Overview
The contactor is the electrically operated switch that energizes the high-voltage circuit feeding your ICP RGS300HREA0AAAA system's blower, inducer, and condensing components whenever the 24-volt control circuit calls for operation. This OEM replacement covers both factory configurations for this model: the 2-pole 30-amp contactor (part 1171554) and the 3-pole 60-amp contactor (part 1183142), each driven by a 24V coil. A failing contactor is one of the most common no-start and short-cycle culprits in residential HVAC. Pitted, burned, or welded contacts cause chattering, intermittent operation, or contacts that stick closed and won't let the unit shut off; a burned-out coil prevents the contacts from pulling in at all, leaving the system dead on a call for heat or cool.

Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the line terminals with a multimeter.
- Access — Remove the control/electrical service panel.
- Document — Photograph every line and coil wire before disconnecting.
- Remove — Label and pull the line and load leads, disconnect the 24V coil wires, and unscrew the old contactor from its bracket.
- Install — Mount the new contactor, transfer wires terminal-for-terminal per your photo, and torque connections snug.
- Test — Restore power, initiate a call, and confirm the contactor pulls in cleanly with no chatter.
Signs You Need a Replacement
- Loud buzzing, humming, or chattering at the contactor on startup.
- Visible pitting, arcing scars, or melted contacts.
- System won't start, or won't shut off because contacts are welded closed.
- Intermittent operation that improves when you tap the contactor.
