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 OEM 40-amp definite purpose contactor (Tempstar part number 1176763) is the main switching relay for your Tempstar TCH660GKA100 condensing unit. When the 24-volt coil is energized by a thermostat call for cooling, the contactor closes its line-voltage contacts and powers the compressor and condenser fan motor. It is a 2-pole device rated at 40 amps with a 24V control coil. A worn contactor is among the most common causes of an outdoor unit that hums but won't start, chatters, or fails to shut off. Pitted, welded, or burned contacts lead to hard starts and accelerated compressor wear.
