Rheem-Ruud 70-22165-81 Draft Blower

The Rheem-Ruud 70-22165-81 Draft Blower is a precision-engineered 120V induced draft motor designed for high-efficiency gas furnaces. This centrifugal blower assembly plays a critical role in the combustion process by exhausting flue gases and ensuring the pressure switch closes to initiate the ignition sequence. Featuring a durable shaded pole motor design, the 70-22165-81 induction fan is built to withstand high static pressure and heat cycles common in residential HVAC systems. This OEM replacement part includes a pre-applied mounting gasket to ensure a gas-tight seal against the collector box, preventing CO leakage and maintaining optimal furnace venting performance. Contractors choose this specific Rheem-Ruud blower assembly for its exact fitment and reliable RP-70-22165-81 compatibility, eliminating the vibration and mechanical noise often associated with universal aftermarket alternatives. Ensure the capacitor and housing are inspected during installation for maximum system longevity.

• Ensures consistent combustion air flow for reliable ignition cycles.
• Includes a critical sealing gasket for a professional, leak-free installation.
• Direct OEM replacement ensures mounting holes and wiring harnesses align perfectly.
• Constructed with a heavy-duty housing to resist corrosion from acidic condensate.
• Optimized for 120V HVAC motor configurations common in Rheem and Ruud platforms.

Will this blower resolve a pressure switch lockout?
If the existing motor fails to reach the required RPM or has a failing bearing, it will not pull sufficient vacuum to close the pressure switch. Replacing it with this 70-22165-81 assembly typically restores the necessary induced draft to clear lockout codes.

Does this unit require a separate capacitor?
This 120V draft inducer is a shaded pole design, meaning it generally does not require an external start/run capacitor, simplifying the electrical hookup during field replacement.

Is the gasket necessary for the install?
Yes. Using the provided high-temp gasket is mandatory to prevent combustion byproducts from escaping the blower housing into the mechanical room or living space.
