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-current switch that energizes the compressor and condenser fan in your ICP RHS243S0EA0AAAA heat pump. It carries a 2-pole, 30-amp main contact set actuated by a 24V coil (OEM part 1171554); the same control circuit also uses a 3-pole 40A 24V contactor, OEM part 1172449, on larger configurations. When the thermostat calls for cooling or heating, the 24V coil pulls the contacts closed and line voltage flows to the compressor. Pitted, welded, or chattering contacts are the most common failure — symptoms include a unit that won't start, a compressor that hums but won't run, or contacts that stick closed and won't let the system cycle off.
