What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model T4H461GKD100 — OEM 1177473 | 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 T4H461GKD100 — OEM 1177473 | 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 genuine Tempstar 1/4 HP condenser fan motor (OEM #1177473) drives the outdoor fan on your T4H461GKD100 heat pump, pulling air across the outdoor coil to reject heat in cooling and absorb it in heating. A failing fan motor is one of the most common causes of an overheating compressor and high-pressure trips: when the motor seizes, runs hot, or spins slowly on worn bearings, the coil can't transfer heat and the whole system suffers. This OEM-spec replacement matches the original horsepower, RPM, rotation, and shaft dimensions, so it bolts in and runs at the airflow your unit was designed for.
