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 definite-purpose contactor is the high-voltage switch that energizes the compressor and condenser fan motor in your ICP RHS181L0CA0AAAA heat pump. When the thermostat calls for cooling or heating, the 24V control coil pulls the contacts closed, sending line voltage to the outdoor unit. This listing covers ICP part numbers 1171554 (2-pole, 30A, 24V coil) and 1172449 (3-pole, 40A, 24V coil). A failed contactor is one of the most common no-cool service calls: pitted or welded contacts, a chattering or buzzing coil, or burnt terminals will keep the compressor from starting or running.
