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 definite-purpose contactor (part number 1050699) for the Tempstar TCA036AKA5 condensing unit. It is a single-pole (1-pole) contactor rated for 25 amps with a 24-volt control coil. The contactor serves as the high-voltage switch for the compressor and condenser fan motor: on a thermostat cooling call, the 24V coil energizes and closes the main contacts, sending line voltage to the load. Repeated arcing across the contacts wears them down, which is why a worn contactor is one of the most common causes of no-cool failures. Look for chattering, hard starting, a unit that won't cycle off, or a unit that won't start at all.
