Overview
The Tempstar 1172472 contactor is a 1-pole, 30-amp definite purpose contactor with a 24-volt coil and built-in shunt, used to switch line power to the compressor and condenser fan in your Tempstar T4A430GKB200 condensing unit. When the thermostat calls for cooling, the 24V control signal energizes the coil, pulling the contacts closed to send 240V to the outdoor components. Contactors are among the most common HVAC failure points: the contacts pit, burn, and weld from arcing on every cycle, and the coil can fail open. Symptoms include a unit that won't start, buzzing or chattering at the contactor, contacts that stick closed so the unit never shuts off, or insects and debris fouling the contacts. Replacing it with the correct OEM 1-pole 30A unit restores reliable switching and protects the compressor.

Compatibility
This OEM contactor is factory-specified for the Tempstar T4A430GKB200 air conditioner and other ICP-family units (Heil, Comfortmaker, Tempstar) that call out part number 1172472. Verify pole count, amp rating, and 24V coil against your existing contactor before ordering.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and verify zero voltage across all terminals with a multimeter.
- Access — Remove the condenser service/electrical panel to expose the contactor.
- Document — Photograph every line, load, and 24V coil wire before disconnecting.
- Remove — Transfer wires one at a time, or label them, then unbolt the old contactor from its bracket.
- Install — Mount the new contactor, reconnect line, load, and 24V coil leads exactly per your photo.
- Test — Restore power, call for cooling, and confirm the contacts pull in cleanly with no chatter and the unit runs normally.
Signs You Need a Replacement
- Unit won't start even though the thermostat is calling for cooling.
- Loud buzzing, humming, or chattering from the contactor.
- Contacts visibly pitted, burnt, or melted, or stuck closed so the unit runs continuously.
- Intermittent cooling that improves when you tap the contactor.
