Allied Air 12W47 Inducer Motor Cmpev Series

Product Description

The ALLIED AIR 12W47 is a combustion inducer motor designed for use in ALLIED AIR CMPEV series gas furnaces. The inducer motor creates the draft necessary to pull combustion gases through the heat exchanger and exhaust them safely out of the flue. It operates at the start of each heating cycle and must run reliably to satisfy pressure switch proving before ignition is allowed. Licensed HVAC technicians install and service this component as part of routine furnace maintenance or when diagnosing induced-draft failures.

This inducer assembly is intended for residential gas furnace applications. It is matched to the CMPEV series furnace platform and is used in typical forced-air heating systems found in residential and light commercial installations. When an inducer motor fails, symptoms typically include pressure switch lockout, no-heat faults, or unusual noise during the pre-purge cycle. Replacing the inducer with the correct OEM-matched assembly restores proper draft and safe furnace operation.

Key Features

• Designed as a direct OEM-style replacement for ALLIED AIR CMPEV series furnaces
• Restores proper induced-draft function for safe combustion gas evacuation
• Critical for pressure switch proving during the ignition sequence
• Matched to the CMPEV platform for proper fit and airflow performance

Compatibility

Designed as an OEM-style replacement inducer motor for ALLIED AIR CMPEV series gas furnaces.

Installation Notes

Inducer motor replacement is performed by a licensed HVAC technician. Before servicing, shut off power to the furnace at the disconnect switch and turn off the gas supply. Follow all applicable local mechanical codes and manufacturer wiring diagrams when reconnecting the motor leads and pressure switch tubing. Verify proper draft and pressure switch operation before returning the furnace to service.
