Hi Terry
Same thing happened to mine yesterday. I had bought mine 2nd hand about 1 year ago and was working OK, then likes yours it simply cut out while using it.
Tried the obvious and changed fuse, still no joy. Like you have taken casing off to look at motor etc, but nothing seems to be amiss.
I noticed you did not get any replies to your post from June. Did you manage to find out from other means what the problem was. If so please let me know.
Thank you.
