Frig. - Eliminate 12V DC Heating Function

[Curt Sprenger]

Our Bird frig. is the 3-way Dometic RM3801. It may be the original unit.
I'd like to disconnect the 12V DC heating (cooling) function, so it
becomes a 2-way elec. 120V or gas unit. Can this be accomplished? Has
anyone done this? I read about the replacement Dinosaur Board, that a
wire can be cut to eliminate the 12V DC heating function.

My experience is the people at Dometic are very
helpful via telephone and will have suggestions and
guidance, and even help to find "out of stock" and
upgrade boards. Have handy, both your refrigerator
serial number, and the cooling unit serial number
before you call, however. It's apparently the way
they locate appropriate schematics.

Obviously don't know about your unit; however, ours,
and 2 I've looked at since my discovery, indicate
Bluebird wired the 12V directly from the battery bank
to the rear power supply board (accessible via the
outside panel) through an in-line fuse holder, then
stuffed/pushed it back into a cabinet hole. It is
easily overlooked because the fuse holder is
wrapped/covered with electrical tape and looks more
like it covers a "wire splice."

Hi Curt:

If you install a Dynasaur P-711 board, look at the power left corner. There
is a selectable switch there, failing that, J-1 is the control from the
board to the 12 vdc heating element. You can simply clip the "bar" on J-1
and do away with the 12 vdc heating part.

Safe travels,

Curt,
I put a new dometic frig. in 1998 and cut that wire out. It has been working
fine without it.
