Overview
This is a genuine OEM condenser fan motor (part number 1184599) for the Tempstar TCA748GKA100 air conditioning condensing unit. Rated at 1/4 HP and 825 RPM, this motor drives the outdoor fan that pulls ambient air across the condenser coil to reject heat from the refrigerant. When the condenser fan motor fails, the system can no longer shed heat, leading to high head pressures, compressor overheating, repeated high-pressure lockouts, and a unit that stops cooling. Typical failure signs include a fan that hums but won't spin, a motor that overheats and cycles on its internal overload, noisy worn bearings, or a fan that quits while the compressor keeps running.

Compatibility
Engineered as a direct-fit replacement for the Tempstar TCA748GKA100 condensing unit. This motor is also used across many ICP-family outdoor units (Tempstar, Heil, Comfortmaker, Arcoaire) that share the same 1/4 HP 825 RPM condenser fan platform. Confirm the part number on your existing motor's nameplate and match rotation, shaft size, and capacitor rating before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the top grille/fan assembly screws and lift the fan deck clear of the cabinet.
- Document — Photograph all motor and capacitor wire connections before disconnecting anything.
- Remove — Loosen the fan blade set screw, pull the blade, then unbolt the old motor from the bracket and disconnect its leads.
- Install — Mount the new motor, reinstall the fan blade at the correct depth, and reconnect the leads and run capacitor exactly per your photo.
- Test — Restore power, confirm the fan spins freely in the correct direction, and verify head pressure normalizes during operation.
Signs You Need a Replacement
- Fan hums but will not start, or spins slowly and stalls.
- Motor runs hot and trips on its thermal overload.
- Loud grinding, screeching, or rattling bearing noise.
- High head pressure and compressor lockouts because the coil is not being cooled.
