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.

Overview

This is a genuine OEM single-pole definite purpose contactor (OEM part #1050699) for the Tempstar TCH236AKAA heat pump. The contactor is the high-amperage relay that delivers line voltage to the compressor and condenser fan motor every time the thermostat calls for cooling or heating. A 24V signal energizes the coil, closing the contacts to power the outdoor unit. This part is rated for 25 amps with a 24V coil and a single pole. Failure symptoms include a humming unit that won't start, chattering at the contactor, pitted or welded contacts, an outdoor fan stuck running, or no outdoor operation despite a cooling call.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph all line, load, and 24V coil wiring before disconnecting anything.
Remove — Transfer the line and load conductors off the old contactor one at a time, disconnect the two 24V coil leads, and unscrew the contactor from its bracket.
Install — Mount the new contactor, reconnect line, load, and 24V coil wires exactly per your photos, and torque all lugs tight.
Test — Restore power, start a cooling call, and verify the contacts pull in and the compressor and fan run cleanly with no chatter.

Signs You Need a Replacement

Loud buzzing, humming, or chattering from the outdoor electrical compartment.
Pitted, burned, or welded contacts on the old contactor.
Compressor and fan won't start even with 24V present at the coil.
Outdoor fan runs continuously because the contacts are stuck closed.
