The Whirlpool 349241T is a Genuine Whirlpool OEM dryer drum support roller kit. The rollers support the rear of the dryer drum and allow it to rotate smoothly during operation.
Worn or flat-spotted rollers can contribute to rumbling, knocking, thumping, or uneven drum rotation. The OEM service kit includes two drum support rollers with retaining hardware supplied for service.
Drum roller axles can wear at the same time as the rollers. Inspect both axle surfaces and the drive belt while the dryer is disassembled.
