Direct, drop-in replacement for Dometic™ “U” board systems. Supports Cruisair™ TSEP sensors or original Marine air sensors by removing RES SEL (JP5)

This is a drop in replacement board for Dometic “U” board systems made from 2016 until present. These Dometic boards are (5.3”x 4.6” [13.5cm x 11.7cm]) with holes (4.7” x 3.75” [11.9cm x 9.5 cm]). They feature red, white and blue connectors in the corner of the board, a six and an 8 pin display jack and nine pin screw terminal blocks. If the original board has these characteristics than this is the correct board.

    Excellent service from Water Yacht Solutions in providing a replacement part on time. These boards are quite sensitive though

    The board arrived on time, the warehouse called and made sure it would be there that day a marina specified while traveling. Great customer service. I installed the product and the system runs as it should. No sense of the longevity of the product

    Competitive price. A lot less than what the local dealer charges. It was shipped on the same day for free.
