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.

Overview

This is a genuine OEM 3-pole, 35-amp contactor (part number 1280465) with a 24V coil for the ICP/Tempstar/Heil RH5420484. The contactor is the electrically operated switch that sends high-voltage power to the compressor and condenser fan motor when the thermostat calls for cooling. The 24V coil pulls the contacts closed; when the call ends, the contacts open and de-energize the outdoor unit. Pitted, welded, or chattering contacts are one of the most common no-cooling failures in the field. Symptoms include an outdoor unit that won't start, a humming or buzzing contactor that won't pull in, or a compressor that runs continuously because the contacts have welded shut.

Installation Guide

Safety First — Pull the outdoor disconnect and shut the breaker, then verify zero voltage with a multimeter across all contactor terminals.
Access — Remove the condenser electrical access panel.
Document — Photograph all line, load, and 24V coil wires before disconnecting.
Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from the bracket.
Install — Mount the new contactor, land each wire on the matching terminal per your photo, and connect the 24V coil leads.
Test — Restore power and place a cooling call; the contactor should pull in cleanly and start the compressor and fan.

Is this contactor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
