How To Know if Your Dryer Has a Faulty Thermostat

A dryer thermostat plays a critical role in regulating temperature and preventing overheating. When the thermostat malfunctions, it can lead to inefficient drying, overheating, or no heat at all. If your dryer isn’t working correctly, the thermostat may be to blame. Here’s how to identify a faulty dryer thermostat and what you can do about it.

What Does a Dryer Cycling Thermostat Do?

A dryer cycling thermostat helps maintain a consistent temperature inside the dryer drum. It works by:

• Sensing the temperature inside the dryer.
• Turning the heating element on and off to prevent overheating.
• Ensuring clothes dry evenly without excessive heat damage.

Most dryers have at least one thermostat, but some models include multiple thermostats for different functions, such as a high-limit thermostat for extra safety.

How to Know if the Dryer Thermostat is Bad

A faulty thermostat can cause several issues, including:

• Clothes taking too long to dry – If the thermostat isn’t regulating heat properly, drying cycles may last longer than usual.
• Overheating dryer – If the thermostat fails to shut off the heat, the dryer may become dangerously hot.
• No heat at all – A broken thermostat can also prevent the heating element from turning on, leaving clothes damp.
• Burning smell – Excessive heat from a malfunctioning thermostat can cause a burnt odor inside the dryer.

Testing the Thermostat

If you suspect your dryer thermostat is faulty, you can test it with a multimeter:

1. Unplug the dryer and locate the thermostat (usually behind the back panel).
2. Remove the thermostat and set the multimeter to the continuity setting.
3. Place the probes on the thermostat terminals — if there’s no continuity, the thermostat is defective.

If the thermostat fails the test, it will need to be replaced.

What if My Dryer Doesn’t Have a Thermostat?

Some modern dryers don’t use traditional thermostats and instead rely on electronic temperature sensors. These sensors serve the same function but may also fail, leading to:

• Inconsistent heating
• Long drying times
• Unexpected shut-offs

If your dryer has digital temperature controls, you may need a professional to diagnose and repair the issue.

How to Keep the Dryer Heating Correctly

To prevent thermostat failures and keep your dryer working efficiently:

• Clean the lint filter after every load – A clogged lint filter can cause the dryer to overheat.
• Check and clean dryer vents regularly – Blocked vents can force the dryer to work harder, damaging the thermostat.
• Avoid overloading the dryer – Too many clothes can lead to uneven heating and put strain on the thermostat.
• Schedule regular maintenance – Having a professional inspect your dryer can prevent unexpected breakdowns.
