Overview
This is a genuine OEM 2-pole definite purpose contactor for the ICP / Tempstar / Heil RGS101HFCA0AAA gas furnace and its companion condensing unit. The contactor is an electrically controlled switch that uses a 24V coil to close two sets of line-voltage contacts, energizing the compressor and condenser fan when the thermostat calls for cooling. Two amperage ratings are available for this model: a 30A version (OEM 1178074) and a 40A version (OEM 1178211). When a contactor fails, the most common symptoms are pitted or welded contacts that keep the compressor running continuously, a chattering or buzzing coil, or a unit that will not start at all because the contacts never close. Replacing a worn contactor restores reliable switching and protects the more expensive compressor from low-voltage and short-cycling damage.

Compatibility
Designed as a direct OEM fit for the ICP, Tempstar, Heil, and Comfortmaker RGS101HFCA0AAA system. Verify your existing contactor's pole count, amp rating, and 24V coil before ordering. Match 30A to 30A and 40A to 40A for the closest replacement.
Installation Guide
- Safety First — Disconnect power at the breaker and the unit disconnect, then verify zero voltage with a multimeter.
- Access — Remove the service panel to expose the contactor and control wiring.
- Document — Photograph all line and low-voltage wires before disconnecting.
- Remove — Label and disconnect each wire, unscrew the old contactor from the bracket, and lift it out.
- Install — Mount the new contactor, reconnect every wire to match your photo, and confirm the 24V coil leads are seated.
- Test — Restore power and watch the contacts pull in cleanly on a cooling call.
Signs You Need a Replacement
- Visible pitting, burning, or welding on the contacts.
