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 genuine OEM single-pole 30 amp contactor with shunt (part number 1172472) for the Tempstar T4H348GKD200 heat pump. The contactor is the high-voltage switch that the 24V control circuit uses to start and stop the compressor and outdoor fan. When the thermostat calls, the 24V coil pulls the contacts closed and sends line voltage to the condenser. The built-in shunt provides the second-leg path for this 1-pole design. Contactor contacts pit, burn, and weld over thousands of cycles — a failing contactor causes a buzzing or chattering unit, an outdoor unit that will not start, or one that will not shut off because the contacts have welded closed. It is one of the most common and least expensive condenser failures.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the control panel cover on the condenser.
Document — Photograph every line, load, and 24V coil wire before disconnecting.
Remove — Move each wire one at a time to the new contactor, or label and remove all leads, then unbolt the old contactor.
Install — Mount the new contactor and land each wire on the matching terminal exactly as photographed.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly without chatter and the compressor and fan start.
