Rheem-Ruud 70-101087-81 Induced Draft Blower

The Rheem-Ruud 70-101087-81 Induced Draft Blower is a critical 120V combustion safety component designed for precise flue gas evacuation in residential furnaces. This OEM assembly features a 1/50 HP shaded pole motor operating at 3000 RPM, engineered specifically for right-hand discharge configurations. As a high-performance furnace inducer motor replacement, this unit ensures the pressure switch remains closed by pulling combustion air through the heat exchanger, a necessity for high-efficiency systems where natural draft is insufficient. Built with durable sheet metal housing and high-grade ball bearings, this 70-101087-81 draft inducer serves as a direct drop-in for Fasco 7121-11559 and legacy part numbers 70-24175-81 and 70-24175-01. The package includes the necessary mounting gasket to ensure a secondary seal against the collector box, preventing leakages that compromise CO safety. It is designed for single-stage heating applications and features automatic thermal overload protection to prevent motor burnout during extended run cycles. This is the standard exhaust venter motor for modern Hot Surface Ignition (HSI) and direct spark systems.

• Direct Compatibility: Replaces Rheem 70-24175-81 and Fasco 7121-11559 without field modification.
• High-Efficiency Performance: 3000 RPM motor maintains the static pressure required to clear secondary heat exchangers.
• Contractor Grade: Includes a high-temp gasket and features a standard 120V, 0.60 Amp draw for universal serviceability.
• Quiet Operation: Precision-balanced blower wheel reduces vibration and resonance through the ductwork.

Common Questions

Is this compatible with standing pilot furnaces?
No. This specific model (70-101087-81) does not include the pilot tubing port. For older standing pilot systems, a different assembly with the integrated port is required.

Does this unit include the mounting gasket?
Yes, the 68-22850-01 mounting gasket is included to ensure an airtight seal between the blower housing and the furnace collector box.

Will this fix a code 31 or pressure switch stuck open error?
If your inducer motor is failing to reach the proper RPM or the bearings are seized, replacing it with this OEM unit typically resolves pressure switch-related lockout codes.
