Overview
This OEM single-pole 30-amp definite purpose contactor (part 1172472) is the line-voltage switch for the ICP / Tempstar / Heil WJA324000KTP0A2 unit. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed, sending line voltage to the compressor and condenser fan motor. The integrated shunt provides the correct internal jumper for this unit's wiring. Contactors are one of the most common failure points in an outdoor unit: the contacts pit, burn, and weld from constant arcing, and the coil can fail open so it no longer pulls in. Symptoms include a humming or chattering contactor, a unit that will not start, or contacts that stick closed and keep the compressor running.

Installation Guide
- Safety First – Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter across the line terminals.
- Access – Remove the condenser service panel.
- Document – Photograph every line-voltage and 24V coil wire before disconnecting anything.
- Remove – Transfer one wire at a time, or label leads, then unbolt the old contactor from its bracket.
- Install – Mount the new contactor, confirm the shunt is in place, and reconnect the line and 24V coil wires exactly per your photo.
- Test – Restore power and verify the coil pulls the contacts in on a cooling call and the compressor and fan start.

- Humming, buzzing, or chattering contactor that will not stay pulled in
- Pitted, burned, or welded contacts visible on inspection
