Frequently Asked Questions (FAQs)

1. What does a thermal cutoff do?

The term “Thermal Cutoff Switch” generally refers to how the switch is used, ie. It cuts off the current to critical machinery when a temperature limit is exceeded preventing potential burn out or failure.

2. What does a dryer thermal cutoff do?

A dryer's thermal cutoff switch controls the dryer's temperature, and it also monitors the amount of heat it produces. If the dryer drum is spinning but is not producing heat, the thermal cutoff switch may have failed.

3. What causes thermal cutoff blowing?

The number one cause of dryer overheating is poor venting, and while it may be caused by a defective blower motor, it's more often the result of a clogged lint filter or lint-clogged vents. You're especially likely to have clogged vents if your pipes are made with corrugated metal or worse, plastic.

4. How does a thermal cutoff switch work?

A thermal fuse or thermal cutoff is a safety device which open circuits against overheat. It detects the heat caused by the over-current due to short circuit or component breakdown. Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would.
