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 definite-purpose contactor (part number 1059574) for the Tempstar TCA460AKC3 condensing unit. The contactor is a 2-pole, 40-amp electrical switch with a 24-volt coil that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V control signal reaches the coil, the magnetic field pulls the contacts closed, sending line voltage to the outdoor unit. A failed contactor is one of the most common reasons an air conditioner will not start: pitted, welded, or chattering contacts interrupt power and leave the system unable to cool. Replacing this 40A 2-pole contactor restores reliable switching and protects the compressor from voltage problems.

Compatibility

Engineered as a direct OEM fit for the Tempstar TCA460AKC3 condensing unit. This 40A 24V 2-pole contactor (PN 1059574) is also used across many ICP-family condensers including Heil, Comfortmaker, and other Tempstar models that share the same 2-pole 40-amp specification.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching any wiring.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph all wire connections to the line, load, and 24V coil terminals before disconnecting anything.
Remove — Label and disconnect the line and load wires, pull the two coil wires, then unscrew the old contactor from its bracket.
Install — Mount the new 1059574 contactor, reconnect line, load, and coil wires exactly per your photo.
Test — Restore power, call for cooling, and confirm the contacts pull in and the compressor and fan start.

Signs You Need a Replacement
