Broan Range Hood model #AP100-A installed for a little over 2 years now. Was working fine, then....

fan motor got to the point where it would not spin up on it's own without my reaching in and giving the squirrel cage a bit of a hand spin.

This range hood has a variable fan speed dial(see photo below).

This is just a household kitchen. No major grease/gunk buildup on it.

So I order a new motor from Broan directly. Got it the other day. Installed, no problem. Old motor and new motor have all the same wiring, same label, same part # etc. Only one electrical connector which can only connect in one orientation.

Turn it on, high speed works.

Turn the variable speed dial down lower, nothing happens. &%$#%!

When I rotate the speed dial all the way low, I can hear a SLIGHT change in sound and maybe a VERY slight change in motor rpm, barely noticeable.

So what is the real issue here? The variable speed worked perfectly before.
