ICP 2-Pole 30A 24V Contactor for RGS102LDAA0AAA — OEM 1178074 | Ships Today

Overview

This is the OEM 2-pole, 30-amp definite purpose contactor (part number 1178074) with a 24-volt coil for the ICP/Tempstar/Heil RGS102LDAA0AAA system. The contactor is the electrically operated switch that energizes the compressor and condenser fan when the thermostat calls for cooling. When the 24V coil receives the call, it pulls the contacts closed and sends line voltage to the outdoor unit. Contactors are high-wear items: the contacts pit and burn over thousands of cycles, the coil can fail open, and ants or debris can jam the armature. A failing contactor causes no-cool calls, chattering, welded contacts that won't shut off, or a humming coil that won't pull in.

Specifications

Compatibility

Direct fit for the ICP RGS102LDAA0AAA and the shared ICP platforms marketed as Tempstar, Heil, and Comfortmaker that specify a 2-pole 30A 24V contactor. Verify pole count, amp rating, and coil voltage against your existing part before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage across the line terminals with a multimeter.
2. Access — Remove the unit electrical service panel.
3. Document — Photograph all line, load, and 24V coil wiring before disconnecting.
4. Remove — Transfer wires one at a time to avoid mix-ups, or label each lead, then unmount the old contactor.
5. Install — Mount the new contactor and reconnect every wire to the matching terminal per your photos.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan energize.

Signs You Need a Replacement

• Compressor and condenser fan won't start on a cooling call
• Loud chattering or buzzing from the contactor
• Pitted, burned, or welded contacts that won't open
