You're probably right about "mist chamber" containing the element.
However, at $52, I'm not interested.
Besides, I'm now generally down on Sears customer support. I doubt if
I will purchase from them again.
BTW, I just found a unit on ebay, made by Holmes. Pretty similar to the
Kenmore unit except it comes with a FIVE year warranty. That's almost
unheard of, in view of the short life of these systems. AND, only
$29.80 + $7.95 for shipping, brand new factory sealed. I read a review
somewhere on this unit, and it was favorable.
