Overview
This genuine OEM ECM X-13 fan motor control (OEM #1185843) is the 1/2 HP variable-speed blower motor assembly for the ICP/Tempstar/Heil WPG3304060LKC1 package gas unit. The X-13 is a constant-torque ECM motor that maintains programmed airflow across changing static pressure, delivering quieter operation and better energy efficiency than a standard PSC motor. When this motor fails you'll typically see no blower operation, intermittent starting, error codes at the control board, or the furnace locking out on high limit because air is not moving across the heat exchanger. Replacing it with the exact OEM motor preserves the factory airflow programming and avoids the trial-and-error of a universal swap.

Installation Guide
- Safety First — Disconnect power at the unit disconnect and verify zero voltage with a multimeter before touching wiring.
- Access — Remove the blower compartment service panel.
- Document — Photograph all motor and control wiring, plus the blower wheel set-screw position on the shaft.
- Remove — Loosen the wheel set screw, slide the blower assembly out, then unbolt the old motor and transfer the wheel to the new motor at the same depth.
- Install — Mount the new ECM X-13, reinstall the blower assembly, and reconnect all wiring per your photos.
- Test — Restore power and confirm the blower ramps and runs on each speed tap.
Signs You Need a Replacement
- Blower will not start or runs intermittently
