Overview
This OEM 1/4 HP condenser fan motor (Part #1177473) drives the outdoor fan on your Tempstar TXH548GKA100 heat pump, pulling air across the coil to reject heat in cooling and absorb it in heating. A failing fan motor causes the system to overheat, trip on high pressure, and lose capacity. Common symptoms are a fan that won't spin, spins slowly or intermittently, hums without starting, or runs hot and cycles off on its internal overload. Bad bearings produce a grinding or squealing noise. Because the condenser cannot shed heat without airflow, a dead fan motor will quickly shut the whole unit down.

Compatibility
Direct OEM fit for the Tempstar TXH548GKA100 heat pump. The 1177473 motor is shared across ICP-family condensing units (Heil, Comfortmaker, Arcoaire) of the same tonnage. Confirm horsepower, rotation, shaft diameter, and mounting before installing, and reuse the correct run capacitor.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter (the capacitor can hold a charge — discharge it safely).
- Access — Remove the fan grille/top panel to reach the motor.
- Document — Photograph the wiring and the fan blade position on the shaft.
- Remove — Disconnect the motor leads, loosen the blade set screw, pull the blade, and unbolt the old motor from the bracket.
- Install — Mount the new motor, transfer the blade to the same shaft depth, and reconnect leads per your photo (wire the run capacitor correctly).
- Test — Restore power and confirm the fan spins up to full speed in the correct direction with no wobble or noise.
Signs You Need a Replacement
