My 2010 Dometic RM2852 (8 cu ft) refrigerator no longer maintains 40 F on electric or propane although the freezer is OK... I already replaced the thermistor, added 12V fans & temporarily swapped control boards with no improvements so IMO the cooling unit needs replaced.
My 1st option is to replace the cooling unit with a NEW Amish-redesign (not refurbished) for $710 (shipped). The thicker coils & better boiler design are supposed to last longer & handle higher outdoor temps better than OEM...
My 2nd option is to install a new $400 Whirlpool 10.6 cu ft residential fridge(WRT111SFDB), $300-500 Inverter/Transfer Switch (Xantrex Freedom?), (2) 6V Deep Cycle Batteries ($300+ for 2), plus misc. 0 gauge wiring, etc.
I can install either option myself so it comes down to price... What is the best bang-for-the buck inverter, transfer switch, and (2) battery option that will handle the 10.6 cu. ft. residential fridge? (I don't have room/budget for 4 batteries...) Thanks in advance!
