ICP 2-Pole 30A Contactor for RGS091LSCB0AAA — 24V Coil | Ships Today

Overview

This OEM 2-pole 30-amp contactor (part 1178074) with a 24-volt control coil is the electrical switch that energizes the load circuit on the ICP RGS091LSCB0AAA. When the thermostat calls, the 24V coil pulls the contacts closed and passes line voltage to the connected component; when the call ends, the contacts open. Contactors are a common wear item — the silver contacts pit and burn from arcing over thousands of cycles, and the coil can fail open. Symptoms of a failing contactor include chattering, buzzing, welded-shut contacts that won't let the system turn off, or a unit that won't start at all.

Specifications

Compatibility

Built for the ICP / Tempstar / Heil RGS091LSCB0AAA and other systems specifying a 2-pole, 30A, 24V-coil contactor. Verify amperage rating, pole count, and coil voltage against your old part before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter.
2. Access — Remove the electrical access panel.
3. Document — Photograph every wire on the line, load, and coil terminals before disconnecting.
4. Remove — Transfer wires one at a time or label them, unscrew the old contactor, and lift it out.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo.
6. Test — Restore power, initiate a call, and confirm the contacts pull in cleanly with no chatter.

Signs You Need a Replacement
