What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model T4A448GKD100 — 1/4 HP OEM | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number T4A448GKD100 — 1/4 HP OEM | Ships Today.

My AC fan is not spinning. What part do I need?

A fan that does not spin, spins slowly, or makes grinding or squealing noises needs a new motor. Grinding means the bearings have failed. Squealing means the bearings are dry. No spin with a humming sound means the capacitor may be the issue. Check the motor capacitor before replacing the entire motor.

Is this fan motor compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This is a genuine OEM 1/4 HP condenser fan motor (part #1177473) for the Tempstar T4A448GKD100 air conditioning condensing unit. The condenser fan motor drives the outdoor fan blade that pulls air across the condenser coil, rejecting heat from the refrigerant so the system can cool effectively. A 1/4 HP rating provides the airflow this 4-ton class condenser requires. When the fan motor fails, the unit loses its ability to shed heat, leading to high head pressure, compressor overheating, and eventual compressor shutdown or damage. Common failure signs include a fan that won't spin, a fan that hums but doesn't start, grinding bearing noise, or a motor that runs hot and trips on thermal overload.

Compatibility

This OEM fan motor is a direct-fit replacement for the Tempstar T4A448GKD100 condensing unit and matches the 1/4 HP condenser fan motor used across comparable ICP family outdoor units (Heil, Comfortmaker, and related models). Verify your existing motor's horsepower, rotation, and mounting before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter before servicing.
Access — Remove the top grille/fan assembly screws to lift the fan and motor out of the unit.
Document — Photograph the wiring, capacitor leads, and fan blade position/spacing before disconnecting.
Remove — Disconnect the motor leads, remove the fan blade set screw, and unbolt the old motor from the mount.
Install — Mount the new motor, transfer the fan blade to the correct depth, and reconnect the leads (including the run capacitor) per your photos.
Test — Restore power and call for cooling; confirm the fan spins up to full speed in the correct direction and runs quietly.
