Tools and prep

Screwdriver set
Multimeter
Work gloves
Vacuum with brush attachment
Turn off power at the circuit breaker

Step-by-step troubleshooting

Check Power Source
Do: Verify the dryer is plugged in and the outlet is working.
Observe: Outlet powers other devices.
Means: Power supply is functional.
Next: Check lint trap and vent
Inspect Lint Trap and Vent
Do: Clean the lint trap and use a vacuum to clear the vent duct.
Observe: No lint blockage.
Means: Airflow is restored.
Next: Test thermal fuse
Test Thermal Fuse
Do: Use a multimeter to test the thermal fuse for continuity.
Observe: Multimeter shows no continuity.
Means: Thermal fuse is blown.
Next: Replace thermal fuse
Check Drive Motor
Do: Listen for humming or smell of burning when powering on.
Observe: Motor hums but doesn’t run.
Means: Drive motor is faulty.
Next: Replace drive motor
Examine Door Switch
Do: Ensure the dryer door is fully closed and latched.
Observe: Door switch is engaged.
Means: Door switch is functioning.
Next: Check timer or control board
Check Timer or Control Board
Do: Inspect for visible damage or use a multimeter to test for continuity.
Observe: No continuity or visible damage.
Means: Timer or control board is faulty.
Next: Replace timer or control board

Common causes

Cause	Likelihood	Difficulty	Part often needed

FAQ

How often should I clean my dryer’s lint trap?

Clean the lint trap after every load to prevent blockages and reduce fire risk.

Can a clogged vent cause the dryer to stop running?

Yes, a clogged vent can restrict airflow, trigger overheating, and blow the thermal fuse.

Where is the thermal fuse located?

The thermal fuse is typically located near the dryer’s exhaust duct or inside the back panel.

How do I know if the drive motor is bad?

If the dryer makes a humming noise but doesn’t spin, the drive motor may be faulty.

Can I reset a blown thermal fuse?

No, a blown thermal fuse must be replaced with a new one.
