ICP 2-Pole 30A Contactor 24V Coil for RGS243SDAA0AAAA — Ships Today

Overview

This genuine OEM contactor (part number 1171554, "Contactor 2P 30A 24V") is the electrically operated switch that powers the major loads in your ICP RGS243SDAA0AAAA system. When the thermostat calls, the 24-volt coil energizes and pulls the contacts closed, sending line voltage to the motor and compressor circuit; when the call ends, the contacts open. With two poles, a 30-amp rating, and a 24V control coil, it handles the high inrush current of HVAC loads. Contactors fail from pitted, burned, or welded contacts and from worn coils that chatter or stop pulling in.

Specifications

Compatibility

Direct-fit replacement for the ICP RGS243SDAA0AAAA and other ICP-family (Tempstar, Heil, Comfortmaker) units specifying a 2-pole 30A 24V contactor. Verify pole count, amp rating, and coil voltage against your existing part before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter at the line terminals.
2. Access — Remove the service panel to expose the control compartment.
3. Document — Photograph every wire and terminal position before disconnecting.
4. Remove — Transfer wires one at a time, or label each lead, then unscrew the old contactor from its bracket.
5. Install — Mount the new contactor and reconnect line, load, and 24V coil wires exactly as photographed.
6. Test — Restore power, call for cooling/heating, and confirm the contacts pull in cleanly with no chatter.

Signs You Need a Replacement

• Buzzing or chattering when the system tries to start
• Burned, pitted, or melted contact points
• Contacts welded closed so the system won't shut off
• No response on a call even though 24V is present at the coil
