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.

Overview

This is a genuine OEM single-pole definite-purpose contactor (part number 1050699) for the ICP/Tempstar/Heil YG018GB1 heat pump. Rated at 25 amps with a 24-volt control coil, this contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. When the 24V coil is energized, the contacts close and pass line voltage to the compressor; when the call ends, the contacts open. Pitted, welded, or chattering contacts are one of the most common reasons a condensing unit fails to start, hums, or trips the breaker. Replacing a worn contactor is an inexpensive way to restore reliable operation.
