Overview
This is the genuine OEM definite-purpose contactor (part number 1172472) for the ICP / Tempstar / Heil WCA3304GKA2 condensing unit. A contactor is the electrically-controlled switch that powers your outdoor unit's compressor and condenser fan motor. When the thermostat calls for cooling, the 24-volt control circuit energizes the contactor coil, pulling the contacts closed to send line voltage to the compressor. This is a 1-pole, 30-amp unit with a 24V coil and an integrated shunt. As the contact points pit, arc, and burn over years of cycling, you'll see a humming unit that won't start, intermittent cooling, or a compressor that trips the breaker. Replacing a worn contactor is one of the most common and affordable HVAC repairs.

Compatibility
This contactor is the factory replacement for the ICP-family WCA3304GKA2 condensing unit and the many Tempstar, Heil, and Comfortmaker units built on the same platform that originally shipped with OEM part 1172472. Confirm your existing contactor is a 1-pole, 30A, 24V-coil unit before ordering.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage across the line terminals with a multimeter.
- Access — Remove the condenser service panel to expose the electrical compartment.
- Document — Photograph every wire on the old contactor 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 and reconnect every wire exactly per your photo, confirming the 24V coil leads are correct.
- Test — Restore power, call for cooling, and verify the contacts pull in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Outdoor unit hums but the compressor and fan won't start.
- Visible pitting, burning, or melted plastic on the contact points.
- Intermittent cooling or contacts that chatter and buzz.
- Contacts that weld closed, leaving the unit running constantly.
