Overview
This genuine OEM control board kit (part number 1183618) is the factory ignition/integrated furnace control replacement for the ICP / Tempstar / Heil RGS240LDEA0AAAA gas/electric package unit. The control board is the brain of the system — it manages the ignition sequence, inducer and blower timing, flame sensing, safety lockouts, and limit/pressure switch monitoring. When the board fails you may see no heat, a blower that won't start or won't stop, a unit stuck in lockout, or erratic LED fault codes. Supplied as a complete kit with the correct connectors, this OEM board restores proper, code-correct operation without the guesswork of a universal control.

- Document — Photograph every plug, harness, and terminal on the old board before unplugging anything.
- Remove — Unplug each connector, release the mounting standoffs/screws, and lift out the old board.
- Install — Mount the new board on the same standoffs and reconnect every harness exactly per your photo.
- Test — Restore power and run a full heat and cool cycle, watching the diagnostic LED for normal operation and no fault codes.
