ICP 2-Pole 30A Contactor for RGS102HTCB0AAA — 24V Coil | Ships Today

Overview

This OEM 2-pole 30-amp definite-purpose contactor (part 1178074) with a 24-volt coil is the power-switching relay for the ICP Tempstar Heil RGS102HTCB0AAA system. When the thermostat calls for cooling, the 24V coil pulls the contacts closed and energizes the compressor and condenser fan; when the call ends, it drops out and cuts line power. Contactors are high-wear parts — the contacts arc and pit with every cycle. Failure symptoms include a unit that won't start, chattering or buzzing at the contactor, contacts that weld closed (so the compressor never shuts off), or visible burning and pitting on the contact points.

Specifications

Compatibility

Fits the ICP Tempstar Heil RGS102HTCB0AAA and a wide range of ICP-family condensing units and air handlers calling for a 2-pole, 30A, 24V-coil contactor. Verify amp rating and coil voltage against the original 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 service panel.
3. Document — Photograph every line, load, and coil wire before disconnecting.
4. Remove — Unfasten the old contactor and transfer wires one at a time, or label each lead.
5. Install — Mount the new contactor, reconnect line, load, and 24V coil leads per your photo, and confirm tight terminals.
6. Test — Restore power and verify the contactor pulls in on a cooling call and drops out cleanly when satisfied.

Signs You Need a Replacement

• Unit won't start or starts intermittently
• Loud chattering or buzzing from the contactor
