Overview
This is a genuine OEM 1/3 HP, 230V blower motor module (OEM part numbers 1190331 and 1185023) for the ICP/Tempstar/Heil WAPL304A3 air handler. The blower motor is the heart of your air distribution system — it spins the indoor blower wheel to move conditioned air through your ductwork. As an ECM-style motor module, it delivers efficient, variable airflow for both heating and cooling modes. When this motor fails you will typically notice weak or no airflow at the registers, the system running but no air moving, unusual humming or grinding noises, the motor overheating and tripping on thermal overload, or the blower failing to start at all. Replacing it with the correct OEM module restores rated airflow and protects the rest of your system from strain.

- Test — Restore power and verify the blower starts, ramps, and moves air at the registers in both heat and cool modes.
