carpet height adjustment: how to properly reinstall?
This seems to be an ancient thread, but not as ancient as my simplicity 7350 (green) which I bought in 1996. The thing performed flawlessly until a year ago when my new wife vacuumed right over the cord on the floor and left it running while she came to find me to say the vacuum was making a strange noise. Circuit breaker kicked in during that time as the roller scraped off all the insulation and shorted.
Other than dealing with the smoke alarms and the fire dept. my alarm company called, I managed to replace the cord and the brushes on the roller at minimal expense.
But the carpet height adjuster just won't go all the way down/inside the housing. Before the power cord escapade, the vac pulled itself into the carpet (medium pile) and made a deep vibrating noise that could be heard in the next county. Anything loose on the carpet surface would dance like drops of water on a hot skillet. It raised the knap of the carpet, the way you would expect to see in a house you were planning on buying and taking a walk-thru.
Now the thing doesn't make any vibration, the roller turns but only makes the occasional diagonal mark in the knap and leaves small bits on the surface (like a sequence or bead, etc.) I replaced the belt a second time and in doing so, triple checked that the roller is properly seated.
I played with the 2 wheels behind the roller that the salesperson told me 24 years ago was part of the "automatic carpet height adjustment." They only depress so far but remain about 3/8 inch exposed above the metal bottom plate. I think this is the problem, but I can't figure out how to fix this. Any ideas, or does someone have a schematic? Must be something I did wrong after replacing the power cord.
I could also use another belt or two and a half dozen sets of the hepa secondary filters (I have plenty of type B main filters as I bought 150 of them 20 years ago, knowing I will have this vacuum for decades, probably the 2nd smartest thing I ever did).
