ICP 1/2 HP ECM Blower Motor for SUP18E230V1IA — B0381106 | Ships Today

Overview

This is the genuine ICP/Tempstar/Heil 1/2 HP ECM motor (OEM part B0381106) for the SUP18E230V1IA. ECM (electronically commutated motor) technology delivers variable, programmable speed control for quieter operation, steadier airflow, and significantly higher efficiency than a standard PSC motor. The motor drives the system's blower to move conditioned air across the coil and through the ductwork. A failing ECM motor may run hot, surge or hunt for speed, stop and restart, throw module faults, or quit entirely — leaving you with weak airflow or no airflow at all. Installing the correct 1/2 HP OEM ECM motor restores factory-rated CFM and efficiency.

3. Document — Photograph the motor harness, module connections, and blower wheel position.
4. Remove — Disconnect the harness, loosen the wheel set screw, and unbolt the old motor from the housing.
5. Install — Mount the new ECM motor, reseat the blower wheel at the same depth, and reconnect the module harness per your photos.
6. Test — Restore power and verify the motor ramps smoothly to commanded speed with proper airflow.

Signs You Need a Replacement
