What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model TXH537GKA100 — Direct Drive | 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 TXH537GKA100 — Direct Drive | 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 the genuine OEM Tempstar condenser fan motor, part number 1177593, rated at 1/5 HP, for the TXH537GKA100 heat pump. The condenser fan motor spins the outdoor fan blade that pulls air across the coil, rejecting heat in cooling mode and absorbing it in heating mode. A healthy fan motor is essential for proper refrigerant heat exchange — when it weakens or seizes, head pressure climbs, the compressor overheats, and the system loses capacity or trips on high-pressure or thermal overload. This 1/5 HP motor is the exact factory-spec replacement, matched to the original RPM, rotation, shaft, and mounting for a clean swap.

Access — Remove the top grille/fan-shroud screws to lift out the fan assembly.
Document — Photograph the motor wiring, capacitor leads, and fan-blade position on the shaft.
Remove — Loosen the blade set screw, pull the blade, then unbolt the old motor from the bracket.
Install — Mount the new motor, reinstall the blade at the same shaft depth, and wire to the run capacitor per your photos.
Test — Restore power and confirm the fan spins the correct direction at full speed with no wobble or noise.
