SAMSUNG DRYER DVE50R5400 NOT HEATING Repair

Electrical Supply to Heating Element

The heating element requires a full 240V supply to generate heat. If one leg of the 240V power is interrupted, either from the wall outlet, the dryer's power cord, or the internal terminal block, the 120V components (motor, control board) will still operate, but the heating element will not energize. This is a common failure point, especially after a mechanical event that could jar connections, and aligns with all other heating components already being replaced.

Main Control Board (Heater Relay)

This relay is responsible for switching the 240V power to the heating element. If the relay contacts are burnt or the coil has failed, the element will not receive power, even if the board is otherwise functional and all other heating components are new.

Internal Wiring Harness Damage

The timing of the failure, immediately after the idler pulley failed and the belt came loose, suggests a possible physical impact. A flailing belt could have damaged or severed a wire within the dryer's internal harness, specifically one carrying power to the heating element. This would create an open circuit, preventing the element from receiving 240V.
