Overview

This OEM 2-pole, 30-amp definite purpose contactor, part number 1178074, switches the high-voltage power feeding the compressor and condenser fan motor in the ICP/Heil/Tempstar RGS101LRCA0AAA system. A 24V control signal from the thermostat circuit energizes the coil, which pulls the contacts closed and sends line voltage to the outdoor unit. Over time the contact points pit, burn, and weld from repeated arcing, while the coil can fail open. Symptoms of a failing contactor include a humming or chattering outdoor unit, a condenser that won't start, contacts that stick closed so the unit never shuts off, or visible burn marks and pitting on the contact pads. This direct OEM replacement restores reliable, clean switching.
