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 2-pole, 30-amp contactor (part number 1178074) is the main power-switching relay for your ICP RHS036S0BB0AAAA heat pump. A 24-volt control coil, energized by the thermostat, pulls in two sets of line-voltage contacts to deliver power to the compressor and condenser fan; when the call ends, the contacts open and the outdoor unit stops. Contactors are a leading cause of no-cool and no-heat service calls because their contacts pit and burn from repeated arcing, while the coil can open from age or a power surge. The result is a unit that buzzes, chatters, fails to start, or runs nonstop because the contacts have welded shut.
