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 single-pole definite purpose contactor (part number 1172472) is the switching relay for the ICP / Tempstar / Heil WPG3304040RKC1. Rated 30 amps with a 24-volt control coil and an integrated shunt, it energizes the compressor and condenser fan whenever the thermostat calls for cooling. Contactors are one of the most common HVAC failure points: the contacts arc and pit with every cycle, eventually welding shut, chattering, or refusing to pull in. A failed contactor leaves the outdoor unit either dead or unable to shut off. Replacing it with the correct OEM part restores reliable switching and protects the compressor from chatter-induced damage.

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.
