Overview
This is a genuine OEM 2-pole definite-purpose contactor (Part No. 1178211) rated at 40 amps with a 24-volt coil, designed for the ICP / Tempstar / Heil RGS091HFCA0AAA gas furnace and matched condensing systems. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V coil is energized, the contactor pulls in and closes both power poles, sending line voltage to the outdoor unit. A failed contactor is one of the most common reasons an outdoor unit won't start, hums but won't engage, or runs continuously. Pitted or welded contacts, a burned-out coil, or stuck points all point to replacement.

Compatibility
Engineered for the ICP Tempstar Heil RGS091HFCA0AAA furnace and the cooling equipment it controls. This 40A 24V 2-pole format is a standard definite-purpose footprint used across many ICP-family condensing units; always confirm amp rating, pole count, and coil voltage against the part you are removing.
Installation Guide
- Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter across the contactor terminals.
- Access — Remove the service panel from the unit to expose the electrical compartment.
- Document — Photograph every wire and terminal location before disconnecting anything.
- Remove — Label and disconnect the line, load, and 24V coil wires, then unscrew the old contactor from its mounting bracket.
- Install — Mount the new contactor, reconnect all wires exactly per your photo, and confirm tight, seated spade connections.
- Test — Restore power, run a cooling call, and verify the contactor pulls in cleanly and the unit starts.
Signs You Need a Replacement
- Outdoor unit hums but compressor and fan won't start
- Visibly burned, pitted, or welded contact points
- Buzzing or chattering when the thermostat calls for cooling
