This fan wheel is the rotating plastic wheel that moves air through the appliance's exhaust and heat systems, helping maintain proper airflow and cooling. Replacing a worn wheel restores airflow and reduces noise from the blower assembly. What it does:

• Spins in the blower housing to draw and direct air through the unit
• Helps maintain proper airflow for heating, drying or venting cycles
• Worn, cracked or broken wheels can cause rattling, grinding, reduced airflow or overheating
• Restores smooth, balanced operation when installed correctly

• Disconnect power to the appliance before servicing.
• Access may require removing the access panel, blower housing or front panel depending on model—follow your model-specific service instructions.
• Inspect the blower housing and shaft for damage or debris before installing; replace if necessary.
