ICP ECM Blower Motor for WAHM364B1 — 1/2 HP | Ships Today

Overview

This OEM 1/2 HP ECM blower motor (part number 1185157) drives the indoor blower wheel in your ICP WAHM364B1 air handler. As an electronically commutated motor, it delivers high efficiency, quiet operation, and steady airflow even as duct static changes — a meaningful upgrade in comfort and energy use over a standard PSC motor. When it fails you'll notice no airflow on a call for heat or cool, intermittent or hard starting, loud bearing noise, or a motor that overheats and shuts down on its internal protection. Worn bearings, a failed motor module, and power surges are the most common culprits.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before servicing.
2. Access — Remove the air handler blower-compartment service panel.
3. Document — Photograph the motor wiring, plug, and blower-wheel position on the shaft before disconnecting.
4. Remove — Unplug the motor harness, loosen the blower-wheel setscrew, pull the wheel, then unbolt the motor from the housing.
5. Install — Slide the new motor in, reinstall the blower wheel at the same shaft depth, torque the setscrew, and reconnect the harness per your photo.
6. Test — Restore power and verify smooth, quiet blower operation on each speed.
