Ok, great thread… but …. sort of curious as to a slight twist on the OPs issue.
What if the issue is with running the 3 way fridge on the 12 volt option?
We have no apparent issues with fridge or freezer temps keeping up if on propane or shore power… only issue seems to be when it was running on 12 volts the fridge doesn’t keep up. {We were hoping to use 12 volt option as we are in a 2004 Arctic Fox 990 and upgraded to a Renogy 40 aH dc dc charger as well as flooded lead acid batteries (2 x 100 aH) … we just invested in 2 new 260 aH (actually 280 aH but tuned to 260 aH) for a total of 520 aH LiFePO4 batteries which arrived today and being installed (obtained from sunfunkits dot com if anyone is looking for an affordable option but not feeling like building one yourself) - but I digressed,sorry! }
Do you also think that #4 fan kit would also resolve the issue we are experiencing with the warm temps in the fridge when it’s running on the 12volt setting?
