Why does my dryer thermal cutoff keep 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.

Why does my dryer thermostat keep tripping?

A further issue associated with clogged filters is that they can cause the thermostats to trip. This is because as the filter becomes clogged, the airflow around the appliance is reduced due to cooler air not being circulated. If the temperature rises too high in the tumble dryer, the thermostat will trip.

How do you reset a dryer thermal switch?






Quote from Youtube video: So if you have this issue and you keep spot or you trip this you may want to try drilling this. And then you got a little bit of pressure. And it resets. It. So if you're testing your dryer.

How do you bypass thermal cutoff on dryer?

Locate and Bypass the Fuse



The thermal fuse will look like a thin strip of white plastic with a wire coming out of each end. In order to bypass the thermal fuse, use electrical tape to tape the two ends together. The thermal fuse will then be bypassed. Turn the dryer on to a heat cycle for no more than 90 seconds.

Why does the thermal fuse keep blowing on Samsung dryer?

Dryer Hose or Vent Line Clogged



This is the most common reason a thermal cutoff fuse keeps tripping. You need to remove the vent line from the back of your dryer and clean it out.

What is a dryer thermal cutoff?

The thermal cut-off (Dryer Thermal Cut-Off Fuse Kit, Dryer Thermal Cut-Off Kit) prevents the dryer from overheating when the dryer high limit thermostat fails in a closed circuit condition.

How do I stop my dryer from tripping the breaker?





Dryer Keeps Tripping Breaker? Here’s What to Do

  1. Check the Heating Element.
  2. Check the Heating Element Assembly.
  3. Check the Drive Motor.
  4. Check the Terminal Block.
  5. Replace the Circuit Breaker.


Will the dryer run if the thermal fuse is blown?

Will the dryer run if the thermal fuse is blown? Unlike a thermostat that can reset itself, once a dryer thermal fuse blows, it will need to be replaced with a new one before the dryer will run.

What does a thermal cutoff fuse do?

Thermal Cutoffs (Thermal Fuses) are devices designed to keep components safe in situations when an excessive temperature occurs. When the rated functioning temperature of the thermal cutoff is exceeded, the device will fail open in the electrical circuit, breaking the flow of current.

How do I know if my dryer thermal fuse is blown?



To test if your thermal fuse has blown, touch the right side of your multimeter lead to the right side of the fuse, and repeat with the left multimeter lead. If the multimeter needle fails to move, this indicates the thermal fuse has blown.

What blows a thermal fuse on a dryer?

A thermal fuse will blow when the temperature gets too high, not when it’s drawing too much current. When it blows, the dryer stops generating heat. It’s necessary to replace it before the dryer will run again. The thermal fuse is different from the thermal cutoff.

How many thermal fuses does a dryer have?

Electric dryers use two household fuses or circuit breakers. The drum can still turn if just one fuse is blown, but there will be no heat. You may need to replace both fuses or reset both circuit breakers. If the dryer’s thermal fuse has blown due to a power surge or other mechanical problem, the dryer won’t heat.

What does thermal fuse do in dryer?



The federal government passed a law several decades ago requiring all clothes dryers – residential and commercial – to include thermal fuses. The thermal fuse acts like a switch, cutting off the flow of electricity when exhaust temperatures reach a certain point to reduce the risk of a fire.

How much does a thermal fuse cost for a dryer?

Other Costs to Fix a Dryer

Part Material Cost Total Cost
Thermal fuse $5 – $10 $80 – $130
Dryer thermostat $3 – $20 $180
Bearing $50 $130 – $250
Roller $10 – $30 $90 – $230

Are dryers worth repairing?

You can generally repair a dryer for $125 vs replacing it for $350. Since there’s little difference in life expectancy between the two options, it’s generally cheaper and more practical to repair a dryer than to replace it.

Where is the dryer thermal fuse located?

Quote from the video:
Quote from Youtube video: Location of the thermal fuse is right on the blower housing.
