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?
