Question about Kenwood Food Mixers
There is a Triac that controls the speed. It is probably short circuit.
A qualified Electronics engineer with mechanical skills can repair it.
Probably a BT139-600.

The 0.1 microfarad can be safely replaced with a 275 VAC 0.1mF mains capacitor. You can remove the clip that held the old electrolytic capacitor by sliding the old capacitor out and squeeezing the metal clip so that it disengages with the plastic base. The load resistor is 450 Ohm 15W or 20W wirewound. There is a 56 ohm resistor in series with the capacitor which helps smooth the speed change and reduces wear on the contacts. A 2W wirewound resistor works best. (It is worth removing the contacts and removing any pitting or carbon build up with fime emery paper). I have repaired about 20 speed controls sucessfully with these components.

could be one of three things
1) the belt is broken to the main gearbox (fairly easy to replace if you can get one)
2) a gear has slipped or broken which means none of the front end will operate.(I have this problem and cannot get the gear body to open)
3) If the top and front worms are turning then the problem is with the planetary gear which again is fairly easy to replace
