Overview
These are genuine OEM 2-pole definite-purpose contactors for the ICP/Heil/Tempstar RHS090L0CB0AAA heat pump, available in the 30-amp version (part 1178074) and the 40-amp version (part 1178211), both with a 24-volt coil. The contactor is the high-voltage switch that powers the compressor and outdoor condenser fan motor. On a heating or cooling call, the 24V control circuit energizes the coil, pulling the contacts closed to start the unit. The amp rating must match your unit's factory contactor — confirm whether your equipment uses the 30A or 40A version before ordering. As the most common wear item in any condensing unit, a failed contactor causes no-cool/no-heat calls, buzzing or chattering, and welded or pitted contacts.

Compatibility
Built as the factory replacement for the ICP RHS090L0CB0AAA heat pump and the rest of the RHS090 family. Both the 30A and 40A 2-pole, 24V-coil versions service many other Heil, Tempstar, Comfortmaker, and ICP-built condensing units using the same coil voltage. Match the amp rating to your existing contactor — using a lower-rated contactor than the factory spec will shorten its life.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the line terminals with a multimeter.
- Access — Remove the condensing unit's electrical access panel.
- Document — Photograph every wire and terminal position before disconnecting.
- Remove — Transfer the line, load, and 24V coil leads one at a time, then unbolt the old contactor from its bracket.
- Install — Mount the matching-amp contactor and reconnect each wire to the correct terminal per your photo.
- Test — Restore power, place a call, and confirm the contactor pulls in cleanly and the compressor and fan run.
Signs You Need a Replacement
- Buzzing, humming, or chattering from the outdoor unit.
- Burned, pitted, or welded contacts stuck closed.
- Compressor and condenser fan won't start on a call.
- Visible arcing, melted housing, or insect/debris intrusion at the contacts.
