Hi... my name is randy and my question is this... medium speed runs faster than high... wasn't always that way... this has recently happened also with another ceiling fan... there is only a 4 step pull chain and directional switch... I have already replaced properly the 5 wire capacitor send free to me by harbor breeze... also there is now a more robust hum than when it was new.. especially when switching it to the medium speed... I am very well versed in electronics and mechanics so feel free to get technical as I can take the motor apart and try any ideals you may have... if possible I would rather fix it than buy a new one if possible... thanking you in advance for your time and effort to help me... sincerely, randy :))
