If the 5-amp fuse only blows with the DC heater plugged in, the DC heater (or its wiring) is shorted. That's probably what caused the original error too. Check the DC heater from each lead to its metal housing (it should read open). If it shows continuity, replace the DC heater. The fridge will keep running on AC and LP without it.
