ICP Blower Motor for WFAR040A030B2 — 1/3 HP | Ships Today

Overview

This is the OEM 1/3 HP blower motor (part number 1185446) for the ICP/Tempstar/Heil WFAR040A030B2 furnace air handler. The blower motor drives the indoor blower wheel that circulates conditioned air through your ductwork on both heating and cooling cycles. Rated at 1/3 horsepower on 115V, this direct-drive PSC motor is the heart of airflow in the system. When a blower motor fails you typically see no airflow at the registers, a humming motor that won't start, intermittent operation, overheating that trips the limit switch, or loud bearing noise. Replacing it with the correct OEM-spec motor restores full rated airflow and protects the rest of the equipment from overheating.
