Dryer was professionally installed.  However the dryer only worked for approximately 12 days. 
 It left clothes damp and wet.  Dryer would run for 2-3  minutes and stop. 
Repair man could not find just one single problem but diagnosed as series of possible causes : Bad  solenoid , bad door closer sensor, bad motor and bad moisture sensors. 
Family had no dryer for over for 3 weeks waiting for repairman's analysis and replacement dryer.
