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 a genuine OEM 4-pole definite-purpose contactor (part number 51307868500) for the Tempstar TDLS1215C. The contactor is the electromechanical switch that energizes the condenser fan motor and compressor circuit whenever the thermostat calls for cooling. When the 115V coil is energized, the four sets of contacts close and pass line voltage to the load; when the call ends, the coil de-energizes and the contacts open. Rated at 20A per pole with a 115V coil, this contactor handles the inrush and running loads of the unit's outdoor section. Common failure symptoms include a unit that hums but won't start, contacts that chatter or buzz, pitted or welded contacts that keep the system running after the thermostat is satisfied, or no outdoor operation at all.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condenser unit's electrical access panel.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note line, load, and coil (115V) wire positions, then transfer wires one at a time and unscrew the old contactor from its mounting rail.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the coil leads land on the 115V coil terminals.
Test — Restore power, call for cooling, and verify the contacts pull in cleanly and the outdoor fan and compressor start.
