The thermal fuse is usually mounted near the dryer’s exhaust system.
Its location allows it to monitor air temperature leaving the drum. If temperatures become unsafe, the fuse blows and cuts power.
For a complete overview of symptoms, testing, and replacement, see Dryer Thermal Fuse: Complete Guide (Symptoms, Testing & Replacement).
Most Common Location: Blower Housing
In many rear-access dryers, the thermal fuse is attached to the blower housing.
This is typically found behind the back panel of the dryer, near the bottom.
The fuse is small, usually white plastic, with two wires connected to it.
Near the Exhaust Duct
Some dryers mount the fuse directly on the metal exhaust duct inside the cabinet.
Because overheating often starts with restricted airflow, placing the fuse near the exhaust system allows it to detect excessive heat quickly.
Near the Heating Element Housing
On certain models, especially electric dryers, the fuse may be located near the heating element housing.
This setup protects the heating circuit from extreme temperatures.
Front-Access vs Rear-Access Dryers
Rear-access dryers:
-
Remove the back panel
-
Locate the blower housing near the bottom
Front-access dryers:
-
Remove the lower front panel
-
The fuse is often mounted near the blower assembly inside the cabinet
Always unplug the dryer before removing any panels.
How to Identify the Thermal Fuse
Look for:
-
A small rectangular or oval plastic component
-
Two wire terminals
-
Mounted with one or two screws
-
Positioned along the airflow path
Do not confuse it with:
-
The cycling thermostat
-
The thermal cutoff
-
The high-limit thermostat
These components may look similar but serve different purposes.
If You’re Unsure
If you cannot locate the fuse visually:
-
Check your dryer model number
-
Refer to a parts diagram
-
Look for the fuse along the exhaust airflow path
The fuse is always placed where it can detect high heat conditions.
