If Tom's not in town (I don't have his number handy, but if you search on the forum, you should be able to find it)....try Mr. Fix-it....Pablo Bustamente....638-113-4594
He speaks english fluently.
BTW, if you're talking an RV refrigerator (ammonia cycle)....if it ain't working, you've probably lost the coolant. Not sure if you'll be successful in finding anyone in town to fix it...
