I thiught it would be a good idea to replace the capacitor on my Kenwood Chef A701A because of its age and before it blows!! Can anyone tell me if the 0.1microfarad capacitor on the A701A motor control board can be replaced by a maplin capacitor metallised paper 0.1mF N69CN (275V) or is it an electrolytic capacitor -I cannot see any polarity marked. If not any other known source?? I have used the above capacitor parrallelled with a 0.047mF one to successfully repair my daughters A901 mixer board 0.15mF capacitor which had burnt out.

Also there are three components hidden beneath shrink plastic tubing on my A701A board, does anyone know what these are and if it is worth just replacing them. Two are white plastic shrunk in series with the Live and neutral supply wires and one is black and connected between the 0.1mF capacitor terminal and a terminal on the motor board.

I think the A701A was made in the 1950/60s does anyone know?

Thanks.

Hi,

I found this on another fix it site.

"The problem is that the load resistor has failed which is common. You would probably need to replace the capacitor as well as that usually fails when the resistor fails. You can replace the capacitor with a 0.1 microfarad 250 - 275V mains capacitor instead of the old electrolytic type. The load resistors are hard to get (hence expensive - about 12 pounds in the UK) I have a few spares. If you want I can supply the 3 components that make up the speed control for A$20 plus postage. These should then last for years. email: wilsonsrus@bigpond.com Note that the KM300 is a different system to the A701A "

The load resistor he mentions I think is 450 ohms, this was from another site.

Hope it helps.
