Zhongshan Broad-Ocean Y7L623F07 HC45TQ135 Blower Motor | 3/4 HP, 115V, 1075 RPM

Zhongshan Broad-Ocean Y7L623F07 (Carrier HC45TQ135) 3/4 HP 115V 1075 RPM 5-Speed PSC Furnace/Blower Motor, Frame 48Y OAO, reversible leads, capacitor 15 µF/370 VAC, OEM-style replacement for Carrier/Bryant/Payne systems

Condition: New — not used. Packaged in a generic box. Capacitor not included (requires 15 µF, 370 VAC). No mounting hardware or blower wheel included.

Overview

The Zhongshan Broad-Ocean Y7L623F07 (often referenced by Carrier® OEM part HC45TQ135) is a 3/4 HP, 115 VAC, 1075 RPM, 5-speed PSC (permanent split capacitor) blower motor engineered for residential/light-commercial furnace and air handler applications. It’s a direct-fit style replacement for many Carrier/Bryant/Payne units using the HC45TQ-series motors. The motor features a compact 48Y frame with open air over (OAO) enclosure for through-air cooling, multi-speed color-coded leads for easy airflow tuning, and standard belly-band mounting. Use with a 15 µF, 370 VAC run capacitor (not included).

This model closely aligns with Carrier HC45TQ125 (Y7L623F57) and other HC45TQ variants. Always match HP, voltage, RPM, frame, rotation, shaft, and capacitor to your unit’s specification tag before installation.

Key Features

• 3/4 HP, 115V, 60 Hz, single-phase for strong airflow in medium/large furnaces and air handlers
• 1075 RPM, 5 speeds (tap selectable) to balance CFM across heat/cool/fan-only modes
• PSC design for proven reliability and easy service with a simple run capacitor
• Frame 48Y, OAO enclosure; belly-band mount (straps not included)
• Standard 1/2″ shaft (typical 48-frame) with flat; accepts common blower wheels (verify hub size & set-screw alignment)
• Insulation Class B, FLA ≈ 6.5 A (from label data provided) for durable duty
• Leads pre-terminated (typical color code for multi-speed and capacitor circuits; confirm diagram on motor label)
• Rotation: CCWSE/CWLE is typical for Carrier HC45TQ series; verify on nameplate and wiring diagram (reversible via lead swap on many PSC motors)

Motor Specifications (as provided / industry-standard for this build)

• Horsepower (HP): 3/4
• Voltage: 115 VAC
• Frequency: 60 Hz
• Full-Load Amps (FLA): ~6.5 A
• Speed: 1075 RPM (5-speed taps)
• Phase: 1 (single-phase)
• Capacitor: 15 µF, 370 VAC (not included)
• Motor Service Factor (SF): typically 1.00 (verify label)
• Motor Design: PSC, split-phase with run cap
• Enclosure: OAO (Open Air Over)
• Frame: 48Y (belly-band mount)
• Bearings: sleeve (common on OEM PSC; verify label/box)
• Insulation Class: B
• Ambient: up to 40 °C typical
• Shaft & Rotation: 1/2″ dia; CCWSE/CWLE (typical for HC45TQ; confirm on nameplate/wiring)
• Leads: multi-speed (usually Black = High, Yellow/Blue/Red = lower speeds; Brown/Brown-White to capacitor; White = neutral — confirm your diagram)

Rotation note (important): If your original motor label shows the opposite rotation, most PSC blower motors can be reversed by swapping the appropriate aux/start winding leads per the diagram. Always follow the schematic on the actual motor.

Applications / Where It’s Used

• Residential furnaces & air handlers (gas, oil, electric) requiring 3/4 HP, 115V, 1075 RPM PSC blower motors
• Split systems & package units (indoor blower section) for heating and cooling
• Replacement/retrofit when the original motor matches the key ratings (HP/Volts/RPM/Frame/Rotation/Cap value)

Pros

• Broad compatibility with Carrier/Bryant/Payne OEM part streams (HC45TQ series)
• 5-speed flexibility to dial in CFM per mode or static pressure needs
• Reliable PSC topology with readily available capacitors and parts
• OEM-style fit in many belly-band 48-frame housings

Cons

• Run capacitor required (not included)
• PSC efficiency is lower than ECM; if you need variable torque/efficiency, consider an ECM retrofit kit

Installation & System Notes

• Mounting: Uses belly-band strap around the 48-frame body. Re-use your strap or source a 48-frame band.
• Capacitor wiring: Connect 15 µF/370 VAC run cap across the Brown/Brown-White (or per the schematic). Replace old capacitors when replacing motors.
• Airflow/CFM: Use High (Black) for cooling, lower taps for heating as required by your furnace label; verify static pressure and temperature rise post-install.
• Rotation check: Verify fan wheel direction (air should discharge toward the heat exchanger/coil). Reverse motor if airflow is incorrect.
• Safety: Kill power, lockout/tagout, balance blower wheel, and check amp draw vs. nameplate after install.
