Overview
This genuine OEM condenser fan motor (part number 1186359) is the factory replacement for the ICP / Tempstar / Heil WPH4484000RKB1 heat pump. Rated at 1/5 HP and 810 RPM, it drives the outdoor fan blade that pulls air across the condenser coil to reject heat during cooling and absorb it during heat-pump heating. A failed condenser fan motor causes the outdoor unit to overheat, trip on high pressure, and lose capacity — often the system runs but won't cool, or shuts down minutes after starting. Replacing a worn motor restores proper airflow, protects the compressor from heat-related failure, and brings the system back to rated performance.

Compatibility
Built as the direct replacement for the ICP WPH4484000RKB1 heat pump condensing unit. Because ICP supplies multiple brands, this motor also fits equivalent Tempstar, Heil, Comfortmaker, and Arcoaire outdoor units originally equipped with part 1186359. Verify horsepower, speed, rotation, and shaft size against your existing motor before installing. A matching run capacitor should be inspected and replaced if the motor failed under load.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching wiring.
- Access — Remove the top grille and fan assembly screws to lift the fan blade and motor out of the cabinet.
- Document — Photograph the capacitor wiring and motor lead colors before disconnecting.
- Remove — Loosen the blade set screw, transfer the blade to the new motor at the same depth, then unbolt the old motor from the bracket.
- Install — Mount the new motor, reinstall the blade, and reconnect the leads and capacitor per your photo.
- Test — Restore power, call for cooling, and confirm the fan spins up to full speed in the correct direction.
Signs You Need a Replacement
- Outdoor fan won't start, or spins slowly and struggles.
- System trips on high-pressure or short-cycles in hot weather.
- Motor is hot to the touch, smells burnt, or makes grinding bearing noise.
- Fan blade turns freely by hand but won't run on a cooling call.
