Overview

This ICP 2-Pole 30 Amp Contactor (OEM part 1178074) is the electromagnetic relay that switches line voltage to the system's high-draw loads in the ICP / Tempstar / Heil RGS090STBB0AAA. When the 24V control circuit energizes the coil, the contactor pulls in and closes both poles to deliver power; when the call ends, it drops out and cuts power. Contactors are high-wear components — the contacts erode, pit, and weld over thousands of switching cycles, and the coil can burn open. Failure shows up as a system that won't start, chatters, hums, or refuses to shut off because the contacts have fused closed. This OEM-rated 30A, 2-pole, 24V-coil contactor restores reliable, clean switching.

Should I use OEM or aftermarket for my ICP contactor?
