ICP 2-Pole 30A Contactor for RGS090SFCA0AAA — 24V Coil | Ships Today

Overview

This is the OEM 2-pole, 30-amp contactor (part number 1178074) with a 24-volt coil for the ICP / Tempstar / Heil RGS090SFCA0AAA system. The contactor is the electrically operated switch that closes the high-voltage circuit to the compressor and condenser fan motor whenever the thermostat calls for cooling. Its 24V control coil is energized by the low-voltage circuit, pulling the double-pole contacts closed to pass line voltage to the load. Contactors are a common wear item — the contacts pit, burn, or weld over thousands of cycles. A failing contactor causes no-cool calls, chattering, buzzing, or a compressor that won't start or won't shut off.

Specifications

Compatibility

Built for the ICP RGS090SFCA0AAA and other ICP-family units (Tempstar, Heil, Comfortmaker) specifying a 2-pole 30A contactor with a 24V coil. Verify the pole count, amp rating, and coil voltage against your old contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the unit and breaker; verify zero voltage with a multimeter on all terminals.
2. Access — Remove the control-box / service panel to expose the contactor.
3. Document — Photograph every line, load, and 24V coil wire before disconnecting.
4. Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its mounting.
5. Install — Mount the new contactor, land each wire on the matching terminal per your photo, and torque connections snug.
6. Test — Restore power, call for cooling, and confirm the contacts pull in cleanly and the compressor/fan energize.

Signs You Need a Replacement

• Pitted, burned, or welded contacts
• Loud buzzing, humming, or chattering at the contactor
• Compressor/condenser fan won't start or won't shut off
