ICP 2-Pole 30A Contactor for RGS150SFCB0AAAA — 24V Coil | Ships Today

Overview

This is the genuine OEM 2-pole, 30-amp contactor (part number 1178074) for the ICP/Heil/Tempstar RGS150SFCB0AAAA. A contactor is an electrically controlled switch: when the 24V control circuit energizes the coil, the contacts close and pass line voltage to the load. When a contactor fails, the most common symptoms are a unit that hums but won't start, chattering at the relay, pitted or welded contacts that won't open, or a coil that no longer pulls in. Because the contacts carry the full running current, they erode over time and are one of the most common service-replacement parts in HVAC equipment.

Specifications

Compatibility

Engineered as the factory replacement for the ICP RGS150SFCB0AAAA and shared across many ICP-family (Heil, Tempstar, Comfortmaker) systems that use a 2-pole 30A / 24V-coil contactor. Always confirm your existing contactor's pole count, contact amperage, and coil voltage against the part you are replacing before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and the unit disconnect, then verify zero voltage with a multimeter before touching any wiring.
2. Access — Remove the service panel to expose the control compartment.
3. Document — Photograph all line- and low-voltage wire connections before disconnecting anything.
4. Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor from its mounting.
5. Install — Mount the new contactor and reconnect every wire exactly as photographed; verify all spade and screw terminals are tight.
6. Test — Restore power and confirm the contactor pulls in cleanly and the unit energizes without chatter.

Signs You Need a Replacement

• Unit hums but the compressor/blower won't start.
• Visible pitting, burning, or welded contacts.
• Audible chattering or buzzing from the contactor.
• Coil no longer pulls the contacts closed when energized.
