ICP Blower Motor for WPG4244040RKB1 — 1/2 HP | Ships Today

Overview

This OEM 1/2 HP blower motor drives the indoor blower wheel that circulates conditioned air through your ICP WPG4244040RKB1 packaged unit during both heating and cooling. The blower motor is one of the hardest-working components in the system, and bearing wear, winding failure, or an overheating motor leads to weak airflow, no airflow, or a motor that runs hot and cycles on its thermal overload. A blower that hums but will not spin, squeals from worn bearings, or shuts down after a few minutes from overheating typically needs replacement. This is part 1188128 (MOTOR BLOWER 1/2 HP). Confirm horsepower, voltage, rotation, shaft diameter, and mounting before installing.

Specifications

Compatibility

Direct OEM replacement for the ICP/Heil/Tempstar WPG4244040RKB1 and other ICP-family units using a 1/2 HP blower motor. Verify HP, voltage, rotation direction, shaft size, and mounting pattern against your existing motor.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter at the motor leads.
2. Access — Remove the blower service panel and slide out the blower assembly if required.
3. Document — Photograph all motor wiring, the run capacitor leads, and the blower wheel position on the shaft.
4. Remove — Loosen the wheel set screw, pull the wheel, then unbolt the old motor from the blower housing.
5. Install — Mount the new motor, reinstall the blower wheel at the same depth, and reconnect wiring and capacitor per your photo.
6. Test — Restore power and confirm correct rotation, full airflow, and quiet operation on a heat and cool call.

Signs You Need a Replacement

• Blower hums but does not spin.
• Squealing or grinding from worn motor bearings.
• Weak or no airflow at the registers.
