When I first installed my Mark I the blower was run as I got it, but after a few weeks I had to spend some time cleaning the dog and cat fur out of the squirrel cage with a brush and compressed air. I removed the 2 screws holding the wire guard on the intake and fitted a piece of A/C filter over the wire mesh, under the bracket. No problems since, I just vacuum it off when it's dirty.
I also fitted a switch to the connection box, so I don't have to keep unplugging it. I later rewired the wall receptacle to switch one outlet off when I shut the switch off for my through the wall heating scavenger.
The motor doesn't have bearings, just bushings. This is common in small motors that don't run under heavy loads.
