ICP Blower Motor Module for WAHM304B1 — 1/3 HP 230V | Ships Today

Overview

This OEM blower motor module (part number 1190331, pairs with blower motor 1185023) is the 1/3 HP, 230V motor that drives airflow through your ICP WAHM304B1 air handler. It spins the blower wheel that pushes conditioned air across the coil and into your ductwork. When the motor fails you'll notice no airflow, weak airflow, or a system that runs without ever satisfying the thermostat — and a seized motor can cause the unit to overheat and trip on its safety limit. Installing the correct OEM module restores rated CFM and keeps the rest of the system operating within spec.
