Hi, I have an older Inglis dryer model TO-84100 and it started squeaking really bad but I'm not too sure what it may be? Anyone have any experience with these dryers and know if the motor is going or is it some bearing that's going on it? Thank you

What you need to do is to remove the dryer from laundry room and take it apart. When you pull it out from the wall and unplug it you will be able to see what you need to do in order to take it apart. It is not that hard to do. Have dryer on its back to make it easier to get the drum out. The first thing you want to do is to clean out everything very well which means to remove parts that move air and wash them out with soap and water, including door and blower fan. Just vacuum out motor. A rear drum bearing can be causing your problem, but it may have support rollers supporting the drum and an idler/tensioner pulley that has to be greased with white lithium grease, but cheap replacements can be ordered if the bearings are ruined. You always grease bearings in a dryer with white lithium grease, available at any appliance or auto parts store. If the bearing is not scored then you can clean it well and re-grease it put it back in, but if scored, which it probably is, then get a new one that comes in a kit, as it is fairly cheap. You also want to get a belt for the dryer unless you want to do this again in a month or two. It is only about $5.00. Put it all back together and test the drum by rotating by hand to make sure you have it right because many errors can be made in putting it back together. If you have labeled all wires when you took it apart you will have no problems. See: https://dl.dropbox.com/u/8010163/Kenmore%20Dryer%20Manuals.zip

Thanks for the quick reply! I actually think it was the idler tensioner. Because I sprayed it with some wd40 and after a little while the sound died down but was still there when I kept it running for a bit longer. But I did notice that it would only make the noise when it was colder than -15C. So I think it could be the belt but I'm going to have to wait until the temperature drops to test it since we have been having nice weather lately.

I use WD-40 as a test to see which bearing is making the noise, but when one makes noise you might as well get a set which will cost about $20.00. I would get the idler pulley and the support rollers for the drum. If it has a drum bearing, get the kit. Always clean it once a year, minimum, or if you wash a lot of clothes in a cold climate you should clean it more often. You will see how much junk collects in a dryer which will catch fire.

I don't know who makes your dryer, so here are all the manuals.
