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 (part number 1178074) with a 24-volt coil for the ICP / Tempstar / Heil RGS102HRAB0AAA. The contactor is the high-voltage switch that powers the compressor and condenser fan: when the thermostat calls for cooling, the 24V coil pulls the contacts closed and sends line voltage to the outdoor unit; when the call ends, the contacts open and the unit shuts down. Because it cycles thousands of times per season under inductive load, the contacts eventually pit, burn, or weld shut. Welded contacts keep the compressor running with the thermostat satisfied; pitted contacts cause chatter, hard starts, and dropped voltage. A buzzing, sticking, or visibly burned contactor should be replaced before it damages the compressor.

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.
