Hoover dynamic next no spin

Hi Jim. Unfortunately there is a chance that when the motor blew, it damaged something in the main PCB. But it's also possible there could be a dodgy connection somewhere. The main thing to check is the motor plug to make sure that it is inserted properly and that none of the pins have been pushed out so that they are not connecting inside, which can happen.

If you can't see any obvious problem with the wiring harness and connection, and we are assuming that it is the correct motor and there is nothing wrong with it, then it might be worth seeing if you can see anything blown on the PCB. However, make sure it has been unplugged for at least 10 minutes before touching it as some of them can hold a nasty electrical charge even after being unplugged.

Don't mistake any black soot on the printed circuit board that wipes off for anything untoward as it is very common for resistors that get very hot to attract a lot of dust that turns black. You should know if something is physically blown. Unfortunately these PCBs can be expensive and you are in a tricky position. I would be very cautious about replacing the PCB, particularly if you cannot actually see anything wrong with it. It might be advisable to see if you can return the motor?
