To protect the board, be sure to put heat-sink compound on the back of the new circuit (phase) board to ensure proper heat transfer to the housing.

If the mixer gets locked up, can it cause the circuit board to go bad? Mine jammed due to a bad gear, now the motor won't run. I have juice to the board. Any suggestions?

hallo,

meine KidchenAid sagt seit heute nichts mehr. Es hat einmal geknallt und die Sicherung ist raus geflogen. Als ich den Elektronikdeckel hinten aufgeschraubt habe kam mir eine kleine Rolle auf einem Federdraht entgegen geflogen. Ich weiß nicht wo sie hingehört. Kann sie hier auf den Bildern nicht entdecken. Kann mir jemand sagen wo das Ding hingehört?

Danke Christian
