ICP 2-Pole 30A Contactor for RGS101SFAB0AAAA — 24V Coil | Ships Today

Overview

This OEM 2-pole 30-amp contactor with a 24V coil, part number 1178074, is the switching device that sends line voltage to the compressor and condenser fan motor in the ICP Tempstar Heil RGS101SFAB0AAAA system. When the thermostat calls, the 24-volt coil pulls the contacts closed and energizes the high-voltage loads; when the call ends, the contacts open. Contactors are a high-wear part — the contacts arc on every cycle and eventually pit, burn, or weld. A failed contactor leaves the outdoor unit dead, stuck running, or buzzing, and is one of the most common no-cooling/no-heat-pump service calls.

Specifications

Compatibility

Fits the ICP Tempstar Heil RGS101SFAB0AAAA and other ICP-family units that use a 2-pole 30A definite-purpose contactor with a 24V coil. Confirm pole count, amp rating, and coil voltage against your old part before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the unit's electrical panel to expose the contactor.
3. Document — Photograph every line, load, and 24V coil wire before removing them.
4. Remove — Transfer wires one at a time or label them, then unscrew the old contactor from its mount.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in on a call and the compressor and fan start normally.
