This started to make a burning electrical smell and then stopped. Trying it again later it started briefly then stopped - for good. It looks as though one of the capacitors has gone as its case has ruptured. What are the chances of it working again OK if I replace this capacitor?

turn chef upside down open cover open machine there are two screws ,unscrew you should see the capacitors it depends on what type of speed controller it is the black one is the simplest having less components 1capacitor is .1uf and the other one is .15uf the resistor is 56ohms be careful to replace one after the other. it is worth it to repair these machines
it is a good idea to check the brushes too.
