This is generally due to some force of resistance on the impeller,
usually friction between the impeller and the impeller shaft or the
impeller blades
and the plastic guard which sits above it. If you gently touch the
impeller bade with a plyable object that won't do damage to the
plastic blades, it should spring to life.
============================
That's exactly what I do! :-) I move the intake over and give the
impeller blades a little nudge with a piece of plastic from a Q-tip.
I have noticed if there's a lot of slime on the impeller and impeller
walls they wont start themselves either.

This problem happens a lot less often if you regularly clean the impeller,
shaft, and motor well.

You're right. I should do them more often. I squeeze out the sponges every
week or so but only clean the impellers/wells once a month.

My AC motor cleaning kit consists of a pipe cleaner brush and an old tooth
brush. I remove the impeller and clean it with the tooth brush, then yank
out the impeller shaft with a pair of pliers and clean it with a soft rag
or paper towel, then I clean the inside of the motor well with the pipe
cleaner brush. I suppose a very fine pipe cleaner would work well to
clean
the inside of the impeller magnet and remove any metallic fray from the
inside of the magnet, but I've never found it necessary to spend the time
trying to obtain one fine enough to fit.

I'm not that particular. I also use an old toothbrush to clean the magnet
and blades, but a Q-tip to do the well. I don't remove the pin or shaft.

Cleaning the motor regularly also cuts down on the wear and the amount of
noise the AC filters tend to make after operating for a few months.

I don't doubt that a bit. I've been fortunate in that only one of my ACs
has an irritating grumble. It's in the sunroom so we're not bothered by the
sound.

I do partial water changes twice weekly. I look at the water flow out
of the filter. Slow flow is the signal to clean the filter media. If
the flow is still slow after changing the media, I know I need to
clean the impeller, magnet and motor well. Good time to check the
intake plumbing as well.
