Thanks Tim.

I'm not aware of any problems with my controller or computer. I notice 
that there are micro switches to protect against over-run, and wonder 
why these didn't protect the motor, if one of the circuits had stuck on.

BTW  have there been any improvements with the sealing against rain 
water on this model? It seems better than the previous model, in this 
respect.
