[TenTec] [RFI] Whirlpool Duet RFI

[Robert & Linda McGraw K4TAX]

Basically the Whirlpool Duet and Maytag Neptune use the same technology to 
control the motor.

Neither of the companies will do much if anything to solve the noise 
problem.  First, they don't perceive it as a problem.  If the machine washes 
then it's doing what it's designed to do.  They have enough business keeping 
them doing just that.  Anyway, both designs came from Europe.  And they make 
"like" machines for other companies under names like Kenmore etc.  The issue 
of "quiet" refers to acoustic noise while it's running.  Nothing to do with 
it electrically.

The solution today is for the user/owner to install ferrite on the power 
cords, as close to the machine as possible.  Make as many turns as possible 
on/through a donut.

Personally, if I had the problem today, I'd order a couple of big donuts 
from Amidon, 2" OD x 1" ID x 1/2" thick,  put them on the power cord by 
winding several turns and go back to hamming.
