Rheem 70-20602-01K Blower Wheel

This part is designed for select Rheem and Ruud HVAC systems. To confirm compatibility, check your existing blower wheel for the part number 70-20602-01K or consult your furnace's service manual to ensure your unit requires an 11-inch by 10-inch wheel with a 1/2-inch bore.

Yes, rotation is critical. This specific wheel is engineered for clockwise (CW) rotation. Installing a wheel with the incorrect rotation will prevent your system from moving air effectively and could potentially damage your blower motor.

While the dimensions may match, it is generally recommended to replace your blower wheel with the same material type specified by the manufacturer. Metal wheels are durable, but they have different weight and balance characteristics than plastic versions, which can affect motor performance if not intended for your specific blower assembly.

A rattling or vibrating sound often indicates that your current blower wheel is either damaged, dirty, or out of balance. If the wheel is physically bent or has lost its balancing clips, replacing it with this new unit should restore quiet, smooth operation.

You will typically need basic hand tools, such as a screwdriver and a hex key (Allen wrench) to loosen the set screw on the motor shaft. Because the blower assembly is located inside the furnace cabinet, ensure the power is completely disconnected before attempting any repairs.
