What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model TXH542GKA100 — OEM 1177593 | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 OEM 1/5 HP condenser fan motor (part number 1177593) for the Tempstar TXH542GKA100 heat pump/condensing unit. The condenser fan motor turns the outdoor blade that moves air across the outdoor coil, rejecting heat in cooling and absorbing it in heating. As the motor's bearings wear or windings degrade, the unit develops high head pressure, short cycles on the high-pressure switch, and delivers warm air indoors. This 1/5 HP direct-drive motor matches the original blade, shroud, and amp draw for correct airflow and reliable operation.
