Overview
This genuine OEM X-13 ECM motor control module (part number 1185840) is the 1/3 HP electronically commutated blower motor used in the ICP / Tempstar / Heil WJA330000KTP0B1 system. The X-13 ECM is a constant-torque, multi-tap motor that delivers higher efficiency, quieter operation, and better airflow consistency than a standard PSC motor. The integrated control selects the programmed speed tap based on the low-voltage signal it receives from the furnace or air handler control board. When this motor fails you will typically notice no blower airflow, intermittent or surging airflow, the motor cycling on thermal overload, error codes at the control board, or a humming motor that will not spin up. Because the control electronics are built onto the motor, replacing the assembly restores both the drive and the speed logic.

Compatibility
Fits the ICP, Tempstar, Heil, Comfortmaker, and Arcoaire WJA330000KTP0B1 unit and other ICP-family blower assemblies that specify a 1/3 HP X-13 ECM motor. Confirm the horsepower, shaft size, rotation, and motor mount match your existing X-13 motor before installation, and verify the speed taps are wired to the correct terminals.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter before servicing.
- Access — Remove the blower compartment service panel.
- Document — Photograph the line-voltage and 24V control connections and the speed-tap positions before disconnecting.
- Remove — Disconnect the harness, loosen the blower wheel set screw, pull the wheel, and unbolt the old motor from the housing.
- Install — Mount the new X-13 motor, reinstall the blower wheel and set screw, and reconnect the harness exactly per your photo.
- Test — Restore power, run a heating and cooling cycle, and confirm smooth, correct-speed airflow.
Signs You Need a Replacement
- No blower airflow despite a call for heat or cool
