Overview
This genuine OEM condenser fan motor (part number 1186359) is the factory replacement for the ICP/Tempstar/Heil WPA4364000RKA1 outdoor condensing unit. Rated at 1/5 HP and 810 RPM, this motor turns the outdoor fan blade that pulls air across the condenser coil to reject the heat your system removes from the home. When a condenser fan motor fails, the compressor loses its ability to shed heat, head pressure climbs, and the unit will short-cycle on the high-pressure switch or overheat and trip — leaving you with warm air indoors and a hot, struggling outdoor unit. Worn bearings, an open winding, or a seized shaft are the usual failure modes.

Compatibility
Built as the direct factory replacement for the ICP WPA4364000RKA1 condensing unit and used across ICP-family outdoor units marketed as Tempstar, Heil, Comfortmaker, and Arcoaire. Verify the printed part number 1186359, the 1/5 HP rating, and the shaft and mounting dimensions against your existing motor before installing. Reuse the matching run capacitor only if it tests within tolerance.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the top fan grille/shroud to reach the motor and blade.
- Document — Photograph all motor and capacitor wiring and note the blade's position on the shaft.
- Remove — Loosen the blade set screw and pull the blade, unbolt the motor from the bracket, and disconnect the leads.
- Install — Mount the new motor, set the blade to the original depth, reconnect leads to the capacitor per your photo, and confirm correct rotation direction.
- Test — Restore power, call for cooling, and verify the fan spins up freely and pulls air upward.
Signs You Need a Replacement

- Unit short-cycles or trips on high head pressure.
