Dryer Not Getting Hot Anymore (Troubleshooting Guide)

On this page

Quick answer

Check the dryer's power source and venting. If those are fine, test the heating element, thermal fuse, and thermostat. Replace any faulty parts.

Check Power Source
Do: Ensure the dryer is properly plugged in and the circuit breaker hasn't tripped.
Observe: Dryer powers on but doesn't heat.
Means: Power supply is likely not the issue.
Next: Check venting
Check Venting
Do: Inspect the dryer vent for blockages and ensure it's not kinked.
Observe: Vent is clear and not obstructed.
Means: Venting isn't the problem.
Next: Test heating element
Test Heating Element
Do: Use a multimeter to test the heating element for continuity.
Observe: Multimeter shows no continuity.
Means: Heating element is faulty and needs replacement.
Next: Replace heating element
Test Thermal Fuse
Do: Locate and test the thermal fuse with a multimeter.
Observe: Multimeter shows no continuity.
Means: Thermal fuse is blown and must be replaced.
Next: Replace thermal fuse
Test Thermostat
Do: Test the thermostat with a multimeter to check for continuity.
Observe: Multimeter shows no continuity.
Means: Thermostat is faulty and needs replacement.
Next: Replace thermostat
Inspect Gas Valve (Gas Dryers)
Do: Check the gas valve for proper operation and gas supply.
Observe: Gas valve is closed or gas supply is off.
Means: Turn on the gas supply or replace the gas valve.
Next: Check for other issues

Cause	Likelihood	Difficulty	Part often needed
Faulty Heating Element The heating element is damaged or burned out and can't generate heat.	Common	Medium	Yes
Blown Thermal Fuse The thermal fuse has melted due to overheating and needs replacement.	Common	Easy	Yes
Faulty Thermostat The thermostat isn't regulating temperature correctly.	Sometimes	Medium	Yes
Gas Supply Issues (Gas Dryers) The gas valve is closed or the gas supply is interrupted.	Sometimes	Easy	No
Blocked Vent Lint buildup in the vent restricts airflow and heat distribution.	Sometimes	Easy	No
Tripped Circuit Breaker The dryer's circuit breaker may have tripped due to an overload.	Rare	Easy	No
Faulty Igniter (Gas Dryers) The igniter is worn or damaged and can't ignite the gas.	Rare	Medium	Yes

Common parts needed for a dryer not getting hot:

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

If you're not comfortable using a multimeter or working with electrical components
If the dryer is under warranty and you don't want to risk voiding it
If the problem persists after replacing all common parts
If you smell gas or suspect a gas leak

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

Yes, a tripped breaker can cut power to the heating element. Check and reset the breaker if necessary.

How often should I clean my dryer vent?

Clean the dryer vent at least once a year to prevent lint buildup and ensure proper airflow.

Can a faulty thermostat cause the dryer to overheat?

Yes, a malfunctioning thermostat can fail to regulate temperature, leading to overheating or no heat.

Is it safe to replace a thermal fuse myself?

Yes, replacing a thermal fuse is a simple task that can be done with basic tools and safety precautions.

What should I do if I smell gas from my dryer?

Stop using the dryer immediately, open windows, and contact a professional technician or gas company.
