Overview
This genuine OEM 1/3 HP, 3-speed blower motor (ICP part number 1185856, "MOTOR BLOWER 1/3 HP 3 SPD") drives the indoor blower wheel on the ICP / Heil / Tempstar WFML090B042B3 gas furnace. It circulates conditioned air through the supply ductwork during both heating and cooling, with three selectable speed taps so the airflow can be matched to heat and AC demand. When a blower motor fails — from worn bearings, an open winding, or a tripped thermal overload — the furnace may produce heat but move little or no air, overheat and short-cycle on the limit switch, or run noisily. Replacing it with the correct OEM motor restores rated airflow and protects the heat exchanger from overheating.

Compatibility
Built for the ICP/Heil/Tempstar WFML090B042B3 furnace and other WFML-series / ICP-family units specifying this 1/3 HP 3-speed blower motor. Confirm shaft diameter, rotation, mounting, and the run-capacitor rating match your existing motor before installing.
Installation Guide
- Safety First – Disconnect power at the furnace switch and breaker, then verify zero voltage and discharge the run capacitor with a multimeter.
- Access – Remove the blower-compartment service panel and slide out the blower assembly.
- Document – Photograph all speed-tap wiring, the capacitor leads, and the blower-wheel position on the shaft.
- Remove – Loosen the wheel set screw, pull the wheel, unbolt the old motor from the mount, and transfer the mount band.
- Install – Bolt the new motor in, set the wheel to the documented depth, and reconnect speed taps and capacitor per your photo.
- Test – Restore power, run heating and cooling calls, and confirm smooth, quiet airflow on the selected speeds.
Signs You Need a Replacement
- Blower hums but will not start, or starts only with a push.
- Loud grinding or squealing bearings.
- Motor overheats and shuts off on thermal overload, causing short-cycling.
- Weak or no airflow at the supply registers during a call.
