This OEM 2-pole, 30-amp definite-purpose contactor (ICP part 1178074) uses a 24-volt control coil to switch line voltage to the compressor and condenser fan motor on the ICP / Tempstar / Heil RGS090STAB0AAA system. When the thermostat calls, the 24V coil pulls the contacts closed to energize the high-voltage circuit. Over time the silver contacts pit, burn, and weld from arcing, while the coil can fail open. A bad contactor is one of the most common causes of a unit that hums but won't start, chatters, or runs continuously even after the call ends.
