PROTECH 70-23641-86 Induced Draft Blower | Includes Gasket | 115V 3000 RPM 0.7 Amp

The 70-23641-86 is a precision-engineered OEM Induced Draft Blower assembly designed to serve as the critical "exhaust system" for Rheem and Ruud gas furnaces. This assembly functions as the primary "brain" for combustion safety, pulling air through the heat exchanger to ensure a proper fuel-to-air mixture before the ignition cycle begins. Specifically optimized for the RGRM, RGRA, and RGLQ series, this factory-authorized PROTECH™ part maintains the negative pressure required to close the furnace pressure switch. Replacing a failing inducer with this genuine kit fixes specific "no-heat" lockout issues and eliminates the high-pitched "bearing squeal" often found in aging motors, ensuring your system operates at peak 80% to 90%+ AFUE efficiency.

Key Features

• Complete OEM Kit: The 70-23641-86 is a direct factory replacement that includes a high-temperature fiber gasket, ensuring a gas-tight seal against the collector box without the need for messy RTV silicone.
• Precision RPM Calibration: Factory-rated at 3000 RPM, providing the exact static pressure needed to satisfy safety switches and prevent "pressure switch open" fault codes.
• Resolved Noise & Vibration: Features a dynamically balanced cooling fan and high-grade internal bearings to fix specific mechanical humming or rattling issues common in older inducer housings.
• Safety Monitoring Integration: Engineered to work seamlessly with the furnace's limit circuit, providing constant airflow to purge the heat exchanger of residual gases before and after each heating cycle.
• Durable Corrosion-Resistant Housing: Constructed from heavy-duty materials to withstand the acidic condensate and high-heat environment of a modern furnace exhaust path.

🛠️ HVAC Depot Pro Tip

Before removing your old draft blower, take a high-resolution picture of the wiring and the vacuum hose connections. For the 70-23641-86 to work correctly, the small rubber pressure switch tubing must be free of cracks and seated tightly on the new housing's nipple. When installing, ensure the old gasket material is completely scraped off the furnace's metal surface to prevent exhaust leaks. After installation, cycle the furnace and watch the pressure switch to verify it closes within seconds of the motor reaching full speed.
