Blakeslee (Kenwood) A717 mixer speed control

Well done Leonard. Easy fix.

It is not a make I have heard of before, which is odd, because I spent 50 years in catering and hospitality. Parts are available according to this. Getting to the snap ring would be the issue. You may be able to pull the old one out with a right angle pick and push the new one in.

Question edited for clarity.
Question moved from Cars and Trucks to model category.

The OP, George supplies the answer.

Update solved: problem was the tiny speed control sensor mounted above on the motor with three cables.

These show up on E-bay all the time.

How old is your appliance?

If you are just getting one speed at any speed control. Its likely that the speed control mechanism ( probably an electric one has been damaged due to ailing parts). Likely component which may fail over time are electrolyte capacitors. Take a look at the circuitry inside the food mixer.

You may need to change some parts to get back the control.

KMX50 would start and accelerate to high speed, then slow down some with fairly erratic speed. I tried changing the triac on the main speed control board, then also the whole board (£45). It made no difference.

The only other component I realised it might be was the speed control board which is on the rear end of the motor under the main cover (I found this component on a site selling Kenwood parts, and was where I got the main board from, which is how I know it's speed control). When I inspected it I found two of the terminals broken. You had to look very closely to see they were broken. It's a poor design as the three legs of the terminals are quite long, and very thin, so on high speed when kneading there is much vibration, which is why I suspect the terminals broke. I cut them back just enough to resolder. The component isn't quite fully inside the sensor wheel on the motor shaft, but it still picks up sufficient signal to control the speed and now works fine. Haven't tried it under load yet, but no reason to think it won't work correctly. So check this before ordering a £45 board!

The switch on the titanium has a flimsy week point and is always breaking. This is a stupid economy by Kenwood when there is now so much good competition. Mine broke after only 6 months and Kenwood were less than helpful suggesting I took back to where I bought it - 500 miles away!! I wish I had bought a Kitchen Aid

i have the manual i can email it to you! [email protected]

Hi,

where are you from, i have phone number to agents that still provide support for A700 series.

The speed control is a governor setup, it's purely on and off, as the weights on the motor shaft spin faster, they press against the contacts, and when they spin a fast enough speed, it turns off current to the motor, which makes it slow down, and current gets turned back on.  That way, you get a pretty consistent speed on a setting no matter whether it's lightly loaded or whipping something fairly heavy.  If you can turn the motor shaft by hand, then you don't have anything binding, but you might have gotten the speed control out of adjustment.  give it another go.
