Samsung dc66-00402a Dryer Idler Pulley

Product Description

The SAMSUNG dc66-00402a is a genuine OEM idler pulley designed for use in Samsung residential dryers. The idler pulley maintains proper tension on the drum drive belt, keeping the belt seated and the drum rotating smoothly during operation. This part does not include a separate bearing assembly. Licensed appliance technicians and experienced service professionals install this component when the original pulley shows wear, cracking, or causes belt slippage, squealing, or drum rotation failure.

This idler pulley is intended for residential dryer applications where the drum drive belt requires consistent tension to function correctly. It is used in drum-driven dryer configurations where belt tension is maintained by a spring-loaded or fixed idler arm assembly. Install this part when diagnosing belt noise, drum drag, or complete drum stop caused by a failed or worn tension pulley.

• Genuine OEM Samsung replacement part — direct fit with no modification required
• Maintains drum belt tension to ensure consistent drum rotation

Compatibility

Installation Notes

Installation should be performed by a qualified appliance technician. Disconnect power to the dryer at the breaker or by unplugging the unit before beginning any disassembly. The drum, front panel, or cabinet may need to be removed to access the idler arm and pulley assembly. Inspect the idler arm, drive belt, and drum glides during the same service call, as these components wear together.
