Utica-Dunkirk 2272156 Inducer Motor Assembly

For contractors servicing Utica or Dunkirk boiler systems, the Utica-Dunkirk 2272156 Inducer Motor Assembly is the critical OEM replacement part required to restore high-efficiency combustion and proper venting. This 120V inducer assembly operates at a high-speed 3450 RPM, generating the precise static pressure needed to pull flue gases through the heat exchanger and close the pressure switch safely. As a genuine factory replacement, this motor is balanced to minimize vibration and resonance throughout the cabinet, providing a quieter operation compared to aged or aftermarket alternatives.

The 2272156 inducer comes as a complete drop-in solution, including the U-shaped metal mounting plate and the replacement gasket for a vacuum-tight seal. Engineered for single-phase operation, it manages the initial purges and continuous draft demands of induced-draft heating configurations. Replacing a seized or noisy motor with this OEM assembly ensures your system meets original manufacturer specifications for airflow and thermal safety, preventing lockout codes related to venting failure.

Key Benefits for Technicians:

• Verified Compatibility: Fits specific Utica and Dunkirk boiler models, including select Dunkirk XEB-4 and Utica CBB series units.
• Complete Assembly: Includes the pre-cut mounting gasket and U-shaped metal plate to eliminate the need for sourcing hardware or using high-temp silicone.
• High-Performance Specs: Technical rating of 120V, 3450 RPM, and approximately 0.6 Amps for consistent draft performance.
• Durable Construction: Built to withstand high flue gas temperatures and the corrosive environment of high-efficiency combustion cycles.
• Reliable Sequencing: Restores proper pressure switch closure, preventing no-heat calls and ignition lockout cycles.

Common Questions & Troubleshooting:

What are the signs that my Utica 2272156 motor is failing?
Technicians typically identify failure via a seizing motor shaft, a burnt electrical smell from the windings, or a loud rattling noise, often indicating worn internal bearings. If the furnace hums but the 3450 RPM inducer doesn't spin, the motor or its capacitor may be defective.

Does this part include the mounting plate?
Yes, this 2272156 assembly includes the factory-attached metal mounting plate and the required gasket for a complete installation.

Will this resolve a "pressure switch open" fault code?
If the motor is failing to reach its rated RPM or has obstructed blades, it won't create the negative pressure needed to trip the pressure switch. Replacing the inducer assembly is the standard solution for these mechanical draft failures.
