Overview
This is a genuine OEM single-pole contactor (part number 1172472) for the ICP / Tempstar / Heil WPG4304040RKA1 package unit. The contactor is the electromechanical switch that energizes the compressor and condenser fan motor whenever the 24V control circuit calls for cooling. Rated at 30 amps with a 24-volt coil and an integrated shunt, it handles the high-current load while being triggered by the low-voltage thermostat signal. Over time the contact points pit, burn, or weld from constant arcing — a failed contactor is one of the most common causes of an outdoor unit that hums but won't start, or one that runs continuously and won't shut off. Replacing it restores clean, reliable switching.

Compatibility
Designed as the factory replacement for the ICP WPG4304040RKA1 packaged system. The same 30A 24V single-pole contactor is used across many comparable ICP, Tempstar, Heil, and Comfortmaker condensing and package units — verify amp rating, pole count, and coil voltage against your existing part before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and the unit disconnect, then verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the service panel on the control side of the unit.
- Document — Photograph all wire connections to the contactor before disconnecting anything.
- Remove — Transfer wires one at a time to the new contactor, or label them; unscrew the old contactor from its bracket.
- Install — Mount the new contactor and reconnect line, load, and 24V coil wires exactly per your photo.
- Test — Restore power, call for cooling, and confirm the contactor pulls in and the compressor/fan energize.
