What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model TXA642GKA100 — OEM 1177593 | 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 TXA642GKA100 — OEM 1177593 | 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

The Tempstar 1177593 is the OEM 1/5 HP condenser fan motor for the TXA642GKA100 outdoor unit. This motor drives the condenser fan that pulls air across the outdoor coil to reject heat — without it, head pressure climbs, the compressor overheats, and the system trips on high-pressure or thermal protection. A failing condenser fan motor shows up as a fan that won't spin, hums but won't start, runs hot, or grinds from worn bearings. The genuine 1177593 restores correct airflow, RPM, and cooling capacity.

Compatibility

Built for the Tempstar TXA642GKA100 condensing unit and matching ICP-family (Heil, Comfortmaker) condensers that originally used the 1/5 HP 1177593 motor. Verify horsepower, voltage, rotation, and shaft size against your existing motor before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the top grille/fan assembly screws to lift out the fan and motor.
Document — Photograph all motor wiring, capacitor leads, and fan-blade position on the shaft.
Remove — Loosen the fan-blade set screw, pull the blade, then unbolt the old motor from the bracket.
Install — Mount the new 1177593, transfer the fan blade at the same depth, and wire it per your photo (and to the run capacitor).
Test — Restore power, confirm the fan spins the correct direction at full speed, and check amp draw.

Signs You Need a Replacement
