An overheating dryer is a major fire hazard that must be addressed immediately. Always unplug the dryer before troubleshooting or opening any panels.
Air flow blockages
The first thing to check is the lint filter and make sure it's completely empty. If you don't clean the lint filter with every load, it can become filled with debris and stop air from flowing. Next, look into the slot where the filter goes to see if lint has spilled inside.
A reduction of the air flowing through the clothes dryer is the number one cause of a dryer overheating or a dryer not drying properly. If your dryer's internal duct has a blockage, hot air becomes trapped inside the machine.
Overloading the dryer can cause its motor to overheat. If this is the case, allow the motor to cool down for 30 minutes.
The cost of replacing a dryer sensor or thermistor varies based on the model and brand, but typically ranges from $10 to $30 for the part itself.
If the cost of replacing the heating element is significantly less than a new appliance, it might be worth replacing the heating element in your dryer. Older dryers often consume more energy than newer models.
Reset your dryer
Resetting your dryer is easy. Unplug it (or turn off power at the circuit breaker), wait some time for the electrical charge to clear out of the dryer (usually 1 to 5 minutes at most), and then power it up again. That's all it takes to reset.
A: About 4 percent of home fires involve a clothes dryer or washing machine, according to the National Fire Protection Association. Q: How many dryer fires happen per year? A: Each year, clothes dryer fires cause almost 16,000 home fires, resulting in $238 million in property damage and 13 deaths, on average.
Warning Signs That Your Dryer Needs Repair
One significant sign of trouble is when the dryer takes much longer than usual to dry clothes. If you find that your clothes remain damp after a standard cycle, it could signal a faulty heating element or clogged vents.
The cost to replace the heating element in a dryer averages $230 but often ranges from $100 to $350 depending on the machine's age, type, and the nature of the repair work. Whether you have an electric or a gas dryer, its heating element is essential to delivering those fresh, fluffy clothes.
A dryer typically lasts about 12-13 years; however, some dryer manufacturers boast up to a 25-year lifespan. It's important to remember, though, that clothes dryer life expectancy goes hand in hand with how often the dryer is used and how well you maintain the appliance.
A clothes dryer that's hot to the touch indicates dangerous overheating and requires immediate attention. First, stop using the dryer immediately to prevent potential fire hazards. Check the lint trap and remove any visible lint buildup. Inspect the exterior vent for obstructions like bird nests or lint accumulation.
TROUBLESHOOTING WHY A DRYER ISN'T DRYING
Overheated Clothes Dryers Can Cause Fires
Fires can occur when lint builds up in the dryer or in the exhaust duct. Lint can block the flow of air, cause excessive heat build-up, and result in a fire in some dryers.
Additionally, you may notice a burning smell, or notice that your clothes and the outside of the dryer are too hot. If you notice any of these symptoms, or suspect that the airflow may be obstructed, stop the dryer immediately, unplug it, and check the duct and vent when they have had a chance to cool.
Whilst they can start naturally, see Information note - Wildfire, it is estimated that 90% of all wildfires across the globe are caused by humans. About 30% of those are started as a deliberate act of arson, whilst 70% are started accidentally or as a direct result of human carelessness.
Clogged vent most likely caused this. Electrical problem. One of our employees had this issue at an old house, the heating element in a water heater would go out and would back feed voltage to ground. This ended up making the dryer vent like a heating element and would make it glow, eventually catching fire.
Overloading the dryer can cause its motor to overheat. If this is the case, allow the motor to cool down for 30 minutes. You might need to reduce the size of the load—the average washer load will fill the dryer drum 1/3 to 1/2 full.

Age of the Dryer
Age is one of the strongest indicators when deciding between repair and replacement: Under 8 years old: Repairs are usually worthwhile. 8–12 years old: It depends on the repair cost and symptoms. Over 12 years old: Replacement may be more cost-effective (especially after a major failure).
