What HP motor do I need for my Tempstar unit?

The correct replacement for Tempstar model T9MPV050F12C1 — 1/2 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 T9MPV050F12C1 — 1/2 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 OEM 1/2 HP variable-speed blower motor kit (part #1175643) drives the circulating air through your Tempstar T9MPV050F12C1 gas furnace. As a variable-speed (ECM) motor, it ramps airflow up and down for quiet operation, better humidity control, and improved efficiency compared with a standard PSC motor. The kit includes the motor for a complete blower replacement. A failing variable-speed motor may run intermittently, fail to start, produce reduced or no airflow, overheat and cut out on thermal limit, or trigger blower-fault codes at the control board. Restoring proper airflow protects the heat exchanger from overheating and keeps the system delivering rated capacity.
