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 WPG3482115LKB1 system. Rated for 40 amps with a 24-volt control coil, it closes when the thermostat calls for cooling and sends line voltage to the outdoor unit. Because its contacts arc and pit with every cycle, the contactor is one of the most common HVAC failure points. A failing contactor can leave the outdoor unit humming or chattering, weld its contacts shut so the compressor never stops, or burn its contacts so the unit won't start at all.

Compatibility
This contactor is the factory-specified switch for the ICP WPG3482115LKB1 and is shared across many Heil, Tempstar, Comfortmaker, and Carrier-built condensing units that use a 40A 24V single-pole contactor. 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.
