I have a 2007 Dometic DM2652 and it had a blown 5 A fuse - in the fridge, not at the inverter. I got a few 5 A fuses at AutoZone and the fridge has blown two of those. I checked the voltage at the outlet and it is 116.8 V. I have the fridge running off of gas right now. Any ideas as to what might be wrong? Thanks!
