Overview
This genuine OEM ECM X-13 motor control module (part number 1185845) is the 1/2 HP constant-torque blower motor controller for the ICP / Heil / Tempstar WJH336000KTP0A1 packaged heat pump. The X-13 is a programmed electronically commutated motor that holds a steady torque across changing static pressure, delivering quieter operation and lower energy draw than a standard PSC blower. The control module is the brain bolted to the motor end bell — it reads the 24V tap signals from the control board and drives the rotor accordingly. When the module fails, the blower may run at the wrong speed, surge, refuse to start, or trip out entirely, even though the motor itself is good. This OEM module restores correct airflow staging.

Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter at the motor leads; ECM capacitors can hold a charge, so wait several minutes.
- Access — Remove the blower-access service panel and slide out the blower assembly if needed.
- Document — Photograph the high-voltage plug, the 24V control plug, and each tap position before disconnecting.
- Remove — Unplug both connectors and unbolt the failed control module from the motor end bell.
- Install — Mount the new OEM module to the motor, reseat both plugs, and match the control taps per your photo.
- Test — Restore power and verify the blower ramps to the correct speed on heat, cool, and fan calls.
Signs You Need a Replacement
- Blower won't start or starts then stalls
- Motor surges, hunts, or runs at the wrong speed
- Weak or inconsistent airflow at the registers
