heating
By now, you’ve probably figured out that you have some inspecting to do if you want to find out what’s actually the problem behind your Whirlpool dryer not heating. Start with the simple steps, like inspecting the dryer vent. In case there isn’t much debris there, you can start looking at the other components one by one. Keep in mind that multiple components can fail at the same time, so you might need to replace more than one part for your dryer to start working normally again.
