ICP 2-Pole 30A Contactor for RGS181LFAA0AGAA — 24V Coil | Ships Today

Overview

This genuine OEM 2-pole 30-amp contactor with a 24V coil (Part Number 1171554) is the heavy-duty switch that energizes line-voltage loads in ICP, Heil, Tempstar, and Comfortmaker equipment paired with the RGS181LFAA0AGAA. When the control board sends 24 volts to the coil, the magnetic armature pulls in and both poles close, sending power to the connected load. Contactors wear out from millions of switching cycles — contacts pit, burn, or weld, and coils fail open. A failing contactor is a leading cause of no-cool / no-heat calls.

Specifications

Compatibility

Direct-fit replacement for the ICP/Tempstar/Heil RGS181LFAA0AGAA and other units originally equipped with the 2-pole 30A 24V-coil contactor 1171554. Confirm pole count, amp rating, and coil voltage against your existing part before ordering.

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 to expose the contactor.
3. Document — Photograph every line, load, and coil wire before disconnecting.
4. Remove — Transfer wires one at a time, then unscrew the old contactor from the mounting base.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo.
6. Test — Restore power and confirm the contactor pulls in cleanly on a call with no chatter.

Signs You Need a Replacement

• Pitted, burned, or welded contacts that stick closed.
• System won't energize even with 24V present at the coil.
