Overview
This OEM single-pole definite purpose contactor (part #1173690) is the electrical switch that energizes the compressor and condenser fan motor in your ICP WPG3482115RKB1 system. Rated for 40 amps with a 24-volt control coil, it closes when the thermostat calls for cooling, sending line voltage to the outdoor unit. Contactors are one of the most common failure points in HVAC equipment because their contacts arc and pit every time they open and close. Symptoms of a failing contactor include a humming or chattering outdoor unit, contacts welded shut so the compressor never shuts off, or burned/pitted contacts that prevent the unit from starting at all.

Compatibility
This contactor is the factory-specified switch for the ICP WPG3482115RKB1 and is shared across many Heil, Tempstar, Comfortmaker, and Carrier-built condensing units that use a 40A 24V single-pole contactor. Always confirm your existing contactor's amp and coil voltage rating before ordering.
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 all wire connections before disconnecting anything.
- Remove — Label and disconnect the line, load, and 24V coil wires, then unscrew the old contactor from its bracket.
- Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the 24V coil leads are secure.
- Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Outdoor unit hums or buzzes but the compressor won't start.
- Visible pitting, burning, or melted plastic on the contacts.
- Unit runs constantly because contacts are welded closed.
- Chattering or rapid clicking when the thermostat calls for cooling.
