ICP Contactor for RGS303HTEA0AAAA – 2-Pole 30A & 3-Pole 60A 24V Coil | Ships Today

Overview

These OEM 24V-coil contactors switch line power to the compressor and condenser fan circuits associated with the ICP Tempstar Heil RGS303HTEA0AAAA system. When the thermostat calls for cooling, the 24V coil pulls the contacts closed to energize the high-voltage load. The kit covers both the 2-pole 30A contactor (part 1171554) and the 3-pole 60A contactor (part 1183142). Contactor failure shows up as a system that won't start, chattering or buzzing at the contactor, pitted or welded contacts that won't drop out, or a unit that runs continuously. Both use a 24V coil for direct compatibility with the control circuit.

Specifications

Compatibility

Direct-fit replacement contactors for the ICP Tempstar Heil RGS303HTEA0AAAA system and other ICP-family units specifying parts 1171554 or 1183142. Match coil voltage (24V), amp rating, and pole count to the contactor being replaced.

Installation Guide

1. Safety First – Disconnect power at the disconnect and breaker; verify zero voltage with a multimeter.
2. Access – Remove the unit's electrical-access panel.
3. Document – Photograph all line, load, and coil connections before disconnecting.
4. Remove – Transfer wires from the old contactor, then unfasten it from its mounting.
5. Install – Mount the matching replacement contactor and reconnect line, load, and 24V coil leads exactly per your photo.
6. Test – Restore power, call for cooling, and confirm the contactor pulls in cleanly and drops out fully when satisfied.

Signs You Need a Replacement

• System won't start on a cooling call despite 24V at the coil.
• Loud buzzing or chattering at the contactor.
• Pitted, burnt, or welded contacts.
• Unit runs continuously because contacts won't open.
