Overview
This OEM blower motor (part #1185447, MTR BLR 1/2 HP 4 SPD) is the direct-drive indoor blower motor for the ICP/Heil/Tempstar WFAR100C048B2 air handler. Rated at 1/2 HP with 4 selectable speeds, it spins the blower wheel that pushes conditioned air through your duct system on every heating and cooling cycle. A failing blower motor is one of the most common reasons a system runs but delivers little or no airflow. Typical failure symptoms include the motor humming but not spinning, overheating and tripping on its internal thermal overload, loud bearing noise, intermittent operation, or no airflow at the registers at all. Because this is the original-equipment motor, the mounting, shaft diameter, rotation, and speed tap wiring match the factory blower assembly exactly.
