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.

Overview

This OEM Tempstar 1/12 HP Condenser Fan Motor (part number 1177856) drives the outdoor fan that pulls air across the condenser coil to reject heat from your T4A318GKD200 system. When this motor fails, the unit loses its ability to shed heat — leading to high head pressure, warm air indoors, compressor overheating, and protection trips. Symptoms include a fan that won't spin, hums but won't start, runs slow, or makes loud bearing noise. Installing the correct OEM 1/12 HP motor restores proper airflow, head pressure, and cooling capacity.
