Quick answer

If your dryer doesn't get hot, first check the power source and heating element. Turn off the power, inspect the element for breaks, and replace if needed. For gas dryers, ensure the gas valve is open and the igniter is working.

Confirm the symptom

Dryer runs but clothes remain damp
No heat coming from exhaust vent
Dryer makes noise but no warmth
Clothes take longer than usual to dry

Tools and prep

Screwdriver set (flathead and Phillips)
Multimeter for electrical testing
Owner's manual for dryer model
Replacement heating element or igniter (if needed)
Work gloves for safety
Ensure dryer is unplugged or gas is turned off before starting

Step-by-step troubleshooting

Check Power Source
Do: Verify the dryer is properly plugged in and the circuit breaker hasn't tripped.
Observe: Power indicator or motor runs but no heat.
Means: Power issue or faulty heating component.
Next: Test heating element or igniter
Inspect Heating Element
Do: Unplug the dryer and access the heating element. Look for visible breaks or burns.
Observe: Broken or discolored element.
Means: Heating element is damaged.
Next: Replace heating element
Test Thermostat
Do: Use a multimeter to check continuity in the thermostat.
Observe: No continuity or erratic readings.
Means: Thermostat is faulty.
Next: Replace thermostat
Check Gas Valve (Gas Dryers)
Do: Ensure the gas valve near the dryer is fully open.
Observe: Gas valve is closed or partially closed.
Means: Gas supply is restricted.
Next: Open gas valve and test dryer
Inspect Igniter (Gas Dryers)
Do: Look at the igniter for cracks or damage. Test with multimeter if necessary.
Observe: Igniter is cracked or not glowing.
Means: Igniter is faulty.
Next: Replace igniter
Clean Vent and Lint Filter
Do: Remove lint from the lint filter and clean the exhaust vent thoroughly.
Observe: Excessive lint buildup or blockage.
Means: Blocked vent reduces heat efficiency.
Next: Dry a small load to test
Test Thermal Fuse
Do: Use a multimeter to check if the thermal fuse has continuity.
Observe: No continuity in the thermal fuse.
Means: Thermal fuse is blown.
Next: Replace thermal fuse

Common causes

Cause	Likelihood	Difficulty	Part often needed
Faulty Heating Element The heating element is broken or burned out, preventing heat generation.	Common	Easy–Medium	Heating element
Blown Thermal Fuse A thermal fuse cuts power if the dryer overheats, and it cannot reset itself.	Common	Easy	Thermal fuse
Faulty Thermostat A malfunctioning thermostat may not allow the heating element to activate.	Sometimes	Easy–Medium	Thermostat
Clogged Vent or Lint Filter Blocked airflow can reduce drying efficiency and heat output.	Sometimes	Easy	N/A
Gas Valve Closed (Gas Dryers) Gas supply is restricted if the valve is not fully open.	Sometimes	Easy	N/A
Faulty Igniter (Gas Dryers) A damaged igniter cannot ignite the gas, preventing heat.	Sometimes	Medium	Igniter
Tripped Circuit Breaker The dryer's circuit may have tripped, cutting power to the heating element.	Sometimes	Easy	N/A
Wiring Issues Loose or damaged wiring can prevent the heating element from receiving power.	Rare	Hard	Wiring kit or electrician service

Parts matching

Common replacement parts for a dryer that doesn't get hot include:

Heating element for electric dryers
Thermal fuse
Thermostat
Igniter for gas dryers
Gas valve coil (if applicable)

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

When to call a professional

If the dryer still doesn't heat after replacing the heating element or igniter
If you're uncomfortable working with electrical components or gas lines
If the dryer is under warranty and DIY repairs may void it
If the problem involves complex wiring or gas connections

FAQ

How do I know if my dryer's heating element is bad?

Inspect the heating element for visible breaks or burns. If it's damaged or shows no continuity with a multimeter, it needs replacement.

Can a clogged vent cause my dryer to not get hot?

A clogged vent can reduce airflow and efficiency, but it typically doesn't prevent heat entirely. However, it can cause overheating and trip the thermal fuse.

Why is my gas dryer not igniting?

A faulty igniter or closed gas valve is usually the cause. Check the igniter for cracks and ensure the gas valve is fully open.

Is it worth repairing an old dryer that doesn't get hot?

If the repair cost is less than 50% of a new dryer's price and the unit is otherwise reliable, repair is usually worth it.
