Overview
This is a genuine OEM single-pole 30-amp contactor with a 24V coil and shunt (part number 1172472) for the Tempstar T2H324GKA100 heat pump. The contactor is the electrically-controlled switch that sends line voltage to the compressor and condenser fan motor whenever the thermostat calls. Its 24V coil pulls the contacts closed; the built-in shunt maintains the proper circuit path. Contactors are a high-wear part — the contacts pit and burn over thousands of cycles, eventually causing a no-start or chattering condition.

Compatibility
A direct-fit replacement for the Tempstar T2H324GKA100 heat pump and equivalent ICP-family condensing units originally equipped with contactor 1172472. As a 1-pole 30A 24V-coil contactor with shunt, it also serves as a common service replacement across comparable Heil, Comfortmaker, and ICP outdoor units. Confirm coil voltage (24V), amp rating (30A), and pole count before ordering.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter across the contactor terminals.
- Access — Remove the outdoor unit's electrical access panel.
- Document — Photograph all line, load, and 24V coil wire positions before disconnecting.
- Remove — Transfer wires one at a time or label them, then unscrew the old contactor from its bracket.
- Install — Mount the new 1172472 contactor and reconnect each wire to the matching terminal per your photos.
- Test — Restore power, call for cooling/heating, and confirm the contactor pulls in cleanly and the compressor and fan energize.
Signs You Need a Replacement
