I will try and help with this problem Hoover DYNAMIC NEXT DX C9DG-80 Condenser Tumble Dryer

as you will see in the exploded diagram below there are a few thermostats you need to check them, the most common one to fail is the 206c cutout on the heater. also check the heater that there is continuity on both sides of the element as this has high heat and low heat if all of these are good then you may have a problem with the relay on the circuit board. I have included some useful videos for you to watch below, and also an exploded diagram showing you all the parts on the machine all these are available in the links below

I have also included for future reference a full list of error or fault codes on this machine
