Why Your Dryer Isn’t Heating — 7 Most Common Causes
There is nothing more annoying than realising you just wasted an entire day and your laundry is still damp. You toss the clothes back in, hit the start button again, wait another hour…and still, nothing. Your dryer not working can mess up your whole routine. Put your chin up because most heating issues come from a few common problems. Many of them are easy to understand once they are explained. So, that is what we are going to do. We will walk you through the top reasons your dryer is not heating up. At S&S APPLIANCES, we help homeowners fix these problems every day, so you are in good hands.
How Your Dryer Tells You Something’s Up
A dryer not heating can only mean something inside the appliance is not working the way it should. Dryers need heat, airflow, and power to dry clothes. All of these components need to work, or the entire machine struggles.
Let’s see when you should start worrying about your dryer:
- Clothes staying damp
- Dryer running longer than normal
- Air inside the drum feels cool
- Burning smells or overheating
Reasons Your Dryer Won’t Heat Up:
It would be helpful if you knew what was causing the issues. You can, then, decide whether it is a quick fix or something you need a professional to repair. Come with us to find some of the common causes of a dryer malfunction:
1. A Blown Thermal Fuse
The thermal fuse is a small safety device that “blows” when the dryer overheats. The dryer stops heating completely once it goes out. This usually happens because of lint buildup. Lint can easily restrict airflow.
Why it matters:
The dryer can get too hot if the airflow is blocked. The good part is that the fuse protects the machine from fire. The bad part is that it also stops heating until replaced.
2. Faulty Heating Element
The heating element is what warms the air inside the dryer. It can burn out if it is old, just like a light bulb.
How you will notice:
- Your dryer tumbles normally, but the air inside stays cold.
- A technician can test the element and replace it if needed.
3. Clogged Lint Screen or Vent
Surprisingly, one of the biggest reasons a dryer is not heating is simply a clogged vent. Here is what happens: Lint blocks airflow → the heat can’t circulate → clothes take forever to dry.
Signs to watch for:
- The dryer feels hot on the outside
- Clothes are warm but still damp
- Burning smell
Tip from S&S APPLIANCES:
You should clean your lint trap after every laundry time. Also, schedule vent cleaning at least once a year.
4. Broken Igniter (Gas Dryers Only)
Gas dryers have a component called an igniter. It is what lights the burner that produces heat. Igniter failing means no flame means no heat. What happens is that the dryer runs but never warms up.
5. Tripped Circuit Breaker
Electric dryers need 240 volts to heat properly. Keep an eye on the breaker tripping. The dryer would still work normally, but without heat.
Check your panel
You might see one switch flipped halfway. Reset it. Then, try running the dryer again.
6. Faulty Thermostat
Dryers contain several thermostats that monitor temperature. All of them should work. If one fails, the machine will shut off the heat to avoid overheating.
Symptoms include:
- The dryer stops heating randomly
- Long drying times
- The dryer is getting too hot
Should I DIY this or call someone?
Thermostats require proper diagnosis. Calling a professional helps.
7. Damaged Timer or Control Board
The control board or timer tells your dryer when to heat. Your dryer runs like usual when these components start malfunctioning. The issue is that it never signals the heating system to turn on. It is also tricky because the issue is electrical and harder to identify without tools.
How to Prevent Heating Problems
Keeping your dryer healthy is easier than you think. Come with us to learn some simple steps that keep your dryer running smoothly:
- Clean your lint trap after every cycle
- Avoid overloading the drum
- Have the dryer vent professionally cleaned yearly
- Listen for unusual noises
- Call a technician if something feels “off”

“Your dryer is not heating” Sure, it is frustrating, but not a mysterious problem. In most cases, the issue comes from a clogged vent because of lint, a blown fuse, or a faulty heating part.

FAQs
Why is my dryer on but not heating?
The most common reasons are a tripped thermal fuse and a clogged vent. Some other reasons can be a broken heating element or a malfunctioning gas igniter.
How do I reset the heating element in a dryer?
First, look for a red reset button. It is on the heating element housing or on the thermal fuse at the back of the dryer. Press the button until you hear a click. If the dryer still is not heating up, the heating element must be replaced because it is faulty.
Is it worth fixing a 7 year old dryer?
A 7-year-old dryer is worth fixing. The common rule is to replace it only if the repair cost exceeds 50% of the price of a comparable new model.
What is the most expensive part of a dryer?
The most expensive parts to replace are the motor and the electronic control board.
How to clean a dryer filter?
The filter should be cleaned after every use by simply pulling off the visible lint by hand. Additionally, you should deep-clean the screen every few months by washing it with warm water and soap.
