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 single-pole 30 amp contactor with shunt (part number 1172472) is the main switching relay for the ICP/Heil/Tempstar WJH342000KTP0A2 heat pump. Its 24V control coil is energized by the thermostat call, closing the main contacts to feed line voltage to the compressor and outdoor fan motor. The integrated shunt provides the proper auxiliary path for this model. A worn contactor causes the most common no-cooling and no-heating symptoms on a heat pump: a buzzing outdoor unit that will not engage, hard starts, or a compressor that runs nonstop because the contacts have welded closed. Replacing it restores clean, reliable starting and protects the compressor.
