Why have blades in carafe stopped turning easily?
I have a K-TEC Champ HP3 blender. Counter shows I've used it 187 times. For some reason the blades in the carafe have become stiff and won't turn easily causing the motor to sound very high-pitched when I try to use it. It worked fine the last time I used it which was less than a month ago. Tried 3-in-1 oil and doesn't help. Any suggestions would be greatly appreciated!
Thanks!
