There are many moving parts in a dryer that can wear down over time and begin making noises. Belt tensioner pulleys and drum support rollers will often begin squealing or screeching as their bearings fail. The drum bearing can make a similar sound as well. Fortunately, these are considered normal wear and tear parts and, in most cases, these are typically a painless repairs.
Another common failure, that can make unbearable noises, are issues with the blower wheel. The blower wheel is a fan blade that forces the air and moister to the outside of the dryer. It spins at a very high rate of speed. If it becomes cracked, loose, or off balanced, it will make an incredibly loud rumbling noise.
If your dryer will not start or turn on, it may be as simple as blown fuse. Most dryers are equipped with several different fuses that will trip if they get too hot. The most common reason for a dryer not starting is a blown thermal fuse. The purpose for this fuse is to shut down the dryer if it overheats, often due to poor exhausts airflow. On an electric dryer, a blown thermal fuse will prevent the dryer from doing anything. On a gas dryer, the unit will run but will not heat.
Electrical issues with the power supply can also keep a dryer from starting. In many cases, the failure is not in the dryer, but is instead an electrical issue in the house. In other cases, a faulty timer, circuit board, or switch may be in need of replacement.
In some cases, a broken belt could be responsible for your dryer not starting. When a belt breaks, it will often produce a loud bang or pop as the tensioner pulley is released. This spring loaded tensioner pulley keeps the belt tight around the drum. Some dryers are equipped with a belt safety switch attached to this pulley. It will recognize the release of tension, and intentionally disable the dryer from running.
Drum Not Turning
Your dryer sounds like it is running, but you open the door and nothing moving. This is an indication that your belt has broken or has come off. Not all dryers are equipped with a belt safety switch. Many dryers may continue to run with a broken belt. Fortunately, belts are easy to replace and can be replaced with minimal cost.
Not Drying Clothes
If your dryer is not drying clothes, you first must determine if the unit heating. If your clothes do not feel warm or hot, you will probably need to call an expert. There are a number of things that can cause a dryer not to heat aside from just a broken heating element. Dryers have a multitude of fuses and thermostats that can fail and and disable the heat.
If your dryer is heating, but still not drying your clothes, than your likely experiencing airflow issues. The dryer may feel hotter than normal because the heat is not escaping. The most common cause for this is a blocked or restricted exhaust vent. If it gets clogged by lint, or in some cases a nesting animal, the moister from your clothes cannot exit the dryer. In many cases, this will result in the dryer taking twice as long to dry clothes. You may also experience excess moister on the inside of the dryer, especially around the door.

The U.S. Consumer Products Safety Commission estimates that clothes dryers are associated with more than 15,000 ﬁres each year that result in property damage, injury, and in the worst cases, death. Dryers rank third among the appliances in our homes that start ﬁ res, with only stoves and ﬁ xed heating systems ranking higher.
Any household electrical appliance, including dryers, require periodic inspection to ensure they are working properly. It is suggested you (or a professional) inspect and replace worn parts and clean its interior to prevent the build up of lint and other ﬁ bers that can cause a malfunction. To protect your home and family, make sure you operate your dryer with these precautions in mind:
Never leave the house while your dryer is running—a malfunction can occur at anytime, often with serious consequences. If the dryer does malfunction, immediately turn it off and disconnect the power cord. Repair it immediately.
Make sure your dryer is vented to an outside wall and check to see that its exhaust vent is unobstructed and its outdoor vent ﬂ ap opens frequently. If air is not being directed through the duct, there may be a blockage. In order to remove the blockage from the exhaust path, you may have to disconnect the exhaust duct from the dryer. Be sure to reconnect the vent and the duct before restarting the dryer.
Keep the area in which your dryer is located free from clutter. Make sure there are no combustible materials such as boxes or clothing near the dryer. Use caution when drying clothing saturated in hazardous chemicals by washing them thoroughly. Then use the lowest heat setting and do not allow contaminated clothing to sit in the dryer or basket with other clothes.
Remove the lint ﬁ lter, thoroughly clean it after each use, and reinstall it. Never operate the dryer without the ﬁ lter. Doing so can cause lint, threads, ﬁ bers, and dust to get entrapped in its internal mechanical parts where they can combust or cause other problems.
