Dryer Idler Pulley – Maytag / Whirlpool

The dryer idler pulley maintains tension on the drum belt so the drum can rotate smoothly while the motor runs. A worn wheel or bearing can cause squealing, scraping, belt slipping, poor drum movement, or premature belt wear. This ERP aftermarket pulley is a direct replacement for the listed reference numbers; verify the complete model before ordering.

Installation Guidance

General installation guidance—not a substitute for the appliance service manual. Disconnect power and shut off gas on gas dryers before service access. Follow the model-specific disassembly instructions, support the drum where required, and record belt routing and retainers. Inspect the pulley wheel, bearing, drum supports, belt, and motor pulley for wear. Use only manufacturer-specified lubricant, if required, and reinstall all guards before a controlled test.
