Overview
This OEM single-pole definite purpose contactor (part #1172472) is the electrical switch that powers the compressor and outdoor fan motor in your Tempstar T4H324GKA200 heat pump. When the thermostat calls for cooling or heating, the 24V control coil energizes and pulls the main contacts closed, sending line voltage to the condensing unit. This contactor is rated for 30 amps, uses a 24-volt coil, and includes a shunt for proper line-side connection. A failed contactor is one of the most common no-cool/no-heat service calls — symptoms include a unit that hums but won't start, pitted or welded contacts, chattering, or a complete failure to engage when the thermostat calls.

Compatibility
Engineered as the OEM replacement for the Tempstar T4H324GKA200 heat pump. The same 1-pole 30A/24V form factor is widely shared across ICP-family condensing units (Heil, Comfortmaker, Arcoaire, Keeprite). Always confirm coil voltage and amp rating against your existing part before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker; verify zero voltage at the contactor terminals with a multimeter.
- Access — Remove the condensing unit's electrical access panel.
- Document — Photograph every wire and terminal position before disconnecting anything.
- Remove — Note the line, load, and 24V coil leads, then transfer wires one at a time from the old contactor and unscrew it from the mounting bracket.
- Install — Mount the new contactor, then reconnect each wire to the matching terminal per your photo.
- Test — Restore power and call for cooling; confirm the contacts pull in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Outdoor unit hums or buzzes but the compressor won't start
- Burnt, pitted, or welded-together contacts
