If your dryer runs, but it isn't heating, test the thermal fuse. The thermal fuse is a small safety device that cuts off the dryer when it reaches a set temperature.

Having problems with your refrigerator in the hot summer months is no joke, as you scramble to find a temporary home for your food to avoid it spoiling. It's generally a good idea to call an appliance repair person as soon as you notice an issue with your fridge, given that it might take several hours or even a day until someone can visit your home. Although you'll be primarily occupied with dealing with your food -- perhaps enlisting the help of a neighbor's fridge or a couple coolers filled with ice -- it's wise to invest a little time in preparing your fridge for the repair person.
