ICP 2-Pole 30A Contactor for RGS102LRBA0AAA — 24V Coil | Ships Today

Overview

This genuine OEM 2-pole 30-amp contactor (part number 1178074) with a 24-volt coil is the electrical switch that powers loads on and off in your ICP/Tempstar/Heil RGS102LRBA0AAA system. When the 24V control circuit energizes the coil, the contactor pulls in and closes its line-voltage contacts; when the call ends, a spring opens them. Because the contacts make and break high current thousands of times, they are a common wear item — points pit, burn, weld shut, or chatter. A failed contactor causes a unit that won't start, won't shut off, or buzzes loudly. This 30A/2-pole rating ensures adequate current capacity and the safety margin the equipment was engineered for.

Installation Guide

1. Safety First — Disconnect power at the breaker/disconnect and confirm zero voltage with a multimeter.
2. Access — Remove the control/electrical access panel.
3. Document — Photograph every wire and terminal before disconnecting.
4. Remove — Label and disconnect the line, load, and 24V coil leads, then unbolt the old contactor from its mounting bracket.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in on a call and the system energizes normally.
