Overview
This is a genuine OEM 2-pole definite purpose contactor for the ICP (International Comfort Products) RHS090L0AA0AAAA heat pump system, covering OEM part numbers 1178074 (2-pole, 30A) and 1178211 (2-pole, 40A). The contactor is the high-voltage switch that energizes your compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump heating. A low-voltage 24V signal pulls in the coil, closing the line-voltage contacts. Over thousands of cycles the contacts pit, burn, and weld, and the coil weakens — leading to a compressor that won't start, chattering relays, or a unit that runs continuously and won't shut off. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs.

Compatibility

Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter at the contactor terminals.
- Access — Remove the condenser service panel.
- Document — Photograph every wire and terminal position before disconnecting anything.
- Remove — Note line, load, and 24V coil leads, then transfer wires one at a time to the new contactor, or unscrew the old unit 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 on a cooling call and that the compressor and fan energize.
Signs You Need a Replacement
- Compressor or condenser fan won't start, or only starts when you tap the contactor.
- Loud buzzing, humming, or chattering from the contactor.
- Visibly burnt, pitted, or melted contacts.
- Unit runs nonstop and won't shut off (welded contacts).
