Overview
This is an OEM single-pole definite purpose contactor (part #1172472) for the ICP / Tempstar / Heil WTH3242000RKA1 heat pump. Rated for 30 amps with a 24-volt control coil and an integrated shunt, this contactor is the electromechanical switch that energizes the outdoor compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. When the 24V coil is energized, the contacts close and pass line voltage to the compressor; when the call ends, the spring-loaded contacts open and shut the unit down. Over thousands of cycles the contact points pit, burn, and weld from arcing, and the coil can fail open or short. A failing contactor is one of the most common reasons an outdoor unit hums, chatters, fails to start, or will not shut off.

Compatibility
Engineered as the direct OEM replacement for the ICP / Tempstar / Heil WTH3242000RKA1 heat pump. The 30A / 24V / 1-pole configuration is also common across many comparable ICP-family condensing units and heat pumps — always confirm amperage, coil voltage, and pole count against your existing contactor before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the outdoor unit's electrical service 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 and reconnect every wire exactly per your photo.
- Test — Restore power and confirm the contactor pulls in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Outdoor unit hums or buzzes but the compressor will not start.
- Burned, pitted, or melted contact points visible on the old part.
