ICP 2-Pole 30A Contactor for RGS120STAA0AGAA — 24V Coil | Ships Today

Overview

This genuine OEM 2-pole, 30-amp contactor with a 24-volt coil (part number 1178074) is the electrical switch that powers the high-voltage components in your ICP/Tempstar/Heil RGS120STAA0AGAA system. When the control board or thermostat sends a 24V signal to the coil, the contactor closes its two poles and energizes the load. Contactors fail from pitted or welded contacts, a burned-out coil, or insect/debris intrusion that prevents the armature from pulling in. Symptoms include a humming or chattering contactor, contacts that stick closed so the unit won't shut off, or no operation at all. Installing the correct 2-pole 30A part restores reliable switching and protects downstream components.

Specifications

Compatibility

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage at the contactor terminals with a multimeter.
2. Access — Remove the electrical access panel.
3. Document — Photograph every wire and terminal position before disconnecting.
4. Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor.
5. Install — Mount the new contactor and transfer each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in cleanly with no chatter when the unit calls.

Signs You Need a Replacement

• Loud humming, buzzing, or chattering from the contactor
