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 contactor with a 24V coil, part number 1171554, for the ICP / Tempstar / Heil RGS303SFEA0AAAA. The contactor is an electrically operated switch: when the 24V control signal energizes its coil, the contacts close and pass line voltage to the load. Over time the contacts pit, burn, and stick, which causes hard starting, chattering, or a component that simply will not energize. A failed or welded contactor can also leave a load running continuously. This OEM contactor is rated 30A across two poles with a 24V pull-in coil for a direct, no-modification replacement.

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.
