We really need to know more about the fridge. Make, model, etc. That info can usually be found on the door. We also need to know exactly what's not working about it. Does it work on electric. Does it work on propane? Does it not get cold enough? We also need to know if you have a battery and is it charged?
Having said that since they stated it had a recall on it, it's most likely a Dometic. You can use the model and serial number and go to the Dometic website and enter that info and it'll tell you if your unit is part of the recall. Keep in mind that just because it's part of the recall it may not be why the unit isn't working so the recall may not help you.
Let us know any of the above requested info and we can certainly confuse you more if we can't do anything else.
