Overview

This genuine OEM 2-Pole 30A Contactor (Part No. 1178074) is the switching relay for the ICP/Tempstar/Heil RGS101LDCB0AAA. When the thermostat calls for cooling, the 24-volt control coil energizes and pulls the contacts closed, sending line voltage to the compressor and condenser fan motor. Contactors are one of the most common HVAC failure points: the contacts pit, arc, and weld over thousands of cycles, while ants and debris can foul the coil. A failing contactor causes a unit that won't start, chatters, or won't shut off because the contacts have welded together. Replacing it restores clean, reliable switching.
