Overview
This is a genuine OEM single-pole definite purpose contactor (part #1172472) for the ICP/Tempstar/Heil WCA3242GKR2 condensing unit. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V control coil is energized, it pulls in the contacts to deliver line voltage to the outdoor unit; when the call ends, the contacts open. This part is rated 30 amps with a 24V coil and includes an integrated shunt. Common failure symptoms include a buzzing or chattering outdoor unit, contacts that weld closed (the AC runs constantly), pitted or burned contacts, or a unit that simply will not start even though the thermostat is calling for cool.

Compatibility
Engineered as a direct OEM replacement for the ICP/Tempstar/Heil WCA3242GKR2 air conditioning condensing unit. This 1172472 contactor is also used across many ICP-family residential split-system condensers and heat pumps that specify a 1-pole, 30A, 24V coil contactor. Always confirm the part number on your existing contactor before ordering.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage at the contactor terminals with a multimeter.
- Access — Remove the condenser service panel to expose the contactor.
- 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 the bracket.
- Install — Mount the new contactor, reconnect each wire exactly per your photo, and confirm the 24V coil leads are landed correctly.
- Test — Restore power and trigger a cooling call; verify the contactor pulls in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Loud buzzing, humming, or chattering from the outdoor unit.
- Visibly pitted, burned, or melted contacts.
- Compressor runs continuously because the contacts have welded shut.
- Outdoor unit won't start despite a valid cooling call and good 24V signal.
