How do I know if my fused circuit board needs replacement?

Signs include repeated blown fuses, loss of power to specific circuits, tripped breakers that won't reset, or visible burn marks on the board itself. If you're losing power to multiple 12-volt systems simultaneously, the circuit board is often the culprit.

Is this board compatible with my RV model?

Part# 90145 fits multiple Dometic systems. To confirm compatibility with your specific RV, check your owner's manual or contact our expert support team with your RV model and year. We can verify the exact fit before you order.
