The fuse & distribution board is a pretty simple printed circuit card with no exotic components on it. (Sometimes two boards stacked together).
Speaking from 45 years of electronics experience, my expert "guess" is that one of the copper traces (sometimes called "lands") on the back side of the card has acted like a fuse and opened. It would be pretty easy to find, especially if you correlated it to which fuses were hot and which were not.
If this were my unit, I would solder a piece of wire across the break. I've done it before--on my dishwasher, on the circuit card of my son's residential clothes dryer, and on the engine computer of my 1992 Mitsubishi. And many more.
If you don't have experience doing this, you could simply buy a new distribution board--you don't have to buy the whole converter. Both WFCO and Progressive Dynamics will sell you the board; they might even give it to you under warranty.
If you do replace the board, here's a hint.
- Disconnect from 120v shore power.
- Disconnect the negative cable from the battery.
- At the distribution board, label and disconnect wires to the converter and to the battery.
- Now, holding the new board in one hand, one at a time, remove an individual fuse wire from the old board and connect it to the new board. Repeat until all are transferred.
- Unmount the old board.
- Connect the converter wires and battery wires to the new board.
- Mount the new board.
- Transfer all the fuses.
- Reconnect the battery cable at the battery.
- Reconnect 120v shore power.
