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 OEM 2-pole, 30-amp definite-purpose contactor with a 24V coil (part 1171554) is the factory switching relay for the ICP/Tempstar/Heil RGS210LTEA0AAAA system. The contactor uses a low-voltage 24V signal from the thermostat or control board to close two sets of high-current contacts, energizing the compressor and/or condenser fan motor. It is the workhorse switch that starts the system every cooling cycle.

Because the contacts make and break high inrush current thousands of times, they pit, corrode, and eventually weld or fail to close. A failing 30A contactor causes no-start conditions, chattering, buzzing, or — when contacts weld shut — a compressor that runs continuously and won't shut off. Burned or pitted contacts also cause low voltage to the load and premature compressor wear.

Compatibility

This is the OEM-specified 2-pole 30A 24V-coil contactor for the ICP-family RGS210LTEA0AAAA unit and matching Tempstar, Heil, Comfortmaker, and Arcoaire systems on the same platform. Verify pole count (2), amp rating (30A), and coil voltage (24V) against your existing contactor before ordering.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage at the line terminals with a multimeter.
Access — Remove the electrical access panel.
Document — Photograph all line, load, and coil wires before disconnecting anything.
Remove — Transfer wires one at a time or label them, then unscrew the old contactor from the bracket.
Install — Mount the new contactor, then land each wire on its matching terminal per your photo, torquing the lugs snug.
Test — Restore power and call for cooling. Confirm the contactor pulls in cleanly, both poles close, and the system energizes without chatter.

Signs You Need a Replacement

System won't start on a cooling call
Loud buzzing, humming, or chattering from the contactor
Contacts welded shut — system runs and won't shut off
Visibly pitted, burned, or arcing contacts

Is this contactor compatible with Bryant or Payne too?

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.
