Carrier Blower Motor HD44MQ135 (Replaces HD44MQ128)

Carrier / Bryant / Payne HD44MQ135 Blower Motor | 1/2 HP ECM OEM

The Carrier HD44MQ135 is a genuine factory-authorized Electronically Commutated Motor (ECM). As an Original Equipment Manufacturer (OEM) component, it is designed specifically for Carrier and Bryant high-efficiency furnaces and air handlers to provide precision variable-speed airflow.

This 1/2 HP motor utilizes advanced variable-speed technology, allowing it to modulate its output based on the real-time demands of your HVAC system. Unlike standard fixed-speed motors, this ECM can ramp up or down to maintain optimal comfort, improve dehumidification, and significantly reduce energy consumption. Using this genuine Factory Authorized Part ensures the motor's internal programming and communication protocols are perfectly matched to your unit's control board.

Compatibility & Cross-Reference

The HD44MQ135 is the manufacturer-designated current standard and serves as the direct service replacement for several legacy and production models:

• Directly Replaces Part Number: HD44MQ128.
• Technology Type: High-efficiency Variable Speed ECM.
• Equipment Fitment: Primarily used in Carrier Infinity and Bryant Evolution series gas furnaces and fan coil units.

Technical Specifications

Why Choose a Genuine Carrier OEM ECM Motor?

• Optimized Comfort: Variable-speed operation allows for lower-speed continuous fan modes, which improves air filtration and prevents the "blast" of cold air common with single-speed systems.
• Intelligent Airflow: The motor automatically adjusts its torque to maintain the programmed CFM (Cubic Feet per Minute), even as static pressure increases due to a dirty air filter or complex ductwork.
• Quiet Operation: Features soft-start and soft-stop ramp profiles, which eliminate the abrupt noise associated with motors turning on and off at full power.
• Precision Programming: Comes pre-loaded with the specific airflow logic required for your Carrier/Bryant equipment, ensuring the heat exchanger does not overheat and the evaporator coil does not freeze.
