ICP 2-Pole Contactor for RGS090SRCB0AAA — 30A 24V Coil | Ships Today

Overview

This OEM 2-pole definite purpose contactor (part number 1178074) is the electromechanical switch that energizes the compressor and condenser fan circuit in your ICP RGS090SRCB0AAA system. Rated at 30 amps with a 24-volt control coil, the contactor closes when the thermostat calls for cooling, sending line voltage to the compressor and fan motor. Over time the contacts pit, arc, and weld from repeated switching, which leads to a system that won't start, chatters audibly, or runs continuously because the contacts have fused closed. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs.

Specifications

Compatibility

Engineered as a direct OEM replacement for the ICP / Tempstar / Heil RGS090SRCB0AAA and closely related furnace and air-handler platforms that use a 30A 2-pole 24V coil contactor. Always confirm your existing contactor's amp rating, pole count, and coil voltage against the failed unit before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before touching any wiring.
2. Access — Remove the service panel to expose the contactor.
3. Document — Photograph all line, load, and coil wiring before disconnecting anything.
4. Remove — Label and transfer wires one at a time, then unscrew the old contactor from its bracket.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with no chatter.

Signs You Need a Replacement

• System won't start or hums but the compressor never engages
• Loud buzzing or chattering from the contactor when the thermostat calls
• Visibly pitted, burned, or welded contacts
• Unit runs continuously because the contacts are stuck closed
