Why Is My Dryer Not Heating? Common Causes and Fixes

The short version: when a dryer tumbles but won't heat, the usual causes are a clogged vent, a blown thermal fuse, a failed heating element (electric), or a bad igniter (gas). Clean the vent first; the failed parts are covered by a home warranty with appliance coverage.

First, the safety check

A clogged dryer vent is the most common cause — and a fire risk. Clean the lint screen every load and the vent duct regularly. A blocked vent makes the dryer overheat and trip its safety fuse.

Common causes a dryer won't heat

1. Clogged vent / lint buildup — overheats and cuts the heat.
2. Blown thermal fuse — a safety fuse that trips (often from a clogged vent) and stops the heat.
3. Failed heating element (electric dryers).
4. Bad igniter or gas valve (gas dryers).
5. Faulty thermostat or thermal cutoff.
6. Broken timer or control board.

When a home warranty covers it

Mechanical and electrical failures — heating element, igniter, thermostat, thermal fuse, control board — are covered on plans that include the dryer (usually a Total Plan or add-on). You file a claim, a technician is dispatched, you pay the service fee. See does a home warranty cover washer and dryer. Not covered: a dryer that failed from a neglected, clogged vent (that's maintenance).

Key takeaways

• Clean the vent first — a clog is the top cause and a fire risk.
• Heating element, igniter, thermostat, and fuse failures are covered on plans with the dryer.
• Failure from a neglected vent may be denied as lack of maintenance.

Frequently asked questions

Why is my dryer running but not drying? Usually a clogged vent, a blown thermal fuse, or a failed heating element or igniter. Clean the vent first, then check the heat source.

Does a home warranty cover a dryer heating element? Yes, on plans that include the dryer — a failed element from normal wear is repaired or replaced up to your plan's terms.
