This is the microprocessor control board used in Girard's 2GWH-8 tankless RV water heater. Girard, now a Lippert brand, builds its tankless heaters around electronic control boards like this one to manage ignition and heater operation.
Use it as a direct-fit replacement when your original 2GWH-8 control board stops working correctly or fails.
Confirm your water heater's model number matches 2GWH-8 before ordering, since control boards are model-specific.
