Overview
This OEM 2-pole definite-purpose contactor (OEM part 1178074) is the electromechanical switch that powers the major loads in your ICP RGS102HFAA0AAA system. Rated at 30 amps with a 24-volt coil, it energizes when the thermostat calls for cooling or heating, pulling its contacts closed to feed line voltage to the compressor and condenser fan motor. Contactors are high-wear items: their silver contacts arc every time they open and close, eventually pitting, welding, or burning. Common failure symptoms include a system that won't start, a humming or chattering contactor, contacts that stick closed (equipment runs constantly), or visible burning and melted housing. Replacing a worn contactor restores reliable switching and prevents damage to the more expensive compressor it protects.

Compatibility
Directly fits the ICP RGS102HFAA0AAA and the matching Tempstar, Heil, and Comfortmaker furnace and air-handler platforms that share this 2-pole 30A 24V control architecture. Always confirm the existing contactor's amp and coil rating against your unit before ordering.
Installation Guide
- Safety First — Disconnect power at the breaker and the unit disconnect, then verify zero voltage with a multimeter.
- Access — Remove the electrical service panel to expose the control box.
- Document — Photograph all wire positions before disconnecting anything.
- Remove — Note the line, load, and coil (24V) terminals, transfer one wire at a time, then unscrew the old contactor from its mount.
- Install — Mount the new contactor and reconnect each wire to the identical terminal per your photo.
- Test — Restore power and confirm the contactor pulls in cleanly and the equipment energizes.
Signs You Need a Replacement
- System fails to start or starts intermittently
