Tempstar 1/5 HP Condenser Fan Motor for T4H448GKD100 — OEM #1177593 | Ships Today

Overview

This OEM 1/5 HP condenser fan motor (part #1177593) drives the outdoor fan on your Tempstar T4H448GKD100, pulling air across the condenser coil to reject heat. When the motor fails the coil can't dissipate heat, causing high head pressure, compressor overheating, and eventual lockout. Typical failure symptoms include a fan that won't start, hums but doesn't spin, runs hot and cycles on its thermal overload, spins slowly, or makes loud bearing noise. A failed run capacitor often kills these motors, so replace the matching capacitor at the same time.

Specifications

Compatibility

Direct OEM fit for the Tempstar T4H448GKD100 and other ICP-family (Heil, Comfortmaker, Tempstar) condensing units originally equipped with motor #1177593. Verify shaft size, rotation, and capacitor rating against your old motor before installing.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter.
2. Access — Remove the top grille/fan assembly screws to lift out the fan and motor.
3. Document — Photograph the wire colors, capacitor terminals, and blade position on the shaft.
4. Remove — Loosen the blade set screw, pull the blade, unbolt the old motor from the bracket, and disconnect leads.
5. Install — Mount the new motor, transfer the fan blade to the same depth, and wire per your photo.
6. Test — Restore power and confirm the fan spins up to full speed in the correct rotation.

Signs You Need a Replacement

• Fan won't start or only hums
• Motor runs hot and trips on thermal overload
• Loud grinding or squealing bearings
