Overview
This OEM 40-amp, 2-pole definite purpose contactor (part number 1176763) is the exact replacement for your ICP Tempstar Heil RGX048KFCA0AAA system. A contactor is an electrically controlled switch that uses a low-voltage 24V signal from the control board to energize the high-voltage line that powers the blower, inducer, or condenser circuit. Each time a heat or cool call is made, the 24V coil pulls the contacts closed; when the call ends, the contacts open. Because the contacts arc every cycle, they slowly pit, burn, and weld over time. A failing contactor shows up as a system that won't start, a loud chattering or buzzing at the contactor, contacts that stick closed so equipment runs nonstop, or visible burn marks and melted housing. Rated for 40 amps with a 24-volt coil, this contactor restores clean, reliable switching to your equipment.

Compatibility
Designed as a direct-fit OEM replacement for the ICP Tempstar Heil RGX048KFCA0AAA. The same 40A 2-pole platform is used across many ICP-family gas furnaces and air handlers, but always confirm amperage, pole count, and 24V coil voltage against the part you are removing.
Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the service panel to expose the control compartment.
- Document — Photograph all wire positions before disconnecting anything.
- Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor from its bracket.
- Install — Mount the new contactor and reconnect each wire exactly as photographed.
- Test — Restore power and confirm the contacts pull in cleanly on a call with no chatter.
Signs You Need a Replacement
- Loud chattering or buzzing noise from the contactor on startup
- System fails to start or starts intermittently
