Overview

This is a genuine OEM 2-pole definite purpose contactor (part number 1178211) for the ICP / Tempstar / Heil RGS091HFCB0AAA furnace. The contactor is an electrically controlled switch that closes the line-voltage circuit to the compressor and condenser fan motor whenever the 24V control circuit energizes its coil. Rated for 40 amps with a 24-volt coil, it carries the high current load every time the system calls for cooling. Over thousands of cycles the silver-alloy contacts pit, burn, and weld; a failed contactor is one of the most common causes of a no-cool condition. Typical failure symptoms include a humming or chattering relay, the outdoor unit failing to start, contacts that stick closed so the compressor never shuts off, or visible arcing and pitting on the contact pads.

Access — Remove the electrical access panel on the unit.
Document — Photograph all wire connections before disconnecting anything.
Remove — Label and transfer wires one at a time, then unscrew the old contactor from its bracket.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the 24V coil leads are landed.
Test — Restore power, call for cooling, and verify the contactor pulls in cleanly with no chatter.
