HOW DO I GET A COPY OF OWNERS MANUAL OF A ENGEL MT45FG FRIDGE

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.

Enter "Engel Perth WA" and do a search.

Goggle to find out the company that built it and see if they will send you a copy or if its available for download. This is a common problem with private sales without all the manuals that come with it. Sometimes you have to look up each appliance or model. Start with a phone number to the manufacturer and work from there. Also you can find someone that is selling one like yours and call them to see if they can send you a copy from their manuals.

we see a lot of this have the thermostate replaced they cost around $40 us

the owners manual will tell you but yes most do

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.
