My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Is this contactor 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 OEM single-pole contactor (part number 1172472) for the Tempstar T4A348GKA200 condensing unit. Rated at 30 amps with a 24V control coil and an integrated shunt, the contactor is the electrical switch that energizes the compressor and outdoor fan when the thermostat calls for cooling. When the 24V coil pulls in, the main contacts close and line voltage flows to the compressor. Contactors are among the most common failure points in outdoor units because the contacts pit and burn over thousands of switching cycles, and ants or debris can jam the plunger.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter.
Access — Remove the electrical access panel on the condensing unit.
Document — Photograph every wire on the contactor terminals before disconnecting anything.

Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with no chatter or buzzing.
