Fridge not working

[2hellandback]

My fridge is not working it wasnt working when i bought the truck its a Taylor Made (Tundra T18P) brand.

Is there any tests i should run or should i just pull the 4 front screws and make sure there is power to it and if there is then just junk the fridge and get a new one ?

Take it out and blow the debris out of the cooling fins, then hook it up to a good healthy battery and see if it turns on, gets hot and then the thermal switch kicks it off again. A lot of the time its because it is overheating due to dirt on the fins, also look for a reset switch back there.
If none of that works, its time to get a new one, they usually cost more to fix than replace.
