Overview
This OEM ICP definite-purpose contactor (part number 1178074) is the electrical switch that energizes the compressor and condenser fan motor in your RHS048L0XA0AAAA heat pump. It is a 2-pole, 30-amp device with a 24-volt coil. When the thermostat calls for cooling or heating, the low-voltage 24V signal pulls the contactor's armature in, closing the line-voltage contacts and starting the outdoor unit. Over years of service the silver contacts pit, burn, and weld from arcing, while ants and debris can jam the plunger. A failing contactor causes hard starts, chattering, buzzing, an outdoor unit that won't shut off, or one that won't start at all.

Compatibility
Engineered as the factory replacement for the ICP RHS048L0XA0AAAA and shared across the RHS048 family of ICP, Heil, Tempstar, and Comfortmaker condensing units and heat pumps that use a 2-pole 30A, 24V contactor. Always confirm pole count, amp rating, and coil voltage against the part you are removing before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the contactor terminals.
- Access — Remove the condensing unit's electrical access panel.
- Document — Photograph every wire and terminal position before disconnecting anything.
- Remove — Label and pull the line, load, and 24V coil wires, then unscrew the old contactor from the bracket.
- Install — Mount the new contactor and reconnect each wire exactly per your photo, confirming the 24V coil leads land on the coil terminals.
- Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start without chatter.
Signs You Need a Replacement
- Loud buzzing, humming, or chattering from the outdoor unit when it starts.
- Burned, pitted, or welded contacts visible on the old part.
- Compressor and fan won't start even though the thermostat is calling.
- Outdoor unit runs continuously and won't shut off when satisfied.
