- Check the cycle first – Some cycles (air fluff, eco, delicate) don’t use heat. Always test with a normal or high-heat cycle before troubleshooting further.
- Clean the lint filter – Even a thin, waxy film from fabric softener can restrict airflow and trigger safety cutoffs. Wash the filter with warm water and dish soap if needed.
- Inspect the venting – Crushed, kinked, or excessively long vent runs cause overheating and shut the heater off. Disconnect the vent briefly and test: if heat returns, the vent is the problem.
- Reset the breakers – Electric dryers use a 240V, two-pole breaker. One side can trip while the drum still turns, leaving you with no heat. Turn the breaker fully OFF, then back ON.
- Check for error codes – If your dryer displays a fault code, note it before unplugging. Codes often point directly to heating or airflow issues and speed up diagnosis.
What fails most often on electric dryers?
Heating elements, thermal cutoffs/fuses, high-limit thermostats, and wiring connections. Repeated overheating usually means an airflow restriction rather than a bad part.
Safety tips: Always unplug the dryer before opening panels. Use a non-contact voltage tester. Never run the dryer with the vent removed longer than a short test - lint and moisture can build up quickly.
When to call a technician: Breakers that keep tripping, visible scorch marks, burning smells, or heaters that fail repeatedly. These indicate airflow problems or electrical faults that require proper testing.
