Overview
This is a genuine OEM 1-pole, 30 amp contactor with a 24V coil and integral shunt (part number 1172472) for the ICP WPA4244000RKA1 system. The contactor is the high-voltage switch that powers the compressor and condenser fan. When the thermostat sends a 24V call, the coil energizes and pulls the contacts closed, sending line voltage to the outdoor unit; when the call ends, the contacts open and shut the unit down. The shunt provides the return path on the unswitched leg. Contactors wear out from millions of make-and-break cycles — the contacts pit, burn, weld shut, or fail to close, and the coil can burn open. A failed contactor is one of the most common no-cool service calls.

Compatibility
This 1-pole 30A 24V contactor is the factory-specified replacement for the ICP WPA4244000RKA1 and its Tempstar, Heil, and Comfortmaker equivalents. The same 1-pole 30A/24V configuration is shared across many ICP WPA-series condensing units — verify the pole count, amp rating, coil voltage, and shunt arrangement against your original before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage at the contactor with a multimeter.
- Access — Remove the condensing unit's electrical access panel to expose the contactor.
- Document — Photograph every line, load, coil, and shunt connection before disconnecting.
- Remove — Disconnect all wires, unscrew the old contactor from the mounting base, and lift it out.
- Install — Mount the new contactor, then reconnect the line, load, 24V coil, and shunt leads exactly per your photo.
- Test — Restore power, send a cooling call, and confirm the contactor pulls in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Outdoor unit will not start on a cooling call
- Loud buzzing or chattering from the contactor
