Fridge Temp Control Question
I have a Dometic S630 absorption fridge from 1991. AFAIK newer ones work the same way. Apparently the freezer cools down and then eventually the fridge cools down to its proper temp range just above...

I don't know if the terminals for the 12v element on the board, when seeing the 12v would "back feed" the board, same as if the board were getting power from its regular 12v inputs.
Yes, it would likely back feed into your whole RV 12V system. If you do want to go this route, buy a 12V relay and use the wires heading to the element to power the coil and then use whatever voltage the 12V element can take through the switches terminals to the element.
I don't quite follow the relay set-up, can you "dumb it down" for me? Thanks.
I am thinking the 12v terminals to the element are switched by the temperature control to do the cycling, so you would still need 12v steady into the board via the 12v input terminals.
The trick would be to get 15v at the element wires from the terminals externally from the board, splicing into the wires, but to also leave the wires on the terminals, but then how would the 15v to the element be switched?
Right now, I go through the board with max DC input, but have some voltage loss in the board, reducing element wattage.
