Can you post the model number please.
Ok what you need to do is pull the washer out and remove the top.
From there you will see the dryer fan in the back right corner.
On there is a small belt. Check this is on ok and that you can turn the motor easy on there.
Then set it going on dryer mode and see if the fan motor kicks in. It doesn't start straight away it will take a few minutes. But let me know if it does kick in after that.
