Frequently Asked Questions
Q: How do I know if my relay board is bad?
A: Common signs include the fridge not switching between gas and electric modes, failure to power on/off, or no response to thermostat adjustments. If you've confirmed power is reaching the unit, the relay board is often the next component to check.
Q: Will this board work with my older Dometic fridge?
A: This relay board is specifically designed for Quotient and SMX series models. Check your fridge's model number on the data plate inside the unit to confirm compatibility before ordering.
Q: Is this a difficult installation?
A: Relay board replacement typically requires disconnecting power, removing the fridge's control panel cover, and unbolting the old board. If you're not comfortable with electrical work, we recommend having a qualified RV technician handle the swap.
