Overview
This is the genuine OEM 2-pole, 30-amp definite purpose contactor with a 24-volt coil (part 1178074) for the ICP / Tempstar / Heil RGS101LFAB0AAAA system. The contactor is the high-voltage switch that energizes the compressor and condenser fan whenever the thermostat calls and the 24V control coil pulls the contacts closed. Over time the silver contacts pit, burn, and weld from the constant arcing of inrush current, and the coil can fail open — leaving the outdoor unit dead or chattering. A new 30A 2-pole contactor restores clean, reliable switching and protects the more expensive compressor and motor downstream.

Installation Guide
- Safety First — Disconnect power at the unit disconnect and breaker, then verify zero voltage across the contactor with a multimeter.
- Access — Remove the electrical-compartment service panel.
- Document — Photograph every line, load, and coil wire before disconnecting.
- Remove — Move wires one at a time to the new contactor, or unscrew the old contactor and transfer leads to matching terminals (L1/L2, T1/T2, and the 24V coil).
- Install — Mount the new contactor, confirm all terminals are torqued, and verify wiring against your photo.
- Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan energize.
Signs You Need a Replacement
- Outdoor unit hums or chatters but won't start.
- Burned, pitted, or welded contacts visible on inspection.
- Compressor and fan run continuously even with no call (stuck contacts).
