I've tried one that is labeled 0, 1, 2, 3, 4.

0 = off
1 = high
2 = slower
3 = slower still
4 = slowest

I also tried a rotary type where as I rotate it clockwise out of
the off position, it goes to high speed. As I continue to rotate
it further, the fan runs slower.

This runs contrary to every variable speed adjustment I've every
seen for fans. I'm worried that there may me another issue (bad
wiring, fan problem, etc.).

That's the way ceiling fans are made. I've never seen one that
didn't work this way. The pull chain on the fan body uses the same
pattern. I don't know why. It's always bothered me too.

I believe because the motor may not have enough torque on the lowest
speed setting to start the fan if you just switch it directly to the
lowest speed, but briefly passing through high speed will get the
blades spinning so the motor doesn't burn out.

That would surprise me. You can leave the fan set on Low, then turn it
on and off with the wall switch. I've done this with every fan I've ever
owned, and none of them have had a problem. Low is the right speed for
me most of the time.

I used to sell ceiling fans, and I was never trained to tell customers
to start them on high. Of course, that's no proof.

I can't tell you how many fans I've installed over the years (billions
and billions?), and I've never had a call-back because a fan burned out.
I HAVE, however, seen some that have worn out from old age and constant
use.
