Overview
This is a genuine OEM 2-pole definite purpose contactor (part number 1178074) for the ICP / Tempstar / Heil RGS120STAB0AAA furnace and condensing unit. Rated for 30 amps per pole with a 24-volt control coil, the contactor is the electrically-controlled switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the low-voltage coil is energized, the contacts close and pass line voltage to the load; when the call ends, the spring-loaded contacts open. A failing contactor is one of the most common HVAC service calls — pitted, burned, or welded contacts cause hard starts, chattering, buzzing, or a unit that simply will not run.

Compatibility
Engineered as the factory replacement for the ICP / Tempstar / Heil RGS120STAB0AAA. The 2-pole 30A 24V configuration is also common across many residential condensing units and gas furnaces using a 24V control circuit. Always confirm pole count, amp rating, and coil voltage against the contactor you are removing.
Installation Guide
- Safety First – Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter before touching any terminal.
- Access – Remove the service/electrical panel to expose the contactor.
- Document – Photograph all line, load, and 24V coil wires before disconnecting anything.
- Remove – Disconnect each wire, release the mounting screws or clip, and lift out the old contactor.
- Install – Mount the new contactor, then reconnect each wire exactly per your photo (line in, load out, 24V to the coil terminals).
- Test – Restore power and call for cooling; confirm the contacts pull in cleanly and the unit starts without chatter.
Signs You Need a Replacement
- Loud buzzing, humming, or chattering from the contactor.
- Burned, pitted, or melted contacts (visible discoloration).
- Compressor or condenser fan won't start on a cooling call.
- Contacts welded closed so the unit runs continuously.
