Reznor 1005553 Motor

The Reznor 1005553 is a critical OEM replacement motor designed specifically for the venter assembly in 75,000 BTU gas-fired unit heaters. This high-performance C-frame venter motor operates at 115V, drawing 24W (approximately 0.03 HP) at a consistent 2950 RPM to ensure precise induced draft combustion. Engineered by Nortek, the 1005553 is the direct replacement for Reznor 260422, providing a drop-in solution for service technicians working on UBX75, UBZ75, UDX75, and UDZ75 models. The motor plays a vital role in venter motor replacement procedures by maintaining the proper air-to-fuel ratio, preventing soot buildup, and ensuring exhaust gases are safely purged from the heat exchanger. Its compact, shaded-pole design is built for the high-cycle demands of industrial and commercial heating environments, ensuring the exhaust venter motor operates with the reliability required for harsh rooftop or warehouse conditions.

Common Questions

Is the Reznor 1005553 compatible with older 260422 motors?
Yes, the 1005553 is the official supersede for the discontinued 260422. It matches the original mounting footprint and electrical specifications for a seamless transition.

Which unit heater models use this specific venter motor?
This motor is the primary component for the venter assembly in Reznor’s 75,000 BTU units, including the UDX75, UDZ75, UBX75, and UBZ75 series.

What are the signs that a venter motor needs replacement?
Technicians should look for inducer pressure switch errors, excessive vibration at startup, or a total failure of the motor to reach 2950 RPM, which prevents the ignition sequence.
