How to Replace the Potentiometer

Tips on disconnecting pins at the 18-pin connector


  • On the connector, locate a small space at the top-right of each hole (note that each slot is not a perfect square but instead has a little cutout at the top-right).
  • Insert the pin removal tool into this space, sliding it above the locking tab on the pin.
  • This depresses the locking tab on the pin, allowing you to gently pull the wire out with little force.
