Blender died ...... motor won't turn on

Check the motor for continuity, it may be open circuit. If it is locate the thermal fuse covered with insulation tape on one of the field windings (where the metal clip is) Check that for continuity, if faulty bypass or replace it.

Assemble it with motor secure and base & feet on. Drill 3 or 4mm hole in edge of coupling Put screwdriver into hole on a large angle and whack the handle to undo the coupling. You are whacking it to turn in the same direction it turns when the motor is running.

This will probably need either a new thermal fuse on the field windings or a new motor.

It is more likely the motor is faulty than the circuit board. Test the motor with a meter.

Take the base off and check the motor for continuity.

you are using your KitchenAid blender and it stops blending, you may think there is a problem with the motor in your machine. However, a common reason for the blades not rotating in the blender is a dirty or faulty coupler. The coupler is what connects your blender dispenser to the motor, and you can easily replace the coupler at any time by only using a screwdriver.
Things You'll Need

• Flat-blade screwdriver

1. • 1 Turn the blender dispenser clockwise and lift up to remove it. Set the blender dispenser aside.
     
   • 2 Insert a flat-blade screwdriver between the black drive coupler and the frame of the blender on the top center portion of the blender.
     
   • 3 Lift the screwdriver upward, and the coupler will start to bend out of place. Slightly turn the coupler and then lift up on the screwdriver again.
     
   • 4 Continue to move the coupler slightly and lift the screwdriver until the coupler is completely removed.
     
   • 5 Insert the new coupler over the blender's motor blade and then twist the coupler counter-clockwise until it is tightly fastened.

More often than not it will need the motor to be replaced, only Kitchen Aid parts will do, motors are usually unique to brands and models. Sometimes it can be the control/button panel but normally the motor.

Does the motor still work if you take the pitcher off of the base? If so, the rod that's in the blade assembly is probably corroded. The blades are connected to a metal rod that passes through a brass tube through to the piece that makes contact with the motor when you put the pitcher on the base. The grease wears down eventually and if you don't pulse and run the motor for a long time at once, the heat can corrode the bar and cause the blade to stop spinning. You can either disassemble the blade unit, or buy a new blade unit online. google blender parts and you can get one for $10

your blade assembly is corroded. take it off, and using a rag, grab the blades. using another rag, grab the other end (probably rubber) and turn CLOCKWISE - it's threaded reverse, so you have to turn to the right to loosen, not the left like usual. I had to clean out the rod that connects to the blades - it was all nasty and corroded. I cleaned it with my Dremel and regreased with a tube of grease I keep in the garage, cleaned all other parts with some Dawn, dried well, reassembled, and works almost like new. I'm guessing I ran it too long without pulsing the motor and the heat corroded the rod that's connected to the blades. OR you can buy a replacement blade unit for about $10 online on a blender parts site

Alternating blinking lights on a Kitchenaid blender indicate a bad circuit board which is unable to run the motor properly. Unplug the blender, take the jar off, and turn the spindle by hand. Then plug it back in. If it does not work properly, try a different outlet (perhaps not in the kitchen). If nothing works, the blender needs to be repaired.
