Quick answer

First, check the power supply and ensure the dryer is plugged in. Clean the lint trap and vent to remove blockages. If the dryer still doesn’t work, test the thermal fuse and motor.

Confirm the symptom

Dryer won't start or heat
No power to the dryer
Dryer runs but doesn't dry clothes

Tools and prep

Screwdriver (flathead and Phillips)
Multimeter for testing electrical components
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: Dryer powers on when outlet and breaker are functional.
Means: Power issue resolved if outlet and breaker are working.
Next: If power is confirmed, move to the next step.
Clean Lint Trap and Vent
Do: Remove and clean the lint trap. Use a vacuum or brush to clear lint from the vent duct.
Observe: Dryer heats and operates normally after cleaning.
Means: Blockage was preventing proper airflow and heating.
Next: If dryer still doesn't work, proceed to the next step.
Test Thermal Fuse
Do: Locate the thermal fuse (usually near the exhaust duct). Use a multimeter to test for continuity.
Observe: Multimeter shows no continuity if the fuse is blown.
Means: Blown thermal fuse stops the dryer from heating.
Next: Replace the thermal fuse if it’s blown.
Inspect Motor and Drum Movement
Do: Manually turn the drum to check for resistance. Listen for motor sounds when starting the dryer.
Observe: Drum turns freely and motor makes normal sounds.
Means: Motor and drum are functioning properly.
Next: If motor is not working, test it with a multimeter.
Test Motor with Multimeter
Do: Unplug the dryer. Disconnect the motor and use a multimeter to test for continuity.
Observe: Multimeter shows no continuity if the motor is faulty.
Means: Faulty motor needs replacement.
Next: Replace the motor if it’s faulty.
Check Door Switch
Do: Ensure the dryer door is fully closed. Test the door switch with a multimeter for continuity.
Observe: Multimeter shows continuity when the door is closed.
Means: Door switch is functioning properly.
Next: If the switch is faulty, replace it.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Power Supply Issue Dryer not receiving electricity due to outlet or circuit problems.	Common	Easy	None
Clogged Lint Trap or Vent Blocked airflow prevents proper heating and drying.	Common	Easy	None
Blown Thermal Fuse Overheating or blockage triggers the thermal fuse to blow, cutting power to the heating element.	Common	Easy–Medium	Thermal Fuse
Faulty Motor Motor failure prevents the drum from turning or heating.	Sometimes	Medium	Motor
Faulty Door Switch Door switch not closing properly stops the dryer from operating.	Sometimes	Easy–Medium	Door Switch
Tripped Circuit Breaker Inside Dryer Internal breaker trips due to overload or malfunction.	Rare	Medium	Circuit Breaker
Faulty Timer or Control Board Malfunctioning timer or control board prevents the dryer from starting or cycling properly.	Rare	Hard	Timer or Control Board

Parts matching

If you need to replace parts, match these common components:

Thermal Fuse: Usually located near the exhaust duct. Replace if blown.
Door Switch: Located near the door opening. Replace if continuity test fails.
Motor: Large component connected to the drum. Replace if no continuity or makes unusual noises.
Circuit Breaker: Often found near the heating element. Replace if tripped or faulty.
Timer/Control Board: Central control unit. Replace if other tests don’t resolve the issue.

Purchase replacement parts specific to your dryer model for compatibility.

When to call a professional

If you're not comfortable working with electrical components
If the dryer still doesn't work after replacing all common parts
If the issue involves the control board or complex electrical systems
If the dryer is under warranty and you don’t want to risk voiding it

FAQ

Why is my dryer not getting power?

Check the outlet, circuit breaker, and power cord for issues. A blown thermal fuse can also cut power to the dryer.

How do I know if the thermal fuse is blown?

Use a multimeter to test for continuity. No continuity means the fuse is blown and needs replacement.

Can a clogged vent cause the dryer to stop working?

Yes, a clogged vent can prevent proper airflow, causing overheating and triggering the thermal fuse to blow.

Why is the dryer running but not drying clothes?

This is often due to a clogged vent or a faulty heating element. Check both for blockages or damage.

How often should I clean my dryer vent?

Clean the lint trap after each use and the vent duct at least once a year to prevent blockages.
