First identify the exact symptom
A failed heating element and an open thermal fuse do not always produce the same behavior. On many electric dryers, an open element lets the drum run with no heat. Depending on the model, an open thermal fuse may stop the motor completely or interrupt only the heat circuit.
Gas dryers use an igniter, flame sensor, and gas-valve coils instead of an electric heating element, but they still rely on thermal protection and unrestricted airflow.
Safe checks before opening the cabinet
- Reset the double-pole dryer breaker fully off and on. A dryer motor can run on 120 volts while the heater lacks the full 240-volt supply.
- Clean the lint screen and inspect the exterior hood while the dryer runs.
- Straighten crushed flexible duct and stop using plastic or foil transition duct where prohibited.
- Test a timed-dry cycle to separate sensor-dry behavior from a total heating failure.
Never bypass a thermal fuse. It is a one-time safety device, and jumping it can create a fire or shock hazard.
Heating element failure patterns
An element can break open and produce no heat, or sag against its metal housing and heat when it should be off. A technician checks element resistance and verifies that neither terminal is shorted to the heater enclosure.
If the dryer heats continuously, disconnect power and schedule service. A grounded element or stuck control relay can overheat clothing even when airflow is adequate.
Thermal fuse failure patterns
Thermal fuses usually open because excessive temperature reached the blower housing or heater duct. Replacing the fuse without correcting lint buildup, a blocked vent, a weak blower, or a cycling-thermostat fault invites another failure.
The correct diagnosis includes airflow measurement, fuse continuity, operating-temperature checks, and inspection of the complete exhaust path. For thermistor-related codes, see the Whirlpool F3 E2 guide and Maytag F4 E3 airflow guide.
When professional testing is needed
Book dryer repair when the breaker is stable and airflow is clear but heat does not return, or when the dryer will not start after an overheating event. Live-voltage and current tests should only be performed with the cabinet assembled and proper electrical protection.

Frequently Asked Questions About General Dryer
How do I know if my dryer has a bad heating element or a blown thermal fuse?
If your electric dryer tumbles but won't heat, the heating element is likely broken. If a thermal fuse blows, many models won't turn on or spin at all. Our licensed technicians in Port St. Lucie use advanced multimeters to test both components and accurately pinpoint the exact failure.
