Lay the door down on a padded flat surface while be- ing careful not to allow the lower hinge plate and mechanism stem to slide out the bottom of the door.
NOTE: The lower hinge plate is under spring tension (see figure 15). Grasp the lower hinge plate. While keeping a firm grip on the plate, carefully slide it out the bottom of the door just far enough to allow the plate to rotate a full 360°. Unwind the tension of the spring by carefully allowing the hinge plate to rotate a full 360° several times.
VI. a - REHINGING THE DOOR (cont'd):
To reinstall the door, position the lower hinge plate into the position of being open 90° to the cabinet. Place the top hinge plate pin in the hole in the top of the door and support the other end of the door for minimal movement.
Start the bolts in the lower hinge plate and tighten the bolts enough to hold the door in place. Remove the block from under the end of the door. Adjust the door as outlined in section VI. c.
VI. b - PREPARING FOR EXTENDED SHUT DOWN: If the refrigerator is not to be used for an extended period of time, disconnect the electrical power supply and open the doors. As soon as the cabinet has warmed up to room temperature, wipe out the interior. Leave the doors open and check again to make sure that no moisture has collected on any parts. To restart refrigerator, follow instructions under PRESTART CHECKS and OPERATION.
VI. c - ADJUSTING THE DOOR:
Occasionally the door(s) may require alignment adjustment. To do so, first open the door and loosen the hinge plate screws enough to move the hinges if desired, but the door is held in place. Center the door in the opening. Next level the top hinge plate and tighten the screws. Finally, level the lower hinge plate and tighten the screws (see figure 16).

VI. d - DOOR GASKET(S) REPLACEMENT: Remove the old gasket by pulling it out from the gasket retainer. Next, install the four corners of the new gasket by pushing straight in on the gasket until it is hooked behind the gasket retainer. Be careful not to stretch the gasket as it will not return to its original length. Starting at the center of one edge, push the door gasket straight in until it is hooked behind the gasket retainer. Proceeding from this point out to the corners, continue pushing the door gasket straight into the gasket retainer. proceed doing the same to each of the remaining edges until the gasket is completely installed.
