What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model TXA648GKA100 — 1/4 HP OEM | 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 TXA648GKA100 — 1/4 HP OEM | 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 1/4 HP condenser fan motor (part #1177473) for the Tempstar TXA648GKA100 outdoor unit. The condenser fan motor drives the fan that pulls air across the outdoor coil so the system can reject the heat it removes from the home. When this motor fails, the compressor loses adequate heat rejection, head pressure rises, and the unit overheats and trips its high-pressure or overload protection. Typical failure symptoms include a fan that hums but won't start, a fan that turns slowly, bearing noise or grinding, intermittent operation as the motor overheats, and a condenser that runs hot. Fitting the correct 1/4 HP OEM motor restores proper airflow and protects the compressor from heat-related damage.

Access — Remove the top fan grille/panel screws and lift the fan assembly clear of the cabinet.
Document — Photograph all motor wiring and run-capacitor connections before disconnecting.
Remove — Loosen the fan blade set screw, pull the blade, then unbolt the old motor from the bracket and disconnect its leads.
Install — Mount the new 1/4 HP motor, transfer the fan blade to the same depth, and reconnect leads to the capacitor and contactor per your photo.
Test — Restore power, confirm the fan starts immediately and rotates in the correct direction (drawing air up), and verify normal head pressure.
