I have a kenmore dryer... fairly old but nevrr problems. It is shutting off after running for 10- 15 minutes... does it on any cycle I put it on... suggestions? It will run again for a short period... even dors it on lowest setting! Help please!

These driers will overheat when the lint builds up like concrete on the inside of the air ducts. They blow the main safety to keep it from burning the house down. Halfway cleaning it will not work. If the fuse blows you need to totally tear it down and scrape out and wash all of the parts except the motor, which you vacuum out. You can go to YouTube to see videos on how to take it apart, but do a very good job or it will fail again quickly. I would get a new belt and change it while you have it apart and get some white lithium grease and grease any bearings you find. You need to clean out a drier every two years, at least, according to the manual. You just unplug the wires from the sensors and remove ductwork that they are attached on and clean the entire thing with soap and water. Make sure you go all through the dryer and get all parts like the blower fan and housing, vacuum out motor well and clean exhaust. Mark all wires you unplug so you know where they go. This is an easier job than you would think. Make sure to clean around all of the sensors, too, because when they cannot sense the dryer will not work, plus the burning lint deposits will burn down your house. The blown safety is like a fuse and located near the elements, but there are several strung together in series, so you have to go from one to the other until you find the one that has infinite resistance. You will need a meter to find the safety that is blown . Replace the belt which you can get the same place that sells a new safety. You also have a safety in the motor windings and a dirty dryer will cause it to overheat and turn off everything. Once you clean it out well you can see any problems left which may be few, if any.
