Having a dryer that won’t heat up is frustrating. Your laundry stays damp, and your daily routine is thrown off. The good news? Most dryer heating problems are fixable! Below are seven common reasons why your dryer isn’t heating and how to fix them.
1. Blown Thermal Fuse
A thermal fuse prevents overheating, but once it blows, the dryer won’t heat at all.
Symptoms
- Dryer runs but doesn’t produce heat
- No airflow from the exhaust vent
Quick Fix
- Locate the thermal fuse (near the blower housing)
- Test it with a multimeter
- If there’s no continuity, replace it
Expert Tip: “Thermal fuses don’t usually blow on their own. If yours has failed, check for lint buildup or ventilation issues to prevent it from happening again.” – Vagan Shakhnazarov, CEO of Top Appliance Repair
2. Faulty Heating Element
The heating element warms the air inside the drum. Over time, it can burn out.
Symptoms
- No heat production
- Dryer takes an unusually long time to dry clothes
Quick Fix
- Disconnect power and remove the back panel
- Test the heating element for continuity
- If faulty, replace it with a compatible part
Brand-Specific Tip: Samsung and Whirlpool dryers are known for heating element failures. Consider professional dryer repair for these brands.
3. Clogged Dryer Vent
A clogged vent restricts airflow, causing overheating and shutting off the heating function.
Symptoms
- Dryer feels hot but doesn’t dry clothes
- Burning smell from the dryer
Quick Fix
- Disconnect the vent hose and clean out lint buildup
- Check for obstructions in the outside vent cap
- Use a dryer vent cleaning kit every 6 months
Preventative Advice: “Lint buildup is a fire hazard! Make it a habit to clean your lint filter after every load and schedule annual vent cleanings.” – Vagan Shakhnazarov
4. Defective Gas Valve Solenoid (Gas Dryers)
Gas dryers use solenoid coils to control gas flow. When these fail, the dryer won’t heat.
Symptoms
- No heat but the drum tumbles
- Clicking sound but no ignition
Quick Fix
- Locate the gas valve solenoids
- Use a multimeter to check for continuity
- If defective, replace both solenoids
Best Brands for Gas Dryers: Speed Queen, Maytag, and GE gas dryers tend to be more reliable but can still suffer from solenoid failures.
5. Malfunctioning Thermostat
A faulty thermostat can cause the dryer to overheat or not heat at all.
Symptoms
- Dryer cycles on and off too quickly
- Clothes take longer to dry
Quick Fix
- Locate the thermostat (inside the control panel or near the heating element)
- Test it with a multimeter
- Replace it if there is no continuity
Note: Thermostat failures are common in older Whirlpool and Maytag dryers.
6. Power Supply Issues (Electric Dryers)
Electric dryers require 240V to heat. A power issue can cause loss of heating.
Symptoms
- Dryer turns on but doesn’t heat
- One breaker trips while the other remains on
Quick Fix
- Check if the circuit breaker is tripped
- Test the dryer outlet with a voltmeter
- Reset the breaker or call an electrician if needed
Expert Insight: “If your dryer is plugged into a regular 120V outlet, it won’t generate enough power to heat. Always ensure your dryer is properly connected to a 240V supply.” – Vagan Shakhnazarov
7. Worn-Out Igniter (Gas Dryers)
Gas dryers use an igniter to light the burner. If it fails, the dryer won’t heat.
Symptoms
- No heat and no flame visible inside the dryer
- Clicking noise without ignition
Quick Fix
- Remove the dryer panel and locate the igniter
- Test it for continuity
- If defective, replace it
Common Brands Affected: LG, GE, and Samsung gas dryers may experience igniter failure more frequently.
