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 genuine OEM contactor (part number 1066570) is a 2-pole, 40-amp electrical switch with a 24V control coil, built for the ICP/Tempstar/Heil ZAEB030CLA1 condensing unit. The contactor is the heavy-duty relay that delivers line voltage to the compressor and condenser fan motor on every cooling call. A low-voltage 24V signal energizes the coil, pulling both poles closed so power flows to the compressor and fan. Contactors are high-wear components — their contacts arc and pit with each of the many thousands of cycles they perform, eventually burning, welding, or failing to close. Telltale symptoms include a unit that won't start, loud humming or chattering, a compressor that never shuts off because the contacts welded shut, or visibly scorched terminals. Swapping in a fresh OEM contactor restores reliable, quiet switching.
