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 2-pole, 40-amp contactor (part #1178211) with a 24V coil is the main switching relay for your ICP Tempstar Heil RGS091HRCA0AAA condensing unit. When the thermostat calls for cooling, the 24V control signal energizes the coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. Contactors are high-wear parts: the contacts arc every time they open and close, eventually pitting, welding shut, or chattering. A failed contactor is a leading cause of a unit that won't start, won't shut off, or hums without engaging. This double-pole, 40A rating provides solid headroom for 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.
