Overview
This OEM control board kit (part number 1183618) is the brain of your ICP RGS213LFCA0AAAA packaged unit. The integrated furnace control manages the entire heating and cooling sequence — inducer and ignition timing, gas valve operation, blower on/off delays, and all safety interlocks including limit and pressure switch monitoring. When the board fails, the unit can lose heat entirely, stop responding to thermostat calls, or trip into hard lockout. Common failure symptoms include no response on a heat or cool call, blower running continuously or not at all, fault codes flashed on the diagnostic LED, and visible scorching or failed relays on the board itself.

Compatibility

- Document — Photograph every connector and wire harness position before unplugging.
- Remove — Unplug each harness, remove the mounting screws or standoffs, and lift out the old board.

- Test — Restore power and gas, then verify a full heat and cool sequence with correct blower timing.
