Hi I have exactly the same make of dryer and the exact thing just happened to me this evening. I found a fix for this which is very very very easy and may well sort your problem out as it did with me. Go to the following link page and follow the instructions (Basically you need to reset the thermostat). Try the fix first as suggested and if it works pay the £1.00 thats what I did.Good luck Chris
