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 genuine OEM 2-pole, 30-amp contactor (part number 1171554) is the electrical switch that energizes the compressor and condenser fan on ICP, Heil, and Tempstar systems associated with the RGS303SRFA0AAAA. A 24-volt coil pulls in the contactor when the thermostat calls for cooling, closing two sets of heavy-duty silver-alloy contacts that pass line voltage to the outdoor unit. Because it cycles every time the system runs, the contactor is a high-wear component and a frequent cause of no-cool service calls.

Over time the contacts pit, burn, and arc, leaving the system unable to start reliably or causing it to stick on and run continuously. A failed coil will prevent pull-in entirely, while welded contacts can keep the compressor energized even when the thermostat is satisfied. Replacing the contactor with the correct OEM 30A / 24V part restores clean, dependable switching and protects the compressor from low-voltage and chatter damage.

Compatibility

Designed as a direct replacement for the RGS303SRFA0AAAA and other ICP / Heil / Tempstar / Comfortmaker units calling for the 1171554 2-pole 30A contactor with a 24V coil. Verify the amperage, pole count, and coil voltage against your existing contactor before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter at the contactor line terminals.
Access — Remove the condensing-unit electrical access panel.
Document — Photograph all line, load, and coil wiring before disconnecting anything.
Remove — Transfer wires one at a time or label them, then unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the 24V coil leads are correct.
Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start without chatter.

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.
