Overview
This is the genuine OEM ECM X-13 motor control module (part number 1185840) for the ICP Tempstar Heil WJH330000K000A2 air handler/heat pump. The X-13 is a constant-torque electronically commutated motor (ECM) rated at 1/3 HP, used to drive the indoor blower. The motor control is the electronic module bolted to the end of the motor that converts the incoming power and 24V taps into the commutated drive signals that spin the rotor at the selected torque profile. ECM blower motors run far more efficiently than older PSC motors, but their control modules are sensitive to power surges, moisture, and overheating — and the module is the component that most often fails first.

Compatibility
Direct-fit replacement for the ICP Tempstar Heil WJH330000K000A2 and related WJH-series units using a 1/3 HP ECM X-13 blower motor control. The X-13 module must match the motor it mounts to — confirm part number 1185840 and the 1/3 HP rating against your existing motor before ordering.
Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter; wait several minutes for the module to discharge.
- Access — Remove the blower compartment panel and slide out the blower assembly if needed.
- Document — Photograph the high-voltage plug and the 24V tap connections before disconnecting.
- Remove — Unplug both connectors, remove the bolts securing the control to the motor, and separate the module.
- Install — Attach the new control to the motor end-shield, then plug in the power and 24V tap connectors exactly per your photo.
- Test — Restore power, call for blower operation, and verify the motor ramps to the correct speed on each tap.

- Blower won't start, or hums and jogs without spinning up
