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 40-amp definite purpose contactor (OEM #1176763) is the switching relay for the ICP/Heil/Tempstar WCH3602GKR2 heat pump. The contactor uses a low-voltage 24V control signal from the thermostat to close its line-voltage contacts, energizing the compressor and condenser fan motor. Over time the contacts pit, burn, and weld from constant arcing. A failed contactor is one of the most common causes of a condenser that won't start, that hums without running, or that won't shut off because the contacts have fused closed. Replacing it is a fast, low-cost repair that restores reliable compressor and fan operation.

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.
