Blown Resistor on kenwood A901 Chef?

The above answer is a little misleading. The resistor connected to the triac trigger should be 220 ohms (red-red-brown). The gold band refers to the tolerance. In practice the value is not very critical. The other resistor seems to be 56 ohms but calculations of the peak trigger current suggests that it could be higher. I used another 220 ohm resistor in that location and that works fine.

As you spotted the reason for that resistor blowing is that the capacitor becomes leaky so it should be replaced at the same time.

(1) Search this website for "Kenwood Chef A901".
(2) JS's answer to question "How can I fix my kenwood chef model A901?" gives component values.
(3) The colour code of the larger resistor which JS gives as 220 (no units) is red-red-yellow-gold, which I read to be 220 KOhm.
(4) On my machine the small resistor was burnt out but I have replaced it with a 56 Ohm 1/4W as listed by JS. The replacement has colour code green-blue-black-brown(or gold)-red. The machine is working again so far.

Hope this answer is OK
