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 1-pole, 30-amp definite-purpose contactor (part #1172472) with integrated shunt is the switching relay for the ICP/Heil/Tempstar WCH4244GKB100 heat pump. When the thermostat calls for cooling or heating, the 24V control circuit energizes the contactor coil, pulling the contacts closed to send line voltage to the compressor and condenser fan motor. The shunt provides a continuous path for crankcase-heater or accessory loads when the contactor is open. Contactors are high-wear parts: every cycle draws an arc across the contacts, which slowly pits and burns them. Over time the contacts weld shut (system runs constantly) or burn open (system won't start). This direct replacement restores clean, reliable switching. Symptoms of a failing contactor include chattering, a loud hum, no compressor start, or a unit that won't shut off.
