Understanding the Problem
A dryer that spins but doesn't dry clothes is one of the most common laundry frustrations. The fault can be simple — a clogged vent or full lint screen — or a failing part like a heating element, thermal fuse, moisture sensor, or gas ignition components. Electric and gas dryers fail for different reasons, but poor airflow and failed safety cutouts are frequent culprits across both types. Start troubleshooting by separating airflow problems from heating problems: strong warm airflow out the exhaust points to an electrical or gas ignition problem; weak or no airflow almost always points to a blocked vent, clogged lint trap, or a failing blower/motor. For gas dryers, short cycling or no heat can be caused by a faulty igniter, flame sensor, or gas valve solenoid; for electric dryers check the heating element, thermostats and thermal fuse. Many faults can be verified quickly with a visual inspection and a multimeter continuity test.
Common Symptoms
Runs and tumbles but clothes remain damp; long drying times; dryer hot to touch but not drying; dryer trips circuit or stops mid-cycle; little or no exhaust airflow outside.
Common Causes
- Restricted airflow from clogged lint screen, vent hose, or exterior vent
- Failed heating components (electric heating element, thermal fuse, thermostats) or gas ignition parts (igniter, gas valve solenoids, flame sensor)
- Faulty moisture sensor, timer/control, or weak motor/drum not tumbling properly

Helpful Repair Tip
First check airflow: run the dryer empty for 3–5 minutes, then feel the exhaust outside. If airflow is weak, clean the lint trap and vent before testing electrical components. Use a multimeter to test continuity on the thermal fuse and heating element (electric) or igniter (gas).
Frequently Asked Questions
How can I tell if the problem is the vent or the heating element?
Run the dryer empty for 3–5 minutes. Go outside and feel the exhaust at the vent hood: strong warm airflow indicates the vent is clear and points to a heating or ignition issue; weak or no airflow means a vent/duct blockage or clogged lint screen. For electric dryers, open the back or access panel and test the heating element and thermal fuse for continuity with a multimeter. For gas dryers, observe whether the igniter glows and the burner lights — if the igniter glows but no flame, suspect the gas valve solenoids or flame sensor.
Is it safe to keep using a dryer that isn't drying properly?
No — using a dryer with restricted airflow or failed safety parts increases fire risk and can damage the dryer. If the vent is clogged, stop using the dryer until you clean the lint filter and venting. If testing indicates a blown thermal fuse or other failed safety device, replace the failed part before further use. For gas dryers, stop using the appliance if you smell gas or see incomplete ignition and call a qualified technician.
