I have a 5 YO upside down fridge. The fridge and freezer work fine, but every 4 or 5 days the power is tripped, and if I don't check the contents everything goes off. Has anyone experienced the same issue? How can I fix it? I spoke to a refrigerator repairman and he said he'd charge min $600 to take it away and check it!! Any help appreciated. Thanks Ged
