Overview
This is the genuine OEM 1/2 HP X-13 blower motor (part 1186863) for the ICP / Tempstar / Heil WPG4304040RKA1 package unit. The X-13 is a constant-torque ECM (electronically commutated motor) that drives the indoor blower wheel, moving conditioned air through the duct system on both heating and cooling cycles. Compared to old PSC motors, the X-13 runs more efficiently, holds airflow steady against duct static, and stages off the control board's selected taps. A failing blower motor leads to weak airflow, overheating limit trips in heat mode, frozen coils in cool mode, or a complete no-airflow condition. This OEM motor restores rated CFM and quiet operation.

Compatibility
Built as the factory blower replacement for the ICP WPG4304040RKA1 packaged system and used across comparable ICP, Tempstar, Heil, and Comfortmaker units that specify a 1/2 HP X-13 motor. Confirm shaft diameter, rotation, mounting, and the motor's program/tap configuration match your original before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and unit disconnect, then verify zero voltage with a multimeter.
- Access — Remove the blower-compartment panel and slide out the blower assembly.
- Document — Photograph the motor wiring, tap connections, and blower-wheel position on the shaft.
- Remove — Loosen the wheel set screw, pull the wheel, then unbolt the motor from the housing.
- Install — Mount the new motor, set the blower wheel to the same depth, and reconnect the harness per your photo.
- Test — Restore power, run heat and cool cycles, and confirm strong, steady airflow with no vibration.
Signs You Need a Replacement
- Weak or no airflow from the supply registers.
- Furnace trips on high-limit from low airflow in heat mode.
