All of 6 days after we set a goal of saving $6,000 this year our refrigerator died. Because it is the middle of winter we were able to just put stuff in big plastic boxes and set it out back while we figured out what to do about our broken fridge. I went online to find an appliance repair person and I noticed a startling trend - about a third of the reviews for everyone I saw said something like, "He came out and vacuumed out the coils and it started right back up! Well worth the $120!" Well, if that is the case I will try that myself first!
So I got the vacuum and unplugged the fridge, removed the front grill and noticed the underside was full of dust and pet hair. So I vacuumed it out. I got a flyswatter and dug around under there, bringing bits of dust from the back up where I could reach them with the vacuum. Then I vacuumed the entire back side of the fridge and plugged it back in. It worked! We now have a functional refrigerator again at the low, low price of $0. Actually better than that, since the fridge was unplugged for 2 days that probably saved us a couple bucks on the electric bill too. Score!
