ICP 2-Pole 30A 24V Contactor for RGS091LDCB0AAA — OEM 1178074 | Ships Today

Overview

This OEM definite-purpose contactor (part number 1178074) is a 2-pole, 30-amp relay with a 24-volt coil used in ICP, Tempstar, and Heil RGS091-series equipment. When the thermostat or control board energizes the 24V coil, the contactor's electromagnet pulls the contacts closed and routes line-voltage power to the load. Contactors are high-cycle wear items: the contacts pit, burn, and weld over thousands of operations, while the coil can open or buzz. Symptoms include a unit that won't start, chattering at the contactor, or a load that won't shut off because the contacts have welded closed. This exact-fit OEM contactor restores reliable switching.
