Thomas W Nashville , TN May 27, 2022 Appliance: Model DE412-02 The dryer was very noisy at start up we had a similar problem years ago and I thought that I know what the problem was. Well #1 when I removed the Front panel, the center support panel and the drum , I did not find any bad rollers. I checked the belt and it was worn but not a problem. I next checked the idler for the belt tension and did not find any problem with it. I noticed that there was a lot of lent everywhere inside the unit. I checked the blower fan and found out that it was turning on the motor shaft. Our vent to the outside is approximately 12 ft. I found probably 4 or 5 pounds of bird nest inside the vent. It took me about 4 hours to clean out the vent. I am guessing that this has been stopped up for several years. The excess heat probably caused the blower fan to overheat and break at the motor shaft. I ordered new rollers, new roller axles, new idler pulley wheel, new blower wheel and new belt. After putting it back together it sounds like a new machine.
