Overview
This OEM contactor is the electromechanical switch that energizes the high-voltage components in your ICP RGS300HFFA0AAAA system. When the 24V control circuit calls, the coil pulls the contacts closed and passes line voltage to the load. Two factory-spec options cover this model: part 1171554 is a 2-pole 30-amp contactor with a 24V coil, and part 1183142 is a 3-pole 60-amp contactor with a 24V coil. A failing contactor is one of the most common HVAC service calls — symptoms include a chattering or buzzing hum, pitted or welded contacts, a unit that won't start, or one that won't shut off because the contacts have fused closed.

Compatibility
Engineered as a direct OEM replacement for the ICP / Tempstar / Heil RGS300HFFA0AAAA and shares specs with many other ICP-family condensing units and air handlers that use a 24V-coil definite-purpose contactor. Match the pole count and amp rating to the part you are removing.
Installation Guide
- Safety First — Disconnect power at the breaker and pull the service disconnect. Verify zero voltage with a multimeter before touching any terminal.
- Access — Remove the service panel to expose the control compartment.
- Document — Photograph every wire and terminal before disconnecting anything.
- Remove — Label and remove the line, load, and 24V coil leads, then unscrew the old contactor from the bracket.
- Install — Mount the new contactor, transfer the wires one at a time per your photo, and confirm the coil leads land on the 24V terminals.
- Test — Restore power and confirm the contactor pulls in cleanly with no chatter when the system calls.
Signs You Need a Replacement
- Loud buzzing, humming, or chattering at the contactor.
- Burned, pitted, or welded contacts.
- System fails to start even with a confirmed 24V signal at the coil.
- Unit will not shut off because the contacts are stuck closed.
