What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model T4A442GKD100 — 1/5 HP | 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 T4A442GKD100 — 1/5 HP | 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 OEM condenser fan motor (part number 1177593) is the 1/5 HP outdoor fan motor for the Tempstar T4A442GKD100 condensing unit. It spins the condenser fan blade that pulls air across the outdoor coil to reject heat during the cooling cycle. Without adequate airflow, head pressure climbs, the compressor overheats, and the system loses capacity or trips on overload. This motor is the direct OEM replacement, sized at 1/5 HP and built for the continuous outdoor duty cycle of a residential AC condenser.
