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 genuine OEM single-pole contactor (part number 1050699) is the 25-amp, 24V-coil switching relay for the Tempstar TCH030AKD1 condensing unit. The contactor is the heavy-duty switch that delivers line voltage to the compressor and condenser fan motor whenever the 24V coil is energized by a cooling call. Over time the contact points pit, arc, and burn, or the coil itself fails — leaving the outdoor unit silent while the indoor blower still runs, or causing the unit to chatter, buzz, or weld closed and run continuously. A 1-pole contactor switches one leg of power and relies on the always-closed second leg, which is standard on many ICP-family residential condensers. Replacing a worn contactor is one of the most common and inexpensive HVAC service repairs.

Installation Guide

Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan start.
