Overview
This is a genuine OEM 1-pole, 30-amp definite purpose contactor (OEM part #1172472) with an integrated shunt, built for the ICP/Tempstar/Heil WPA3364000RKC1 condensing unit. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the 24-volt control circuit calls for cooling. When the thermostat closes, 24V is applied to the coil, the magnetic field pulls the armature in, and line voltage passes through the contacts to the load. The built-in shunt provides a continuous current path that keeps the crankcase heater and control circuit energized while the contactor is open. Pitted, burned, or chattering contacts are one of the most common causes of a compressor that hums but won't start, or a condenser fan that runs intermittently. Replacing a worn contactor restores reliable, low-resistance switching and protects the more expensive compressor downstream.

Compatibility
Engineered as the factory replacement contactor for the ICP/Tempstar/Heil model WPA3364000RKC1 split-system condensing unit. The same definite-purpose footprint is used across many ICP-family air conditioners and heat pumps that share a 24V control circuit. Always confirm the OEM part number 1172472 and the 1-pole / 30A / 24V coil rating against the unit you are servicing 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 before touching any wiring.
- Access — Remove the condensing unit's electrical access panel.
- Document — Photograph all line, load, and 24V coil connections before disconnecting anything.
- Remove — Note shunt placement, transfer the wires off the old contactor one at a time, and unbolt it from the bracket.
- Install — Mount the new 1172472 contactor, reconnect line, load, and 24V coil leads exactly per your photo, and confirm the shunt is positioned correctly.
- Test — Restore power, call for cooling, and verify the contactor pulls in cleanly with the compressor and condenser fan energizing.
Signs You Need a Replacement
- Compressor hums or buzzes but will not start when cooling is called
- Burned, pitted, or welded contacts visible on inspection
- Audible chattering or buzzing from the contactor
- Condenser fan and compressor cycle intermittently or fail to energize
