My psycho Kenmore dryer (it will turn 2 years old this upcoming July) is getting too hot and shrinking my clothes. The first Sears repairman said the thermastats were bad and he replaced them. Then he said it was actually the knob making the theramstats go bad. He didn't have the part but he would mail it to me. He showed me how to swap out the knob electronics, which I did. That didn't fix the dryer. Sears sent a second repairman out. He said the dryer was fine and the vent was clogged. The dryer vents out through the roof (1 story house). The repairman claimed that the vent was at least 20 feet long and vents can't be longer than 10 feet - dryers simply can't handle it. He told me to chop the ductwork and vent the dryer into the attic. Yesterday a chimney sweep confirmed that the dryer is vented properly AND the ductwork wasn't clogged up or dirty. This psycho out-of-warranty Kenmore dryer is still heating up uncontrollably. Sears' only response to send a third repairman out a week from tomorrow. I'm on the verge of buying a new dryer and demanding my money back from Sears for these bogus repairs (and the chimney sweep). HELP!! Is there a part I can replace on this thing? Or should I pony up for GE with a 5 year warranty?
