i'm not sure exactly which model was wdancer but mine was the k5 if i remember correctly.
as far as i know all of the kitchenaid mixers use this same scheme but the boards have varied somewhat over time
update ...
i found another mixer that i borrowed from a friend.
so you can look at the schematic of the board as wdancer posted and his values for resistors
here are his missing values:
C1 is the 0.1 uF
C2 is 0.022 uF
as a side note, 0.1 uF is sometimes listed printed with the numbers 10...
wdancer, thanks
i did think of 1 other point of data
the 0.1uF was rated 100V, the 0.022uF was rated 400V
i haven't been able to wrap my head around the circuit enough to see if this is a clue, but if it is, then i would think C1 is more "exposed" and the voltages across C2 would be more...
yes, i wasn't expecting the caps to be glued to the triac (the leads of the cap pulled out of the body
then my wife didn't recognize the small rectangular boxes as something of interest so they got thrown away
a bit of murphy's lay going here
i am thinking the .022uF goes nearer the triac but...
kitchenaid phase control board schematic
my phase control board has 2 film capacitors: 0.1 uF and 0.022uF
when i pulled the triac out, the caps came with it (they were glued together)
i got replacement caps, but i am not sure which is which (i.e. which value would be closer to the triac)...
