Kenmore Eliter dryer electronic control board repair
 

Has anyone diagnosed the problem with the ETC on a kenmore dryer? (dryer
runs when start button is pressed but stops when button is released) I'm on
my third board in 3 years. I would like to repair the board. Have checked
all items on component side of board but not on surface mount side.
Thanks Roy

I repaired the board. I have 2 bad ones to work on.
This post is the only one I found on the net about repairing this board. I
am surprised since there are plenty of posts about this board causing
problems.
Here is what I found wrong......for the next guy who has this problem.

board 1:
all zener diodes, D2-D7 were shorted. replaced (1N4738A 8.2v zener)
C2 had high ESR. replaced 220/63v

board 2:
Zener diodes, D2-D6 were shorted. replaced (1N4738A 8.2v zener)
D7 was open. replaced (1N4738A 8.2v zener)
C2 swollen and leaking. replaced 220/63v
C25 swollen and leaking replaced 333/63v
R2 burnt open. replaced 4.7k 1/2 watt
Q2 shorted. MPSA56 replaced with NTE159

Hope this helps. Roy

I am also looking to repair that circuit card. I am looking for a
parts list...R2 is blown completely off the board (the large resistor
under C25). Could anyone look at their board and tell me what the
value of that resistor is?
Thanks!
