Overview
This is a genuine OEM 2-pole definite purpose contactor (part number 1178074) for the ICP/Tempstar/Heil RGS150LFAA0AAAA gas furnace condensing unit. The contactor is the electrically-operated switch that energizes the compressor and condenser fan motor when the thermostat calls for cooling. Its 24-volt coil is pulled in by the low-voltage control circuit, closing two sets of 30-amp line-voltage contacts to deliver power to the load. A failing contactor is one of the most common no-cool service calls: pitted or welded contacts cause the unit to short-cycle, chatter, or fail to start, while a burned-out coil leaves the system completely dead on a cooling call.

Compatibility
Engineered as the factory replacement for ICP model RGS150LFAA0AAAA and shared platform units sold under the Tempstar, Heil, Comfortmaker, Arcoaire and KeepRite brands. Always confirm the existing contactor is a 2-pole 30A unit with a 24V coil before installing.
Installation Guide
- Safety First - Disconnect power at the unit disconnect and breaker, then verify zero voltage at the contactor line terminals with a multimeter.
- Access - Remove the control-access service panel from the condensing unit.
- Document - Photograph every line, load, and 24V coil wire before disconnecting anything.
- Remove - Label and disconnect the line, load, and coil leads, then unscrew the old contactor from the mounting bracket.
- Install - Mount the new contactor, reconnect each wire exactly per your photo, and confirm the coil terminals carry the 24V leads.
- Test - Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Buzzing, humming, or chattering from the contactor on a cooling call.
- Compressor and condenser fan will not start even though 24V is present at the coil.
- Visibly pitted, blackened, or welded contacts.
- Unit short-cycles or runs continuously because contacts stick closed.
