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 genuine OEM 1-pole 30-amp definite-purpose contactor (part number 1172472, with shunt) is the main switching relay for the Tempstar T4H330GKE100 heat pump. The contactor uses a 24V control coil to pull in a high-current set of contacts that energize the compressor and condenser fan whenever the thermostat calls for heating or cooling. Rated at 30 amps with a single pole and an integrated shunt, it handles the line-voltage load while the low-voltage 24V coil does the switching. A failed contactor is one of the most common no-start faults: pitted or welded contacts cause chattering, buzzing, or a unit that will not start or will not shut off, while an open or burned 24V coil prevents the contactor from pulling in at all. Replacing it with this OEM contactor restores clean, reliable compressor switching.
