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 1-pole 30-amp definite purpose contactor with a 24V coil and shunt for the ICP / Heil / Tempstar WCH3242GKR500 condensing unit. The contactor is the electrically operated switch that delivers line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil pulls the contacts closed; the integrated shunt provides a maintained circuit path for safe operation. Contactors are one of the most common failure points in a condenser because the contacts arc and pit with every cycle. Symptoms of a failing contactor include a unit that won't start, chattering or buzzing at the contactor, pitted or welded contacts, and a compressor that runs continuously because the contacts are stuck closed.
