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 40-amp definite-purpose contactor (part #1176763) is the main switching relay for the ICP/Tempstar/Heil WCH3602GKR4 condensing unit. When the thermostat calls for cooling, the 24-volt coil closes the contacts and feeds line voltage to the compressor and condenser fan motor. Carrying full load current on every cycle makes the contacts a high-wear item — pitting, burning, and chatter are common failure modes that lead to hard starts, intermittent cooling, or a unit that hums but won't engage. A fresh 40A contactor restores clean, full-voltage switching to the compressor circuit.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
