Overview
This OEM 2-pole contactor (OEM part #1178074) is the electromagnetic switch that energizes the high-voltage load circuit in your ICP RGS102LSBA0AAA system. Rated at 30 amps with a 24V control coil, it uses a low-voltage signal from the control board to pull in two sets of line-voltage contacts. Contactors are a high-wear component: every call for operation slams the contacts closed, so over thousands of cycles the contact faces pit, burn, and weld. Common failure symptoms include a buzzing or chattering contactor, contacts that stick closed (unit won't shut off), or contacts that won't pull in at all (unit won't start). Replacing a worn contactor restores reliable switching and protects downstream components from arcing damage.

Compatibility
Directly fits the ICP/Heil/Tempstar RGS102LSBA0AAA. The 2-pole, 30A, 24V-coil configuration is also a common service part across many ICP-family condensing units and air handlers — always confirm amperage, pole count, and coil voltage against the contactor currently installed before ordering.
Installation Guide
- Safety First — Disconnect power at the breaker and pull the local disconnect. Verify zero voltage at the contactor terminals with a multimeter.
- Access — Remove the unit's electrical service panel.
- Document — Photograph every wire and terminal location before disconnecting anything.
- Remove — Label and disconnect the line, load, and 24V coil leads; unscrew the contactor from its mounting bracket.
- Install — Mount the new contactor and reconnect each wire exactly as photographed.
- Test — Restore power and confirm the contactor pulls in cleanly with no buzzing and that the unit cycles normally.
Signs You Need a Replacement
- Loud buzzing, humming, or chattering from the contactor
- Pitted, blackened, or welded contact points
- Unit won't start, or won't shut off after the call ends
- Visible arcing or a burnt-electrical smell at the contactor
