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 single-pole definite purpose contactor (part number 1050699) for the Tempstar TCH036AKC3 condensing unit. The contactor is the electromechanical switch that powers the compressor and condenser fan motor each time the thermostat calls for cooling. A 24-volt control signal energizes the coil, pulling in a set of 25-amp contacts that feed line voltage to the outdoor equipment. Because it cycles thousands of times per season, the contactor's contacts gradually pit, burn, or weld from arcing — one of the most common reasons an outdoor unit hums but won't start, or won't shut off. A new contactor is a low-cost repair that restores dependable operation and protects the compressor.

Remove — Disconnect the 24V coil leads and the line/load wires, then unscrew the contactor from its bracket.
Install — Mount the new contactor, move each wire to the matching terminal per your photo, and tighten all connections.
Test — Restore power, call for cooling, and confirm the contactor pulls in and the compressor and fan start.
