Direct Replacement & Compatibility

The HC37MA135 is the factory-authorized direct successor for an extensive lineage of older motor designs. Because this motor is used in vintage furnace applications, the manufacturer part number has been updated many times over the decades. Selecting a Factory Original part guarantees that the physical frame size, motor shaft dimensions, and electrical mounting specifications align precisely with your existing assembly—saving you the complex field modifications or wiring hazards common with universal aftermarket motors.

Why Choose Genuine Carrier OEM?

Older heating systems depend on precise motor compliance to maintain safe heat exchanger temperatures. Substandard universal replacements often pull a different amperage or lack the exact physical torque curve, which can cause the motor to run excessively hot, trip your furnace's high-limit switch, or fail prematurely under continuous load. This Genuine Carrier motor is engineered for strict thermal safety, low vibration, and quiet performance, keeping your classic equipment running safely and efficiently.

Shipping Information

  • Service Area: Shipping rates apply to the continental United States only.

Pro-Tech Installation & Wiring Tip: When upgrading a legacy furnace motor, careful wiring verification is essential.

  • Speed Taps: This motor features 4 distinct speed taps to accommodate varying heating, cooling, or continuous fan settings. Always reference your furnace schematic to map the new leads correctly. Any speed leads not utilized by your system control board must be individually capped with wire nuts or parked on dead terminals to prevent electrical short circuits.
  • Capacitor Maintenance: Check the data plate on the new motor to identify its specific run capacitor microfarad (µF) rating requirement. Always install a brand-new, matching run capacitor when replacing the motor to ensure adequate starting torque and prevent the new windings from overheating.
  • Clearance Check: Secure the motor firmly within its mounting bracket and verify the blower wheel set screw is tightened securely onto the flat part of the motor shaft. Spin the assembly by hand to check for smooth clearance within the blower housing before restoring power to the unit.
