user serviceable parts!

[zwol]

I've ragged on Kenmore brand products here before, so it seems only fair that I praise their model 85254 air filter for its easy disassembly: all the screws are the same, there are no snap-together joints, there are no inaccessible or even hidden screws, there are a sensible number of internal components (three), and all wires go through plug blocks in sensible places. They get only two demerits, one for use of self-tapping screws into plastic (a perennial complaint) and one for the design error that made me take the thing apart in the first place, viz. the fan rotor is secured to the main drive shaft with one hex nut and no lock washer. I should, perhaps, go buy a lock washer.
