My son recently sold his Project Debut TT to a friend. It has since developed a fault in that 50% of the time it starts up spinning in the wrong direction. Why would this be?

Capacitor gone out of spec?

It's probably an AC synchronous motor, so it will be affected by the mains phase.

I had a motor that mostly went backwards. It that case, one of the windings had gone open-circuit. Also, as Chris suggested, a dodgy capacitor would cause the same fault
