Overview

This is the OEM ICP 1/2 HP ECM blower motor (part number 1185157) used as the indoor blower in ICP, Heil, and Tempstar air handlers. As an electronically commutated motor, it delivers efficient, quieter, soft-start airflow and modulates to maintain consistent air delivery across the system. A failing ECM blower motor commonly presents as no blower operation, a motor that hums but will not spin, intermittent or surging airflow, or a system that runs without ever satisfying the thermostat because air is not moving across the indoor coil.

My AC fan isn’t spinning. What part do I need?

Fan not spinning, spinning slowly, or making grinding/squealing noises = motor failure. Grinding = bearings failed. Squealing = bearings dry. No spin + hum = check the motor capacitor first before replacing the entire motor.

Is this fan motor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP fan motor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
