I finally got my Whirlpool Duet out of the bulit-in laundry closet and
out of storage as our remodel is nearing the end. The electronics
inside is exactly the same as the one pictured in .... EHam article
follow-on to mine, even though his is a Sears brand.
I checked the control board inside and the one Whirlpool sent me for
replacement, and they are different. But when I swapped them, there was
no noise improvement.
I haven't swapped the front panel board yet. It is shielded on the
inside (box around the front panell board), but I can't tell if it is
shielded on the front yet. There were no internal ferrites, and the AC
filter was roughly the same small one pictured, though different
values.
I have a large Sprague filter to mount internally, so big ferrites to
put on some cables, and some smaller ones to clamp on. I will be
putting the rest of them together as I can, and grounding the whole
thing to a "Ufer" ground that I had installed directly in the new
laundry room.
So, in other words, the two worst offenders we have heard about both
have the same electronics control board. I will report more news at it
develops.
