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 40-amp definite-purpose contactor (part number 1176763) for the ICP/Heil/Tempstar RGX036KECA0AAA gas furnace and its associated switching circuit. A contactor is an electrically operated switch: a 24-volt control signal energizes the coil, the contacts close, and line voltage passes to the load; remove the signal and a spring snaps the contacts open. This 2-pole unit is rated for 40A per pole with a 24VAC coil. Repeated arcing slowly pits and burns the contacts until they weld closed or fail to make contact, and the coil itself can open with age — producing a system that hums but won't start, won't shut off, or chatters under load. A fresh OEM contactor restores crisp, dependable switching and protects the rest of the system from voltage drop and contact 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.
