Lakeland Dehydrator (Five Ashes, TN20)

Lakeland dehydrator, REQUIRES REPAIR. Complete with five trays and original manual.
Stopped working recently and having undone all the easy bits, I established that the element is still heating, the fan motor is still running but the fan itself is not turning to distribute the warm air. Might be easy to fix for someone capable but beyond my limited electrical skills.
It has served me well for 6 or 7 years and I'd be delighted if someone else can get some more use out of it.
