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

OEM definite-purpose contactors for the ICP / Heil / Tempstar RHS243H0EA0AAAA heat pump, all using a 24VAC control coil. This listing covers the 2-pole 30A contactor (P/N 1171554), the 3-pole 40A contactor (P/N 1172449), and the 3-pole 60A contactor (P/N 1183142). The contactor is the heavy-duty switch that closes line voltage to the compressor and outdoor fan motor whenever the thermostat energizes the 24V coil. Pitted, welded, or chattering contacts are one of the most common reasons a condenser won't start, hums without running, or short-cycles.

Should I use OEM or aftermarket for my ICP contactor?
