Overview
This is the OEM ECM X-13 1/2 HP blower motor control (part #1185845) for the ICP / Heil / Tempstar WJH336000K000A2 packaged heat pump. The X-13 is a constant-torque electronically commutated motor control that drives the indoor blower, holding a programmed torque across changing static pressure for steadier airflow and lower energy use than a PSC motor. The control module is the electronics package that reads the 24V tap signals and commutates the motor windings. When it fails, the blower may not start, run at the wrong speed, or cut out intermittently — leaving you with no airflow, weak airflow, or comfort and temperature-rise complaints.

Installation Guide
- Safety First — Disconnect power and verify zero voltage with a multimeter; ECM capacitors can hold a charge.
- Access — Remove the blower-compartment service panel and slide out the blower assembly if needed.
- Document — Photograph the high-voltage plug and the 24V tap connections.
- Remove — Unplug the connectors, remove the retaining bolts, and separate the control from the motor.
- Install — Seat the new control on the motor, torque the fasteners, and reconnect both plugs per your photo.
- Test — Restore power and confirm the blower ramps and runs at the correct programmed taps.
Signs You Need a Replacement
