ICP ECM X-13 Blower Motor Control 1/2 HP for WPA3304000RKC1 — OEM 1185843 | Ships Today

Overview

This is the OEM 1/2 HP ECM X-13 motor control (part number 1185843) for the ICP / Tempstar / Heil WPA3304000RKC1 unit. The X-13 is a constant-torque electronically commutated motor that drives the indoor blower at programmed speed taps, delivering quiet operation and far better efficiency than a standard PSC motor. When this motor fails, the blower may not run, may run at the wrong speed, or may start and stop intermittently — leaving the system with weak airflow, poor heating/cooling, or nuisance lockouts. This factory replacement restores correct, efficient airflow across all speed settings.

Compatibility

Factory replacement blower motor control for the ICP / Tempstar / Heil WPA3304000RKC1 unit. Confirm horsepower (1/2 HP) and the X-13 motor type against your existing motor before installing.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter before servicing.
2. Access — Remove the blower service panel and slide out the blower assembly if needed.
3. Document — Photograph the high-voltage harness, the 24V speed-tap connector, and the blower wheel position on the shaft.
4. Remove — Disconnect the harnesses, loosen the wheel set screw, and unbolt the old motor from the housing.
5. Install — Mount the new motor, set the blower wheel to the same position, and reconnect both harnesses per your photo.
6. Test — Restore power and confirm the blower ramps to the correct speed on heating and cooling calls.

Signs You Need a Replacement

• Blower does not run despite a valid call and good control signal
• Weak or inconsistent airflow at the registers
