Clean Refrigerator Coils
If your refrigerator stops working on a hot day, suspect the coils. Service pros find this problem on half of their refrigerator calls. On many fridges, you get to the coils by removing the front grille. Then push a coil cleaning brush (sold at home centers) into the coils, pull it back and vacuum it clean. If the coils are located on the back, pull out your fridge to clean them. Bonus: The clean coils will cool more efficiently and save you money on your utility bill!
