Thank you for using Just Answer.
If you have lost the board again (burned resistor visible again), then I have never had someone do the repair to the board. These are always replaced without exception.
However, if you have the training and are able to test the board (and/or replace the burned resistor) then it would be worth trying since the board is gone anyway.
Do you see a burned resistor again?
Check the door switch by first "playing" with it to see if mechanically it will malfunction. Oh yeah , and you DO want to unplug the washer so that you do not blow another board.
Then, if you can not get it to malfunction mechanically, check it for resistance (after you remove it) and voltage (after you plug the unit back in). You probably do have schematic for the entire washer to verify voltage.
I am not aware of any control board schematic available. I believe the service manual will instruct to replace entire board only.
Chuck knows this issue well and has provided great infomation for you to avoid losing another board. The door lock wax motor can work intermitently and then short out again.
You can also fix the boards you have. He has had positive results in doing so "in a pinch".
Thank you Chuck
