ICP 2-Pole 30A 24V Contactor for RGS303STEA0AAAA | Ships Today

Overview

This is a genuine OEM 2-pole, 30-amp contactor with a 24-volt coil (part number 1171554) for the ICP / Heil / Tempstar RGS303STEA0AAAA system. The contactor is the heavy-duty switch that energizes line-voltage loads when the 24V control circuit calls for operation. When the coil is energized it pulls in both poles to pass current; when the call ends the contacts spring open. Contactors are a high-wear item because the contacts arc every time they open and close, eventually pitting, welding, or refusing to pull in. Symptoms of a failing 30A contactor include a loud hum or buzz, contacts that stick closed so the load never shuts off, and a system that will not start because the contacts no longer close.

Specifications

Compatibility

Direct OEM replacement for the ICP / Heil / Tempstar RGS303STEA0AAAA. A 2-pole 30A 24V contactor is a common rating across many ICP-family units — confirm pole count, amp rating, and coil voltage against the contactor you are replacing 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 electrical service panel.
3. Document — Photograph all line, load, and 24V coil wiring before disconnecting.
4. Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its bracket.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power, place a call, and confirm both poles pull in cleanly with no chatter.

Signs You Need a Replacement

• Loud humming, buzzing, or chattering from the contactor
• System runs continuously because contacts are welded closed
