Overview
This is a genuine OEM 2-pole definite-purpose contactor for the ICP / Tempstar / Heil RGS150LFAA0AKAA gas furnace and packaged unit. The contactor is the electrically operated switch that closes the line-voltage circuit to the blower or compressor when the 24V control circuit calls. When the thermostat or control board energizes the 24-volt coil, the magnetic armature pulls the contacts closed and power flows to the load; when the call ends, a spring opens the contacts. This listing covers OEM part numbers 1178074 (2-pole, 30A, 24V) and 1178211 (2-pole, 40A, 24V) so you can match the exact amperage your unit was built with. Common failure symptoms include a unit that won't start, chattering or buzzing at the contactor, pitted or welded contacts, or a humming coil that never pulls in.

Compatibility
Designed as the factory replacement for ICP family equipment including the RGS150LFAA0AKAA, and shared across many Tempstar, Heil, Comfortmaker, and Day & Night models that use a 2-pole 24V-coil contactor. Always confirm the amperage and coil voltage stamped on your existing contactor 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 contactor.
- Document — Photograph every wire and its terminal before disconnecting anything.
- Remove — Label and pull the line, load, and 24V coil wires, then unbolt the old contactor from the bracket.
- Install — Mount the new contactor and reconnect each wire exactly per your photo.
- Test — Restore power and confirm the contactor pulls in cleanly on a call with no chatter.
