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

These genuine OEM contactors switch line-voltage power to the major loads of the ICP / Heil / Tempstar RGS210HREA0AAAA system. The set covers the 2-pole 30-amp contactor (part 1171554) and the 3-pole 40-amp contactor (part 1172449), both driven by a 24V control coil. When the thermostat calls, the 24V coil pulls the contacts closed and energizes the compressor and/or fan circuit; when the call ends, the coil drops out and breaks the load. Contactors are high-wear components — their contacts arc on every cycle and eventually pit, weld shut, or fail to pull in. Symptoms include a system that won't start, won't shut off, hums without engaging, or trips on contact failure. Replacing a worn contactor restores clean, reliable switching.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?
