Overview
This OEM ICP 1/3 HP blower motor module (part number 1190331, pairs with blower motor 1185023) drives the indoor blower wheel on the WAHT304B1 air handler, circulating conditioned air through your duct system. Rated at 1/3 horsepower on 230V, it provides the airflow your system needs for proper heating and cooling capacity. A failing blower motor shows up as weak or no airflow at the registers, loud humming or grinding, intermittent operation as the motor overheats and trips on thermal overload, or a motor that won't start at all. Restoring proper airflow with the correct OEM 1/3 HP motor protects the rest of the system from overheating and short-cycling.

Compatibility
Direct OEM replacement for the ICP / Tempstar / Heil WAHT304B1 air handler and equivalent Comfortmaker fan coil units. Part 1190331 is the complete motor module; 1185023 is the matching blower motor for the same chassis. Confirm horsepower (1/3 HP), voltage (230V), and shaft/mounting configuration against your existing motor before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before touching the motor.
- Access — Remove the air handler service panel and slide out the blower assembly.
- Document — Photograph all motor wiring, the capacitor connections, and the blower wheel position on the shaft.
- Remove — Loosen the wheel set screw, pull the wheel, disconnect the wiring, and unbolt the old motor from the housing.
- Install — Mount the new motor, reinstall the blower wheel at the documented depth, tighten the set screw on the shaft flat, and reconnect wiring per your photo.
- Test — Restore power and verify the blower spins up quietly and moves strong airflow at the registers.
