Dometic NOS Passport I/O Circuit Board for Self-Contained Marine Air Conditioners

This new old stock Passport I/O circuit board is designed to replace your existing board, provided it lacks a large transformer. To verify compatibility, check your display’s programming menu: if it begins with a "P" (e.g., P0, P1), this board is suitable; if it starts with a "U" (e.g., U1, U2), replacement requires a new display as well. This obsolete PCB-372 features four telephone jacks and has been superseded by a U-Board with three jacks. Only one unit is available, backed by a 30-day warranty.
