couldn't find anything about this on site or google so throwing it out there to see if it happened to anyone else. i have a dayton shaded pole motor on my blower and speed is controlled by a plug in rheostat. if i set the speed at about 3/4 it runs at constant and expected speed for a minute or two then unexpectedly speeds up to max all on its own. it works fine at lower speeds but i avoid setting it anywhere near the 3/4 mark before i leave the house because i worry about this runaway speed control. i tried replacing the rheostat with one from the neighbor and the same thing happens so apparently it is something with the motor. anyone else experience this phenomenon?
blower motor surging?

i have a multi tester but i don't know how i would check the voltage. the blower plugs into the rheostat which plugs into the wall. there are no wires exposed. ready to learn something new if you want to teach.
