Quick answer

Turn off the dryer and unplug it. Check the thermal fuse and heating element for damage. Replace faulty parts if needed.

Confirm the symptom

Clothes remain damp after a full cycle
Dryer runs but no heat is felt
Timer knob spins freely without resistance

Tools and prep

Screwdrivers (flathead and Phillips)
Multimeter for testing continuity
Owner's manual for part diagrams
Work gloves and safety glasses
Empty laundry load for testing

Step-by-step troubleshooting

Check Power Supply
Do: Verify the dryer is properly plugged in and the circuit breaker hasn't tripped.
Observe: Power indicator lights or motor hum when turned on.
Means: Power is reaching the dryer.
Next: Test the heating element.
Test the Heating Element
Do: Unplug the dryer. Locate the heating element and use a multimeter to check for continuity.
Observe: Multimeter shows no continuity.
Means: Heating element is faulty and needs replacement.
Next: Replace the heating element.
Inspect the Thermal Fuse
Do: Locate the thermal fuse (usually near the exhaust duct). Test it with a multimeter.
Observe: No continuity in the thermal fuse.
Means: Thermal fuse is blown; replace it.
Next: Replace the thermal fuse.
Check the Thermostat
Do: Test the thermostat with a multimeter. Ensure it closes the circuit when cold.
Observe: Thermostat does not close the circuit.
Means: Thermostat is faulty and should be replaced.
Next: Replace the thermostat.
Examine the Gas Valve (Gas Dryers)
Do: Check for gas leaks and ensure the gas valve is open. Test the gas valve coil.
Observe: Gas valve coil shows no continuity.
Means: Gas valve is faulty and needs replacement.
Next: Replace the gas valve coil.
Inspect the Vent System
Do: Check for clogged vents or excessive lint buildup in the exhaust duct.
Observe: Lint is blocking airflow or the vent is restricted.
Means: Clean the vent system thoroughly.
Next: Clean the vents and test the dryer again.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Faulty Heating Element The heating element is damaged or burned out, preventing heat generation.	Common	Medium	Heating Element
Blown Thermal Fuse Overheating or a previous fire can blow the thermal fuse, cutting off power to the heating system.	Common	Easy	Thermal Fuse
Failed Thermostat A malfunctioning thermostat fails to regulate heat, causing the dryer to stop heating.	Sometimes	Medium	Thermostat
Gas Valve Issues (Gas Dryers) A faulty gas valve or coil prevents gas from reaching the burner.	Sometimes	Hard	Gas Valve Coil
Clogged Vent System Restricted airflow from lint buildup can cause overheating and safety shutdowns.	Sometimes	Easy	Vent Cleaning Kit
Tripped Circuit Breaker An electrical overload can trip the circuit breaker, cutting power to the heating element.	Rare	Easy	None

Common replacement parts for a dryer not getting hot include:

Heating Element
Thermal Fuse
Thermostat
Gas Valve Coil (for gas dryers)
Vent Cleaning Kit

Always refer to your dryer's model number when ordering replacement parts to ensure compatibility.

When to call a professional

You smell gas or suspect a gas leak
You're uncomfortable working with electrical components
The dryer still doesn't heat after replacing all common parts
The dryer is under warranty and you don't want to risk voiding it

FAQ

How often should I clean my dryer vent?

Clean the vent at least once a year, or more frequently if you dry heavy lint-producing fabrics.

Can a tripped circuit breaker cause a dryer to stop heating?

Yes, if the circuit breaker is tripped, the dryer may run but not generate heat. Check and reset the breaker if needed.

Is it safe to replace the thermal fuse myself?

Yes, replacing the thermal fuse is a simple task with basic tools. Ensure the dryer is unplugged before starting.

Why would the thermal fuse blow?

A blown thermal fuse is usually caused by overheating, often due to a clogged vent or a failed heating element.

Can a faulty thermostat cause the dryer to stop heating?

Yes, if the thermostat is defective, it may not allow the heating element to activate, resulting in no heat.
