Dryer Not Heating? Common Causes and When to Call a Professional in Montgomery County

A dryer that tumbles but doesn't heat is one of the most common calls we get at V&V Appliance Repair. Before you start shopping for a new dryer, know this: most heating problems are fixable, often in a single visit.
Why Your Dryer Isn't Heating
- Clogged dryer vent or lint buildup. This is the number one cause. When airflow is restricted, the dryer overheats and the thermal fuse blows — a safety device that kills the heat. If your dryer worked fine and then suddenly went cold, a clogged vent is the prime suspect. (It's also a fire hazard — the U.S. Fire Administration attributes thousands of house fires a year to dryers.)
- Blown thermal fuse. Once it blows, there's no heat until it's replaced. But replacing the fuse without fixing the airflow problem that caused it means it'll just blow again.
- Failed heating element (electric dryers). The coil that produces heat can break or burn out over time. A technician can test it with a multimeter in minutes.
- Faulty igniter or gas valve solenoids (gas dryers). If your gas dryer tumbles but never gets warm, the igniter may not be lighting the gas — or the solenoid coils may be failing.
- Broken thermostat or timer issues. Less common, but a failed cycling thermostat can prevent the dryer from calling for heat.
What You Can Check Yourself
- Clean the lint filter (every load — really).
- Check that the vent hose behind the dryer isn't crushed or kinked.
- Go outside and feel the exterior vent while the dryer runs. Weak airflow means a blockage.
- Make sure the breaker hasn't tripped (electric dryers need 240V — a half-tripped breaker can let it tumble without heating).
When to Call a Professional
If the basics check out and there's still no heat, it's time for a technician. Heating elements, thermal fuses, igniters, and gas components all require proper testing — and gas dryers should never be a DIY project.
