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, 40-amp definite purpose contactor (OEM 1173690) with a 24V coil is the switching relay for the ICP / Heil / Tempstar WPA3602000RKB1 heat pump. When the thermostat calls for cooling or heating, the 24V control signal energizes the contactor coil, pulling the contacts closed to send line voltage to the compressor and condenser fan motor. Contactors wear out from millions of switching cycles: contacts pit and burn, the coil weakens, and the plunger sticks. Common failure symptoms include a chattering or buzzing contactor, contacts welded closed so the unit never shuts off, pitted or blackened contact points, and a unit that won't start because the coil no longer pulls in. A fresh 40A contactor restores clean, reliable switching and protects the compressor from voltage drop.
