Hello, I have a similar situation as a question posed. The dryer when set for moisture level runs continuously, whereas the timer setting works. From your answer, it appears it may be the thermostat. Is that correct? If so, it is the Thermostat net AP4037199 (item 8) or the Hi Limit thermostat AP4036956 (item 17), or is there a moisture sensor of some sort? The dryer does heat up and run. Thank you.
ANSWER Bernard, The first thing to do, set the timer in an auto sdvance setting. Disconnect the exhaust vent from the back of the dryer and start and let the dryer run for 10 to 15 minutes, empty. If the timer advannces, you have a venting issue (clogged, kinked, vent pipe or exhaust hood). Also check the blower inlet housing (under the lint filter). If the timer doesn't advance, replce the cycling thermostat first
