Sanyo Sr-3770s Running But Not Getting Cold...

hey guys, before i start i want to say thanks in advance for any help or suggestions. i just recently bought this mini fridge used and the owner said it worked fine. well it didnt. he had it stored in his barn we plugged it up and you could hear it run so i bought it loaded it up and took it home. let it sit over night. plugged it in and like i said its running but its not gettting cold at all. i have tried bypassing the thermostat i let it run for over an hour nothing. if there is anyway to do a quick fix on this fridge just to get thru the weekend i would greatly appreciate it. that was my whole reason for getting it. was to help out with drinks and smaller stuff. thanks for the help guys
