What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model T4H460GKD300 — 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 T4H460GKD300 — 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 T4H460GKD300 outdoor unit. This direct-drive motor spins the outdoor fan blade that pulls air across the condenser coil to reject heat. A failing fan motor causes high head pressure, compressor overheating and lockout, a unit that hums but won't spin, or a fan that runs hot and cycles on its internal overload. Restoring proper airflow with the correct OEM motor protects the compressor and keeps the system cooling and defrosting as designed.
