If your dryer takes an hour or longer to dry clothes, here is what to do. First check your vent and ducting that goes outside of your house. If there is a clog or some type of obstruction it can cause your dryer to improperly heat. Check your heating element too; sometimes just a part of the heat element can burn out. In this case your dryer would still heat up, but it would take a longer period of time to dry your clothes. If your heat element is burned out in one section, you should replace it. Your dryer also has internal ductwork. If this gets clogged, then your dryer will not dry properly. In most dryers you will have to actually disassemble it to get to the ductwork. However, you can check for clogs by removing the lint filter, and use a flashlight to inspect the ductwork. You can use a vacuum to suck out the obstruction. A less common problem is the cycling thermostat. The cycling thermostat is one of the thermostats that control the temperature in your dryer. If this breaks it can cause your dryer to take longer to dry clothes, if it is broken you will need to replace it.

If this is the problem, you should replace them as a set. The idler pulley keeps tension on the drive belt, and when it gets worn out, it can be noisy. You should replace that if it is worn out. Dryers use either plastic or nylon glides, located at the front of the drum, for support. Again, if they are worn, replace them. Some dryers have drum support by using a center spindle instead of wheels. The spindle could be a shaft through a sleeve style, or a ball and socket type. When these get worn they can make an awful squeaking or squealing sound. They cannot be repaired, just replace them. The blower wheel pulls air o
