The dryer is equipped with a thermal fuse on the exhaust fan housing. To access the thermal fuse, the dryer must be disassembled.
Remove the lower bezel and look for this thermal fuse. It’s on the fan case, unplug and secure the two wires together, plug them back in and test the dryer if it starts, then replace the thermal fuse.
Thermal fuses are installed on the dryer outlet duct. Usually you have to remove the back cover of a dryer to get to the fuse. Make sure the dryer is off before trying to locate and repair the fuse.
Touch the left multimeter lead on the left side of the thermal fuse, touch the right multimeter lead on the right side of the fuse. Keep an eye on the multimeter needle, a needle that doesn’t move indicates a blown thermal fuse. If so, don’t worry, replacing the thermal fuse is an easy task.
Resetting a thermal fuse
- Unplug the dryer from the outlet.
- Rotate the faceplate towards you so that you can look around the room.
- Point a flashlight at the flat side to locate the blown thermal fuse.
It’s a good deal and we have 3 fuses. In stock. This thermal fuse is exactly what I needed to turn the dryer back on. Most selected products and reviews.
The thermal fuse is a safety component that intervenes if the air flowing through the dryer is overheated. These steps replace the thermal fuse on Kenmore, Whirlpool, Maytag, Amana, Roper, Crosley, and Estate electric dryers with a lint filter at the top of the cabinet.
If the fuse blows, the dryer may operate but not heat up, if at all. Usually the fuse blows when the air flow is restricted (blocked vent, lint accumulation in the dryer, etc.), but it could also be due to a short heating element, a faulty control board, etc.
The dryer does not have a reset button. I recommend placing the two (2) switches in the dryer cabinet and resetting both switches by turning them off and back on 23 times and then checking that the dryer starts up.

If a tumble dryer’s thermal fuse blows, the tumble dryer often stops heating the laundry while drying. To determine if the problem is with the blown thermal fuse or something else, remove the thermal fuse and let the dryer run normally. If the dryer starts to heat up again, you will know that the thermal fuse has blown.
Many dryers are equipped with a reset button on the control panel. If the motor does not run, let the dryer cool down for about ten minutes. Then press the reset button. If there are no problems with the motor, switches or electrical system, the dryer must be restarted.
The main cause of the thermal fuse melting is limited air flow. Check the drain path at the outlet of the drain hose for excessive lint or debris. Check the impeller to make sure it is not damaged or blocked. This can be done in cooling or ventilation mode.
Usually the bicycle thermostat controls the activation and deactivation of the heating element. If the bicycle thermostat remains in the open position, the dryer will ■■■■ out cold air. In some cases the high limit thermostat is a thermal fuse, if that thermal fuse is blown the dryer will ■■■■ cold air.
How can I check a dry fuse
How to check if the thermostat is working:
Common tumble dryer problems include a faulty door switch or starter switch, and operational problems such as a faulty tumble dryer or electronic control board - if the drum light does not go out, this is likely to be the cause of the failure. starting the dryer. A blown thermal fuse often prevents an electric dryer from starting.
Problem: the dryer does not start
