ICP ECM X-13 Motor Control for WPH3304000RKC1 — 1/2 HP | Ships Today

Overview

This is the genuine OEM ECM X-13 motor control module (part 1185843), a 1/2 HP electronically commutated blower motor control for the ICP / Tempstar / Heil WPH3304000RKC1 packaged heat pump. The X-13 is a constant-torque ECM that delivers efficient, quiet airflow and holds its programmed torque tap across varying static pressure. When the control fails you'll see a blower that won't start, runs at the wrong speed, surges, or hums without turning. Replacing the module restores correct, energy-efficient air delivery.

3. Document — Photo the line/neutral and the low-voltage tap connections on the control.
4. Remove — Unplug the harnesses and separate the control module from the motor end shield.
5. Install — Mate the new control to the motor, reconnect the power and tap harnesses per your photo.
6. Test — Restore power, run the blower, and confirm correct speed and smooth, quiet operation.
