problem i'm having is with the dometic Model RM2354 3 way, single door fridge.
works great with 120 VAC and propane but if turned to 12v it blows a 5 amp fuse in the little breaker/fuse panel inside the camper (not outside). the furnace quits working also when that 5 amp fuse blows. lights are ok
In a nutshell, that model pulls
12.5 amps just for the DC heating element alone. So a 5 amp fuse is going to blow all the time. (see page 11 of the service manual for the DC requirements). In addition, the DC element was not designed for continuous use but rather to maintain cooling while "traveling".
Just to add, the 5 amp fuse probably is for the DC control portion while on A/C or Propane; not the D/C heating element. You need a separate dedicated line and fuse if using the D/C full operation for the heating element if your RV wasn't wired for it.
