Water dispenser in the door did not work

Shut off power and water. Removed cardboard cover with nut driver. Removed old solenoids with ajustable wrench and nut driver. Water inlet fitting could not be tightened because fitting did not allow for lenght of copper tubing beyond ferrel (maybe that's not what it's called). Cut 1/8 inch off tubing and then everything then went together easily. Tested and eveything was good on first try. Replaced cardboard cover with the nut driver.
