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 1-pole definite purpose contactor (part number 1050839) for the Tempstar TCH048AKC2 condensing unit. The contactor is the electrically-controlled switch that powers your outdoor compressor and condenser fan motor. When the thermostat calls for cooling, the 24V control circuit energizes the contactor coil, pulling the contacts closed and sending line voltage to the compressor. Rated for 35 amps with a 24-volt coil and a single pole, it is one of the most common failure points in an air conditioning system. Symptoms of a failing contactor include a system that won't start, a humming or chattering sound at the outdoor unit, pitted or welded contacts that keep the compressor running, or visible burning and corrosion on the contact points. Replacing a worn contactor restores reliable switching and protects the compressor from voltage problems.
