Overview

This OEM control board kit (part 1183618) is the integrated ignition control that runs the entire sequence of operation on the ICP RGS091LSCB0AAA gas furnace. It manages the inducer, hot surface igniter, gas valve timing, flame sensing, and blower on/off delays, while monitoring the pressure switch and limit safeties. When the board fails, the furnace may not respond to the thermostat, lock out after ignition, run the blower continuously, or throw erratic fault codes on its diagnostic LED. Because the board interprets every safety input, a failing board is a common cause of intermittent no-heat calls that seem to come and go.

Frequently Asked Questions

Does this Control Board fit my ICP RGS091LSCB0AAA — Integrated Ignition Control | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS091LSCB0AAA — Integrated Ignition Control | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the control board on my ICP RGS091LSCB0AAA — Integrated Ignition Control | Ships Today?

Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.

My HVAC system is completely dead. What could be wrong?

Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.

Is this control board compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP control board?

OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.

How fast does National HVAC Parts ship?
