Hello,
I have a Samsung WDO8O4WSE ecobubble washer dryer that is between 2 to 3 years old. There are two thermostacic sensors built into the heating duct of the dryer, one of which has a little white trip switch that keeps tripping during every drying cycle thus stopping the heater element from working. Ive cleaned out the wash filter, but perhaps there are further lint filters or outlet pipes that need unblocking or the sensor is faulty?
You need to change the whole assy,its called a duct scroll.
all the internal channels are fluffed up and restricting the airflow thus causing the thermal trip to activate
