Kenwood prospero wont start

Check the power supply: Ensure that the food processor is properly plugged into a functioning power outlet. Sometimes, a loose connection or a tripped circuit breaker can cause power issues.

Safety interlock system: The Kenwood Multipro 910 food processor usually has a safety interlock system that ensures all parts are properly assembled before it can start. Check if all the components, such as the bowl, lid, and blade, are correctly locked into place. If any of the parts are not properly assembled, the food processor may not work.

Motor overload protection: If you have been using the food processor for an extended period or with heavy ingredients, the motor may have overheated and triggered the overload protection mechanism. In this case, you will need to allow the motor to cool down for some time before it can restart.

Fuse or circuit breaker: Some food processors have a built-in fuse or circuit breaker that protects the motor from electrical surges. Check if your food processor has a fuse and ensure that it is intact. If it has a circuit breaker, reset it if necessary.

Mechanical issues: If none of the above steps resolve the problem, there might be a mechanical issue with the food processor. It could be a faulty motor, broken wiring, or a malfunctioning switch. In such cases, it is advisable to contact the Kenwood customer support or take the appliance to an authorized service center for repair.

It is likely to be the selector, the control board or the motor. Take it in for Dealer Service.

If you have a multi meter check the box caps and resistors for KM 2XX series then replace it whenever required. Some may differ in values like 0.15uF 275x2, 0.33uF 275X2 or 0.47uF 275X2 then resistors may also differ with different models but common to have 1.1k ohms 2watts. Also if caps are open it is good to check the 600V triac and replace it when giving out lower output. I also advise to clean the commutator esp when is is sparking a lot, you may use light sanding and clean it after. Check also if the tachometer is good, there is a resistor-like-coil hidden under a plastic tab with 2 wires. This gives feedback and via a magnet attached to the shaft. Check the motor brush if it is good or worn out. Lastly check all the switches because if one of them is not working properly you wont be able to let the motor run.

Your control board is probably going out. Will need to replace eventually.

In my case, capacitor C1: 470nF (on the circuit board) proved to be the cause. It measured only half its normal value. It's part of a voltage divider used in place of a transformer. Replacing it solved the problem.
Came already across the same problem in another circuit.

had the same problem with Kenwood Prospero.
look for 2 pairs of watty (1.1 kohm 2W?)series resistors. At junction of the
2 pairs there is glue which degrades with heat and becomes conductive. CAREFULLY scrape away the old glue after removing the resistors. Check for shorts and resolder the resistors. You may be lucky. I was

need clarification. what does cut out mean? The motor stops altogether? The beaters stop spinning but you still get motor sounds? It comes on and goes completely off while in use and then comes back on. is there ever a bad smell or smoke? Are there any unusual sounds that you hear before it does a cut out or after it comes back on? Does it ever go up or down in speed on it's own. do the attachment gears on top spin while you are mixing in the bowl? we need to narrow the field of questions down to get to the right repair path. Please let us know.
