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 OEM 40-amp definite-purpose contactor (part number 1176763) is the primary switching relay for the ICP RHX048K0XA0AAA heat pump. The contactor is energized by the 24-volt control circuit and uses its electromagnetic coil to close two sets of heavy-duty silver-cadmium contacts, delivering line-voltage power to the compressor and condenser fan motor every time there is a call for heating or cooling. Rated for 40 FLA per pole, it is a 2-pole design built to handle the high inrush current of a scroll compressor start. Failure symptoms include a system that will not start, audible chattering or buzzing at the outdoor unit, pitted or welded contacts that keep the compressor running continuously, and visible arcing or burnt terminals. Because it cycles thousands of times per season, the contactor is one of the most common wear items on any condensing unit.
