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 definite-purpose contactors — a 2-pole 30A unit (P/N 1178074) and a 2-pole 40A unit (P/N 1178211), both with a 24-volt coil — switch the high-voltage power to the compressor and condenser fan motor in the ICP Tempstar Heil RGS101HDCB0AAA. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed to feed line voltage to the loads. Pitted, welded, or chattering contacts cause hard starts, no-cool conditions, and buzzing — the most common electrical failure in condensing units. Replacing with the correct OEM amperage rating restores reliable switching.
