Frequently Asked Questions
How do I know if my control board has failed?
Common signs include: the water heater won't ignite or heat water, temperature won't stay consistent, error codes display on your RV's panel, or the unit powers on but doesn't respond to temperature adjustments. If you've confirmed the heating element and gas supply are working, the control board is likely the issue.
