Overview
This is a genuine OEM 2-pole definite purpose contactor (Part No. 1178074) for the ICP/Heil/Tempstar RGS102LTAB0AAA gas furnace and its matched condensing unit. The contactor is the electrically operated switch that closes the high-voltage line circuit to the compressor and condenser fan motor whenever the 24V control circuit calls for cooling. It is rated for 30 amps per pole with a 24V coil. When the coil energizes, both poles pull in simultaneously and pass line voltage to the load. Failure symptoms include a system that won't start, chattering or buzzing at the contactor, pitted or welded contacts, or an outdoor unit that runs continuously because the contacts have fused closed. A contactor with burned or carbon-tracked contacts should be replaced rather than cleaned.

Compatibility
Designed as the factory replacement for the ICP/Heil/Tempstar RGS102LTAB0AAA. As a 2-pole 30A 24V definite purpose contactor it also serves as a direct functional replacement across many comparable Carrier-family residential split systems using the same coil and contact ratings. Confirm pole count, amp rating, and coil voltage against your existing part before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter at the contactor line terminals.
- Access — Remove the service panel from the unit.
- Document — Photograph every wire and terminal before disconnecting anything.
- Remove — Note line, load, and 24V coil leads, then transfer wires one at a time to the new contactor. Unscrew the old contactor from the bracket.
- Install — Mount the new contactor and reconnect each lead per your photo, confirming the 24V coil terminals are correct.
- Test — Restore power, call for cooling, and verify both poles pull in and the compressor and fan energize.
Signs You Need a Replacement
- Loud buzzing or chattering from the contactor when cooling is called.
- Pitted, blackened, or welded contacts.
- Outdoor unit runs nonstop because contacts are stuck closed.
- System fails to start even though the thermostat is calling.
