Thanks drtom4444 for your quick response but I have one more question where are the sensors for that kind of dryer? Just got home took dryer apart almost finish cleaning with soap an water just can't find sensors so I can clean it too.again thanks for you all you help...

The sensors are all along the duct work where you have air flow. Most of the time they are oval with a round center where two wires are attached. Some of these are safeties. The only way to know what they are is to look at the numbers stamped on them. The highest numbers are safeties, like 200 or 220, then sensors will be marked at 180, 160, etc. As long as they are all cleaned along with duct work you should be okay. Was there a lot of dirt in the ducts? Be sure to be thorough.
