ICP 2-Pole Contactor for RGS101HTAA0AAAA — 30A/40A 24V Coil | Ships Today

Overview

This OEM 2-pole definite-purpose contactor is the electrically operated switch that energizes the compressor and condenser fan motor on equipment paired with the ICP RGS101HTAA0AAAA system. When the thermostat calls for cooling, the 24-volt control circuit energizes the contactor coil, pulling the contacts closed and delivering line voltage to the high-amperage loads. Two amperage ratings fit this model: part 1178074 (30A) and part 1178211 (40A), both with a 24V coil. Pitted, welded, or chattering contacts are a leading cause of no-cool failures, so a worn contactor should be replaced promptly.

Specifications

Compatibility

Direct-fit replacement for the ICP / Tempstar / Heil / Comfortmaker RGS101HTAA0AAAA. Match the amperage rating to the contactor currently installed in your unit. The 24V coil is standard across most residential HVAC control circuits.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter before touching any wiring.
2. Access — Remove the unit's electrical service panel.
3. Document — Photograph all wire positions on the line and load sides and the coil terminals before disconnecting.
4. Remove — Label and disconnect each wire, then unscrew the old contactor from the mounting bracket.
5. Install — Mount the new contactor and reconnect every wire exactly per your photo.
6. Test — Restore power, call for cooling, and confirm the contacts pull in cleanly with no chatter.

Signs You Need a Replacement

• Unit won't start or only starts when you tap the contactor
• Loud humming, buzzing, or chattering from the contactor
• Visible pitting, burning, or melted contacts
• Compressor runs continuously because contacts are welded closed
