Overview
This genuine OEM 2-pole 30-amp contactor with a 24V coil (part number 1178074) is the primary switching relay for the ICP / Tempstar / Heil RGS180LFEA0AAAA unit. The contactor handles the high-current line voltage that powers the compressor and/or condenser fan motor. When the thermostat calls and the 24V coil energizes, an electromagnet pulls the two main contacts closed, sending line power to the load; when the call ends, the contacts open and cut power. Rated for 30 amps across both poles, it is built to handle the inrush and continuous current of the equipment it serves. Contactors are wear items — their contacts arc and erode with every cycle. A failing contactor causes hard starting, buzzing, chattering, contacts that weld shut (leaving the unit running nonstop), or contacts that won't close at all, leaving the system dead on a call for cooling.

Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the unit's electrical service panel.
- Document — Photograph all line, load, and 24V coil wire positions before disconnecting.
- Remove — Transfer wires one at a time or label them, unfasten the old contactor, and lift it out.
- Install — Mount the new contactor and reconnect each wire exactly per your photos.
- Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the load energizes.
Signs You Need a Replacement
- Loud buzzing, humming, or chattering from the contactor
- Pitted, burned, or welded contacts
