ICM Controls ICM2805A Furnace Control Board

This board is designed as a direct, cost-effective replacement for specific Nordyne furnace modules, including the G3, G4, G5, G6, M2, and M3 series. Before purchasing, verify your current module model number matches these specifications to ensure compatibility.

The microprocessor manages the timing and safety protocols of your furnace with higher precision than older analog boards. It accurately controls the gas valve, inducer draft motor, and blower, while constantly monitoring flame sensing and safety switches to prevent system failures.

Yes, the ICM2805A is fully compatible with twinning. You can pair it with an identical unit to manage two furnaces working together, provided the installation follows standard twinning configuration procedures.

The onboard diagnostic LEDs provide immediate visual feedback on the system's status. Instead of guessing where a fault lies, you can check the LEDs to quickly identify issues with safety switches, flame sensing, or ignition, which significantly speeds up troubleshooting and repairs.

Yes, the board is rated for 120/240 VAC at 60 Hz. It is versatile enough to manage various furnace components, including blower motors and electronic air cleaners, within those voltage parameters.
