Overview
This OEM furnace control board kit (ICP part #1183618) is the integrated electronic control for your ICP/Tempstar/Heil RGS213HTEA0AAAA gas furnace. It governs the entire heating sequence — ignition timing, inducer and blower motor staging, gas valve control, and continuous monitoring of the limit and flame-sense safeties. A failed board commonly causes no-heat conditions, short-cycling, lockouts, a blower that runs nonstop, or a furnace that ignores the thermostat. Installing a genuine OEM board restores the exact timing and safety logic the furnace was designed to use.

- Access — Remove the blower-compartment service panel to expose the control board.
- Document — Photograph every harness, plug, and terminal position before disconnecting anything.
- Remove — Unplug all connectors, release the mounting standoffs/screws, and lift out the failed board.

- Test — Restore power, initiate a heat call, and confirm the full ignition sequence, blower operation, and proper shutdown.
