So I'm very grateful for this posting I've been trying to solve the same issue and kept looking past the thermofuse!

1. If you have 12 volts on the Brown AND NEG(GROUND) at the Green the board is bad
2. WHERE did you get your replacement Board? The reason I ask is, Atwood(Dometic) had hundreds of thousands of BAD boards a few years ago and they pulled ALL replacement boards from suppliers and replaced the Boards on all WH stock. DEALERS(Service Centers) if they had any sense(a lot don't) could send in their bad replacement boards and Dometic would replace them. But, since some business's are not honest, or just stupid, they would then sell those bad boards or someone on the Internet got hold of those bad boards and would sell them on the Internet. Because of this I would advise ANYBODY to not buy Dometic WH control boards off the Internet for a few more years. These BAD Boards did work but would fail after a few days/months. Some did fail at first operation. There is now way for Dometic to track the BAD boards. There is NO way for you or anybody to determine good new boards from the bad boards. It would appear you got a bad replacement board. Doug

That WH-G6EA is a brand new revision...Dometic FINALLY moved the electric element/DC Relay from backside to Front of WH Tank....YEAH
WH...(Product ID_
G ...(GAS)
6 ...(Volume)
E ...(Electric)
A ...(Revision)
Combustion/Exhaust 'U' Tube is now Stacked vs the Diagonal on previous version (to make room for DC Relay/Element
DC Relay/Element is under that cover on right bottom area in outside compartment
Wiring scheme is same as a GC6A-10E/GC10A-4E versions (from 2004--present)
So you verified that you have 12VDC from On/Off Switches to circuit board
Orange wire....Gas
White wire ....Electric
You verified you have 12VDC on Brown wire from circuit board to/thru thermal fuse, to/thru T-stat and back to circuit board via Brown wire
Did you remove that 2A fuse and verify it has continuity?
Second Board not working either
Thermal Fuse (in clear tube) if blown will stop ALL DC back to circuit board
Remove it and jumper Brown wire straight to T-stat
2A fuse protects the circuit board
So if blown then there is a short in circuit board
2 Boards...doubtful
Check ALL the ground connections Pin 6 & 5

I only have an old WH but it does have the board with a 2 amp fuse. I think you are saying you by-passed the big plug with the pos wires that goes into the circuit board, and went to the fuse and then it all worked.
It can happen that plug, if it slides onto the edge of the board, loses good contact. Cure is to pull it off, clean off the contact part on the board and anything in the plug contacts and put it back on. Wiggle it some, see if that gets you contact again.

No power after that point to the fuse. I dont know much about these and assumed it was the board.
Which hot wire did you jumper to the fuse and then it worked? That means the wire or where it is from is no good, not the fuse or the board. Whyinheck would you buy a new board for that? Or else I misunderstand ?
