I have a Fridgedaire, model FDE336RES2. It's probably about 8 years old and has just this past month started schreeching when it dries. It still appears to be drying normally, but the screeching is gradually getting worse. Our dryer's always been warm/hot on the top and back while drying, that's nothing new, so it really just seems to be the screeching noise that's "new." I tried going on to the Fridgedaire site, looking at troubleshooting, but this is not something that was addressed. Help?
There are several things that will make a dryer noisy. Here's a list of a few items that I know of. Some may or may not apply to your dryer: FIRST OF ALL, BEFORE SERVICING THE INSIDE OF ANY DRYER UNPLUG THE UNIT OR TURN THE CIRCUIT BREAKER OFF. 1. Drum rollers worn out. Most dryers have some sort of drum roller that supports the dryer drum. There are two mounted under the drum in the rear of the dryer. Some models will have an additional set of drum rollers under the front of the drum as well. You may also here the drum thumping too. Lubricating them with a good quality turbine oil at the point of the spin shaft will get rid of any squeaks or squeals. DO NOT oil the roller wheel as it will slip on the drum. 2. Dryer drum seal. This is a felt gasket or seal that is glued to the rear ring of the drum. When they get old they become brittle and pieces start to break off leaving bare metal scraping against bare metal. They also can become folded and part of it will be seen poking through the back of the drum inside. This seal should ride evenly around the outside perimeter of the drum and should not be seen inside the drum. 3. Dryer drum support glides. Some dryer models have teflon plastic support glides mounting around the ring of the front of the tub, or will have teflon supports mounted under the front of the drum. In either case, if the plastic gets too worn down, the dryer will start to make a scraping noise. 4. Idler pulley. This is a little pulley that provides tension on the dryer drive belt. It is located near the drive motor and can start to make noise. Usually a little bit of lubrication at the point of the spin shaft will get rid of the problem. 5. Dryer drive motor. Sometimes when the drive motor gets a nice collection of dust build up around it, the motor will make noise as the impeller rubs against dust or any other debris caught. A stiff cleaning brush and a vacuum cleaner will help get rid of dust accumulation around the motor. Now, there is a possibility that the bearings in the motor could be going bad too. You would need to remove the drive belt and check to make sure the motor free spins with no power applied. Give the motor shaft a spin. It should glide free with no noise. 6. Dryer drive belt. When the belt gets old it will develop a "glaze" on it and start to slip around the drum. This can causing a squealing noise, especially under heavier loads. This is usually a prelude to the belt breaking. Start with the easy and simple options first. Try lubricating any drum rollers or pulley rollers. DO NOT get oil on the drive belt. Lubricate the rollers at the point of the spin shaft only. Inspect the front and rear of the drum. The seal will be in the rear. Make sure that it is intact and good condition, and make sure it has not folded inside the drum. Also, check for glide supports around the front of the drum and make sure there are not areas that are worn down. Another thing that COULD cause noise, but may not be associated to the problem you are having, are foreign objects getting lodged between the dryer drum and casing. Screws, paper clips, nails, etc., have been known to get caught in these areas and will make some awful noise. If you try everything and the unit still makes noise the drive motor bearings could be going bad. This is usually not likely and the motor can be very expensive to replace. Last of all, some heat on the top and rear of the dryer are normal. However, if it is excessive (you can't place your hand on it and hold it there), you probably need to give the inside casing a good cleaning. This could be a sign that your dryer ducting has become clogged and the unit is actually overheating trying to fight for air. Ask yourself, "Are my clothes taking a longer time to dry?" If the answer is "yes" then you need to clean the unit out and check the entire length of the ducting to ensure it is blowing air out of the vent. Remember also, the shorter and straighter the ducting run, the better. Any sharp bends or kinks (behind the dryer) will cause lint to back up. I hope you find this advice helpful. Good luck and let me know if I can help further.
