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 --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

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 Has anyone diagnosed the problem with the ETC on a kenmore dryer?

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!
