The drum support roller for your dryer holds the drum in place while the drum turns on the support wheels. The drum roller is round with a bearing in the middle and measures approximately 3 inches in diameter. If the dryer is noisy, won’t tumble, or takes too long to dry, you might need to replace the support roller. It is recommended that you replace both rollers at once. The bearing inside this roller is self-lubricating, so no grease will be required. Please remember to disconnect the power to your appliance before starting your repair. This is a genuine OEM part.
