Hunter Ceiling Fan: variable power switch on wall on High, pull chain on High but the fan barely turns. Oil OK. Have to give blades a push to get them to turn but once turning, they move at the slowest speed possible. Any ideas for what to do?

What model Hunter fan?

When you bypass the wall switch, how does the fan behave from the pullchain?

When you spin the blades by hand, how long do they keep spinning for?
