ICP 2-Pole 30A Contactor 24V Coil for RGS303LDEA0AAAA — OEM 1171554 | Ships Today

Overview

This is a genuine OEM 2-pole, 30-amp definite-purpose contactor with a 24-volt coil (part number 1171554) for the ICP / Tempstar / Heil RGS303LDEA0AAAA system. The contactor is the electromechanical switch that closes the high-voltage circuit to the compressor and condenser fan when the 24V control signal energizes its coil. Pitted, welded, or chattering contacts are one of the most common no-cool and no-start failures — symptoms include a humming contactor that won't pull in, intermittent operation, or contacts that stick closed and won't shut the unit off.

Specifications

Compatibility

Designed for the ICP-built RGS303LDEA0AAAA and shared across the Tempstar, Heil and Comfortmaker family. Verify your existing contactor is a 2-pole, 30A unit with a 24V coil and matches OEM 1171554 before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the line terminals with a multimeter.
2. Access — Remove the electrical/control service panel.
3. Document — Photograph every line, load, and 24V coil wire before disconnecting.
4. Remove — Transfer wires one at a time or label them, then unbolt the old contactor from the bracket.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo, confirming line/load and coil terminals.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and condenser fan energize.
