Overview
This is a genuine OEM 2-pole definite-purpose contactor for the ICP / Tempstar / Heil RGS101HEAB0AAAA gas furnace and packaged system. The contactor is the electromagnetic switch that energizes the compressor and condenser fan motor whenever the 24-volt control circuit calls for cooling or heat-pump operation. Its low-voltage coil pulls in two sets of line-voltage contacts, letting a small thermostat signal safely switch high-current loads. Available in both 30-amp (P/N 1178074) and 40-amp (P/N 1178211) ratings, each with a 24V coil. A failing contactor is one of the most common HVAC service calls — symptoms include a system that won't start, chattering or buzzing at the unit, pitted or welded contacts that keep the compressor running, or visible arcing and burnt terminals.

- Access — Remove the unit's electrical access panel.
- Document — Photograph all wire positions on both the line and load sides and the 24V coil terminals before disconnecting.
- Remove — Label and disconnect each wire, then unscrew the old contactor from its mounting base.
- Install — Mount the new contactor and reconnect every wire exactly as photographed, ensuring tight terminal connections.
- Test — Restore power and confirm the contactor pulls in cleanly on a cooling/heat call with no chatter.
