samsung washer control board - DC92-01021H

[ajshoe]

Have a Samsung washer - top load that only starts when it wants to. Normally pushing the start button after selecting the cycle - it won't start, just beeps. constantly adjusting cycle and hitting start may get it to work. I took out the control board (wax or gum coated) - don't see anything obviously wrong. Put in another used control board - washer works perfectly (start button works).
Is there a way to remove this wax / gum off the board ( DC92-01021H) ? I'll post pics tomorrow morning.

Most likely bad caps ? I read on another post - bad voltage regulator. thanks

cycle selector might need cleaning

Re: samsung washer control board

appears that all functions work -rotating the knob selects any cycle. the only fault is the start button doesn't start the cycle that was selected. The start button is acknowledge as I hear a beep when pressed. I can get the washer to start but is totally randomly. can't figure out sequence to get it to run consistently.

Good job! where is the cap located? This will help lots of people. The conformal coating is always a pain to remove, yous is more likely to be silicone based conformal coating. Washer model number?

in the pic - it is the cap with the black x on top of it - top of the board (actually easy to remove and install new one). thought I put model # in topic - my mistake. Samsung washer model #WA50F9A8DSW/A2. Is there an easy way to remove that silicon coating ? I spent a lot of time peeling it off.
