Overview
This is a genuine OEM ICP ECM X-13 motor control module (part number 1185284), a 1/2 HP variable-efficiency blower motor used in the WAHT424A2 air handler. The X-13 is a constant-torque ECM that delivers quiet, energy-efficient airflow across multiple tap settings while drawing far less power than a legacy PSC motor. When this motor fails you will typically see no blower operation, intermittent starting, loud buzzing or humming at startup, or weak/uneven airflow at the registers. Because the control electronics are integrated into the motor end-bell, a failed module almost always requires full motor-control replacement rather than a capacitor swap.

Compatibility
Engineered as a direct OEM fit for the ICP/Tempstar/Heil WAHT424A2 fan coil air handler. Always confirm the part number stamped on your existing motor before ordering, as ICP uses several X-13 horsepower ratings across the WAHT product line.
Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage at the motor leads with a multimeter.
- Access — Remove the air handler blower-compartment service panel.
- Document — Photograph the line-voltage, tap/control plug, and ground connections before disconnecting.
- Remove — Unplug the 5-pin control harness, release the blower-housing mounting bolts, slide out the assembly, and transfer the blower wheel and mounting band to the new motor.
- Install — Mount the new X-13 motor, reseat the blower wheel, reinstall in the housing, and reconnect line voltage and the control plug per your photos.
- Test — Restore power, call for fan/heat/cool, and verify smooth ramp-up and proper airflow.
Signs You Need a Replacement
- Blower will not start or starts intermittently.
- Loud humming, buzzing, or grinding at startup.
