Your part# AP4044675 electronic control board seems to have a plastic housing around it. Is this correct? Do you have a video on how to replace it.?
Yes the control board does have a plastic casing around it. You would need to remove the main top by removing 3 screws at the top back of the unit then slide the panel backwards to remove. Once removed the control board will be either on the upper right or left side wall of the unit. With the control will just unclip from the side.
