ICP 1/2 HP Blower Motor for WPG4244040LKB1 — OEM Furnace Fan Motor | Ships Today

Overview

This OEM 1/2 HP blower motor is the direct-fit indoor fan motor for the ICP / Heil / Tempstar / Comfortmaker WPG4244040LKB1 furnace. It drives the blower wheel that moves conditioned air through the supply ductwork on both heating and cooling cycles. A failed blower motor is a primary cause of weak airflow, overheating limit trips, and complete no-air conditions. Covered OEM part number: 1188128 (Motor Blower 1/2 HP). Worn bearings, an open winding, or a failed start capacitor will stall the motor and force the furnace into a high-limit lockout. This direct replacement restores rated airflow and protects the heat exchanger from overheating.

Specifications

Compatibility

Built for the WPG4244040LKB1 and used across matching ICP-built furnace platforms sold under the Heil, Tempstar, Comfortmaker, and Arcoaire names. Verify horsepower, voltage, rotation, and shaft size against the failed motor before ordering.

Installation Guide

1. Safety First — Disconnect power at the switch and breaker; verify zero voltage with a multimeter.
2. Access — Remove the blower compartment service panel and slide out the blower assembly.
3. Document — Photograph all motor leads, the capacitor wiring, and the wheel set-screw position.
4. Remove — Loosen the blower wheel set screw, pull the wheel, and unbolt the old motor from the mounting band.
5. Install — Mount the new motor, reinstall the wheel at the same depth, and reconnect leads per your photo.
6. Test — Restore power, run heat and cool cycles, and confirm smooth, quiet operation at full airflow.
