In most dryers, no.
If the thermal fuse is blown, the dryer will not start. Pressing the Start button does nothing, even though the control panel may still light up.
For a full overview of symptoms, testing, and replacement, see Dryer Thermal Fuse: Complete Guide (Symptoms, Testing & Replacement).
Why Many Dryers Won’t Start at All
In many models, the thermal fuse is wired into the motor circuit.
When it blows, power to the motor is cut completely. The dryer cannot tumble, and the cycle will not begin.
This is the most common design in Whirlpool, Maytag, and Kenmore-style dryers.
Some Dryers Run but Do Not Heat
In certain models, the thermal fuse only protects the heating element.
If this type of fuse blows:
-
The drum may still turn
-
The timer may advance
-
There is no heat
Clothes will stay wet at the end of the cycle.
This depends on the wiring design of the specific dryer.
What You May Notice
Common signs include:
-
Dryer completely dead when pressing Start
-
Dryer runs but air is cold
-
Dryer stopped suddenly during a previous cycle
-
No clicking or motor sound when attempting to start
These symptoms suggest the fuse may have opened.
How to Be Sure
Symptoms alone are not enough for confirmation.
The only reliable way to know if the thermal fuse is blown is to test it with a multimeter for continuity.
If the fuse shows no continuity, it has failed and must be replaced.
Important Reminder
If the thermal fuse is blown, it usually indicates overheating.
Before replacing it, check for:
-
Blocked lint screen
-
Clogged vent hose
-
Crushed exhaust duct
-
Restricted outside vent flap
Replacing the fuse without correcting airflow problems may cause it to blow again.
