Is there anywhere in Tasmania Australia to get my engel repaired?

You are lucky it lasted this long. Replace it. Parts are not available, and if they were, the cost to repair the unit is far more than a new Fridge.

Sorry we do not have that kind of info here.

Check for power at the unit "Always disconnect power before trying to repair any appliance."

Axe????

You may have to go for a repair.

AUTOMATIC AC/DC CHANGEOVER: All Engel Fridge Freezers can be plugged into both AC and DC at the same time. The Engel is smart enough to use the AC while available and then automatically switch to DC when the AC is no longer working. It will also sense the resumption of AC power and automatically switch back to AC making it ideal for high hurricane areas and places where power disruption is common.
