Quick answer

If your dryer won't run, first check the power supply and lint trap. Ensure the dryer is properly plugged in and the circuit breaker hasn't tripped. If the vent is clogged, clean it out to restore airflow and function.

Confirm the symptom

Dryer does not start when turned on
No heat or drum movement
Dryer makes no noise when powered on

Tools and prep

Screwdriver set
Multimeter
Lint brush or vacuum
Work gloves
Turn off power at the circuit breaker before starting

Step-by-step troubleshooting

Check Power Supply
Do: Verify the dryer is plugged in and the outlet is working. Check the circuit breaker for tripped switches.
Observe: Outlet has power and breaker is on
Means: Power supply is not the issue
Next: Check Lint Trap and Vent
Check Lint Trap and Vent
Do: Clean the lint trap and use a vacuum to clear the vent duct. Ensure the vent is not blocked.
Observe: Lint trap is clean and vent is clear
Means: Clogging is resolved
Next: Test Dryer Operation
Test Dryer Operation
Do: Plug in the dryer and turn it on. Select a drying cycle and observe if it starts.
Observe: Dryer starts and runs normally
Means: Issue was resolved
Next: End
Inspect Dryer Drum
Do: Check for any obstructions in the drum. Ensure the drum rotates freely by hand.
Observe: Drum spins without resistance
Means: Drum is not jammed
Next: Check Thermal Fuse
Check Thermal Fuse
Do: Locate the thermal fuse (usually on the exhaust duct) and test it with a multimeter for continuity.
Observe: Multimeter shows continuity
Means: Thermal fuse is working
Next: Check Dryer Motor
Check Dryer Motor
Do: Test the motor with a multimeter for continuity. If no continuity, the motor may need replacement.
Observe: Motor has continuity and operates when powered
Means: Motor is functioning
Next: End
Check Dryer Timer
Do: Test the timer with a multimeter to ensure it's sending power to the motor and heating element.
Observe: Timer shows continuity and sends power
Means: Timer is working
Next: End

Common causes

Cause	Likelihood	Difficulty	Part often needed
Clogged Lint Trap or Vent Blocked airflow can prevent the dryer from operating safely.	Common	Easy	None
Tripped Circuit Breaker A tripped breaker cuts power to the dryer.	Common	Easy	None
Faulty Thermal Fuse A blown thermal fuse stops the dryer to prevent overheating.	Sometimes	Easy–Medium	Thermal Fuse
Broken Dryer Drum A jammed or broken drum prevents rotation and operation.	Rare	Medium	Drum Roller or Idler Pulley
Faulty Dryer Motor A failed motor stops the drum from spinning and heating.	Sometimes	Hard	Dryer Motor
Malfunctioning Dryer Timer A faulty timer can't send power to the motor or heating element.	Rare	Medium	Dryer Timer

Parts matching

If you need parts for your dryer, match these common components to your model:

Thermal Fuse – usually located near the exhaust duct
Dryer Motor – found at the bottom of the dryer
Drum Roller – supports the drum and allows it to rotate
Idler Pulley – keeps tension on the drive belt
Dryer Timer – controls the drying cycle and power distribution

Always refer to your dryer's manual for specific part locations and compatibility.

When to call a professional

If the dryer still doesn't run after checking all steps
If you're unsure about electrical components or motor replacement
If you detect gas leaks or strong odors (for gas dryers)
If the dryer makes unusual noises or sparks during operation

FAQ

Why is my dryer not getting power?

Check the power cord, outlet, and circuit breaker. Ensure the dryer is properly plugged in and the breaker hasn't tripped.

Can a clogged vent stop the dryer from working?

Yes, a clogged vent can cause the dryer to shut down to prevent overheating or fire hazards.

How do I test the thermal fuse?

Use a multimeter to check for continuity. If there's no continuity, the thermal fuse is blown and needs replacement.

What if the dryer motor is making noise but not running?

The motor may be damaged or the belt could be broken. Check the motor and replace if necessary.
