WHIRLPOOL WED4815EW Dryer Running But No Heat

Dryer Heating Element

The heating element consists of a nichrome wire coil that generates heat through electrical resistance. Forensic analysis often reveals a physical break in the coil caused by mechanical stress from repeated thermal cycling or localized overheating. Once the coil is severed, the circuit is broken, and no heat can be produced despite the dryer drum rotating.

Thermal Cut-off Kit

This kit includes a high-limit thermostat and a thermal fuse located on the heater housing. These components act as a fail-safe that opens the electrical circuit if internal temperatures exceed safety thresholds, typically due to restricted airflow in the exhaust venting. If the fuse 'blows' or the thermostat fails open, power is cut to the heating element while allowing the motor to continue running.

Cycling Thermostat

The cycling thermostat regulates the internal drum temperature by opening and closing the heater circuit throughout the drying cycle. Internal contact pitting or mechanical fatigue of the bimetallic strip can cause the contacts to remain in the 'open' position. This prevents the heating element from energizing even when the dryer is set to a heat cycle.
