Overview
This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) brain of the ICP / Heil / Tempstar RGS150HSCA0AAAA furnace. The board sequences the entire heat cycle — it powers the inducer, energizes the hot surface igniter, opens the gas valve, monitors the flame sensor and limit/pressure safeties, and times the blower on and off. When the board fails, the furnace may be completely dead, lock out, run the blower continuously, or fail to ignite. The kit ships with the board and mounting/connector provisions so it drops into the existing harness. Installing a fresh OEM board restores correct, safe ignition sequencing and clears intermittent no-heat faults caused by failed relays or burnt traces.

- Access — Remove the blower/control compartment door.
- Document — Photograph every plug and wire on the board; note any DIP switch or jumper settings.
- Remove — Unplug each connector, release the board standoffs, and lift out the old board.
- Install — Mount the new board, match any DIP switch/jumper settings, and reconnect every plug per your photos.
- Test — Restore power, start a heat call, and confirm full sequence: inducer, igniter, flame, and timed blower operation.
