ICP 2-Pole 30A Contactor for RGS102STCA0AAA — 24V Coil | Ships Today

Overview

This genuine OEM 2-pole, 30-amp contactor (part number 1178074) with a 24-volt control coil is the main switching device for the ICP / Heil / Tempstar RGS102STCA0AAA system. When the thermostat calls for cooling, 24V is applied to the coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. The two power poles switch both legs of the line for safe, complete disconnection on the off cycle. Contactors are a high-wear item: their contacts arc every time they engage, eventually pitting and burning. A worn contactor causes hard starts, buzzing, welded contacts that won't release, or a system that won't energize at all.

Specifications

Compatibility

Designed for the ICP family RGS102STCA0AAA and related models calling for a 2-pole 30A contactor with a 24V coil. Match the amp rating, pole count, and coil voltage to your old contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter.
2. Access — Remove the electrical panel to expose the contactor.
3. Document — Photograph every line, load, and coil wire before disconnecting.
4. Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its base.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power, call for cooling, and confirm the contacts pull in and the compressor and fan energize.

Signs You Need a Replacement

• Loud buzzing or chattering from the contactor on a cooling call
• Burned, pitted, or welded contacts that won't release
• System won't start, or trips/hard-starts the compressor
