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 2-pole, 30-amp contactor with a 24-volt coil (part number 1178074) is the primary switching relay for the ICP / Tempstar / Heil RGS101LTCB0AAA system. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed, sending line voltage to the compressor and condenser fan motor. Contactors are high-wear components: their contacts pit, arc, and burn over thousands of cycles. A failing contactor causes hard starts, chattering, welded contacts that won't shut the unit off, or a system that won't start at all. Replacing it with the correct 30A 2-pole OEM part restores clean, reliable switching.

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.
