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 2-pole, 30-amp definite-purpose contactor with a 24-volt coil, OEM part number 1171554, for the ICP / Tempstar / Heil RGS210SFAA0AAAA. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor. When the thermostat calls for cooling, 24V is applied to the contactor coil, the armature pulls in, and both poles close to deliver line voltage to the load. A worn contactor is one of the most common no-cool service calls: the contacts pit and burn over thousands of cycles until they no longer pass full current, or they weld shut so the compressor never shuts off. Symptoms include a buzzing or chattering contactor, a system that won't start on a cooling call, or a compressor that runs continuously.

Compatibility

Fits the ICP RGS210SFAA0AAAA and other ICP-built Tempstar, Heil, and Comfortmaker systems specifying a 2-pole 30A 24V coil contactor. A 30A 2-pole definite-purpose contactor is a common upgrade replacement, but confirm OEM 1171554 and the 24V coil before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condenser electrical access panel.
Document — Photograph all line, load, and coil wiring before disconnecting.
Remove — Transfer one wire at a time, or label each lead, then unbolt the old contactor.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo; verify the 24V coil leads.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement

Buzzing or chattering from the contactor when the system tries to start.
Burned, pitted, or welded contacts visible on the terminals.
Compressor that runs continuously and won't shut off (welded contacts).
No-cool call where 24V reaches the coil but the contacts won't close.

My AC clicks but the compressor won’t turn on. What’s wrong?

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

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.
