Frequently Asked Questions

How do I know if my refrigerator control board is bad?
Common signs include the fridge not cooling, failure to cycle on or off, temperature fluctuations, or the unit running continuously. If you've verified power is reaching the fridge and the cooling unit itself is functional, the control board is likely the problem.

Is this a direct replacement for my RM Series fridge?
Yes. This is a genuine OEM Dometic part designed specifically for RM Series refrigerators. It installs directly without modifications. Always verify your model number matches before ordering.

Do I need special tools or technical skills to install this?
Installation typically requires basic mechanical ability and a screwdriver. Most RV owners can handle the replacement, though some models may require removing interior panels. Consult your refrigerator manual for specific installation steps, or contact our support team for guidance.
