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

These genuine ICP 2-pole definite-purpose contactors switch line power to the compressor and condenser fan motor on your RGS150HFAB0AGAA packaged unit. The set covers both the 30-amp version (part 1178074) and the 40-amp version (part 1178211), each with a 24-volt control coil. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed to deliver high-voltage power to the compressor and fan. Pitted, welded, or chattering contacts are one of the most common causes of a no-cool condition, hard starting, or a unit that won't shut off. Match the amp rating to your original contactor before installing.
