Overview
This is the genuine OEM 1-pole definite purpose contactor (Part No. 1172472) for the Tempstar T2H330GKD100 heat pump condensing unit. Rated for 30 amps with a 24-volt control coil and a built-in shunt, the contactor is the high-voltage switch that energizes the compressor and outdoor fan motor whenever the thermostat calls for cooling or heating. When the low-voltage coil receives 24V from the control board, the electromagnet pulls the contacts closed and passes line voltage to the compressor. A failed contactor is one of the most common no-cool/no-heat service calls — symptoms include a humming outdoor unit that will not start, pitted or welded contacts that keep the compressor running, chattering, or burnt terminals.

Compatibility
Engineered as the factory-correct replacement for the Tempstar T2H330GKD100 heat pump. The same 30A 24V single-pole platform is used across many ICP-family condensers and heat pumps sold under Heil, Comfortmaker, Arcoaire and Keeprite brands. Always confirm your existing contactor's amp rating, pole count and coil voltage before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker. Verify zero voltage at the line terminals with a multimeter before touching any wiring.
- Access — Remove the condenser unit's electrical access panel.
- Document — Photograph every wire and terminal position before disconnecting anything.
- Remove — Label and disconnect the line, load and 24V coil wires, then unscrew the old contactor from the bracket.
- Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the coil leads land on the 24V terminals.
- Test — Restore power, call for cooling, and verify the contacts pull in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Outdoor unit hums but the compressor will not start
- Pitted, burnt or welded contacts (unit keeps running with no call)
- Audible chattering or buzzing from the contactor
- Coil does not pull the contacts in when 24V is applied
