Overview
These OEM replacement motors keep air moving through your ICP WPA4424000RKB1 system. The 1/2 HP blower motor (part number 1188130) drives the indoor air handler to circulate conditioned air through the ductwork, while the 1/5 HP condenser fan motor (part number 1186359) pulls air across the outdoor coil to reject heat. A failing motor shows up as weak airflow, no airflow, overheating and thermal cutout, or a unit that draws excess amperage. Worn bearings produce grinding or squealing, and a seized motor will trip the breaker or burn out the run capacitor. Replacing a motor at the first sign of trouble protects the compressor and the rest of the system from heat-related damage.

Compatibility
Direct-fit OEM motors for the ICP/Heil/Tempstar/Comfortmaker WPA4424000RKB1 and units sharing the same blower and condenser fan assemblies. Verify HP, RPM, rotation, voltage, and shaft diameter against your original motor before installing.
Installation Guide
- Safety First — Disconnect power and verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the service panel (condenser top grille for the fan motor, blower compartment door for the blower).
- Document — Photograph all wiring and note capacitor connections and blade/wheel position on the shaft.
- Remove — Disconnect leads, remove the fan blade or blower wheel, and unbolt the motor from its mount.
- Install — Mount the new motor, transfer the blade/wheel to the same shaft depth, and reconnect wiring per your photo.
- Test — Restore power and confirm smooth startup, correct rotation, and full airflow.
Signs You Need a Replacement
- Weak airflow or no airflow from supply registers or the outdoor fan.
- Grinding, squealing, or humming from a motor that won't spin.
- Motor runs hot and trips on thermal overload, then restarts later.
- Repeated run-capacitor failures or breaker trips on startup.
