Hotpoint Dryer Thermal Fuse

A one-shot safety device that blows if the dryer overheats, cutting power to the heater.

DifficultyEasy to moderate

Typical time20 to 45 minutes

ToolsScrewdriver or nut driver, Multimeter

Safety. Unplug the dryer before you start (and switch off the breaker if it is hard-wired). A blocked vent is a fire risk, so always clear the cause of any overheating.

Signs it has failed

The dryer runs but there is no heat
The dryer will not start at all on some models
A recent history of long drying times or a hot, blocked vent
No continuity across the fuse when tested

Check before you buy

Test the fuse with a multimeter: a blown fuse reads open
Find out why it blew: a blocked lint trap, crushed vent hose or blocked outside vent
Test the heating element and thermostat too

What replacing it fixes: if the signs above match your dryer and the checks point to this part, fitting a new one should clear those faults. If the symptoms continue, the cause is elsewhere (a control board, a sensor or a blocked vent or hose).

How to replace it

Unplug the dryer
Remove the rear or lower panel and find the fuse on the blower housing or heater box
Pull off the two terminals and release the old fuse
Fit the new fuse and reconnect the terminals
Clear the vent and test the dryer

Guide steps are typical for this type of part. Layouts differ between models, so follow your own manual where it differs.

Getting the right part

Thermal fuses are rated by temperature and shape. Match the OEM part number and do not bypass or substitute a fuse.

Check your model number first. It is on the rating plate — usually inside the door frame, on the back or side panel, or inside the appliance. Parts that look identical often differ by model, so match the number to the listing before you order.
