Black and Decker BL3900 stopped working
I had the same problem with BL6000 model. After using the blender few times it went dead, though on occasions it ran for a couple of seconds or so. I opened the base and saw the red light come on and off in response to pressing the buttons, but the blender would not run. I checked the connections and resistances across various points, and then decided to bypass the digital control panel by joining the blue (AC) and black (motor) wire terminals, as the control panel must be altering the frequency or voltage going across this connection into the field coils (and also to rotor). The motor is rated at 120V. The motor ran perfectly, though i let it run only briefly, confirming that it itself is all right. I think one must check a step further by studying the current and voltage characteristics to ensure that the motor does not consume more than rated 550 watts if you do not wish to buy the digital control panel ( part number BL5000-01-01, available through partstore.com or black and decker partner site. It should fit BL6000 as per partstore.com). The motor seems like an univeral motor. If anyone knows more about motors and has the same problem, then pl let me know if bypassing the digital control panel and using an external switch to shut the motor on and off is a good idea (digital panel and shipping will buy an equivalent blender in stores, about $18). I am afraid that if digital control panel does not let unregulated power be delivered to the field (and rotor) coils, then one may be putting too much power into the motor and it may burn out prematurely.
