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 contactor (part number 1171554) is a 2-pole, 30-amp definite-purpose contactor with a 24-volt coil for the ICP Tempstar Heil RGS210LSCA0AAAA. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor when the 24V control circuit calls for cooling. Its contacts carry heavy current and eventually pit, burn, or weld from arcing, while the coil can fail open. A bad contactor leaves the outdoor unit dead or, when contacts weld, prevents the unit from shutting off.

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.
