Apparently……..some of the “blue spot” stats are of a higher temperature so it is important to order by model number – the higher temp stat has no blue spot I am told.
Another cause is that the motor capacitor – it has been changed to 8mf I think. The problem was that the drum would stall mid cycle making the stat get too hot and go oc.
Still have yet to solve mine though! going back tommorow & will report back 🙂
