Frequently Asked Questions

How do I know if my furnace control board has failed?
Common signs include the furnace not igniting when the thermostat calls for heat, the burner lighting but shutting off immediately, no response from the thermostat, or the furnace cycling on and off repeatedly. If you've confirmed the propane supply and thermostat are working, the control board is likely the issue.

Is this a direct replacement for my DM Series furnace?
Yes, part number 9108919301 is designed as a direct OEM replacement for Dometic DM Series furnaces. No modifications or adapters are needed—simply disconnect the old board and install the new one following your furnace manual.

Do I need professional installation?
While many RV owners can replace a control board themselves, furnace work involves propane and electrical systems. If you're not comfortable working with these systems, we recommend having a qualified RV technician perform the installation to ensure safety and proper operation.
