I changed the door from right to left hinge, but there is a gap at the top of the door, and I cannot figure out how to adjust the door to eliminate the gap.

My guess is that your door isn't level in all sides..or your frame May be off.. Sometimes adjusting the hinges can fix it.hope this helps..

can you unbolt lower hinge from Door and put thin spacer between hinge and door. that should lift opposite side.

Hello Joe;

My name is Peter. I am a retired field service refrigeration technician.

This was your first time setting the gap between the doors. So, I will share with you the various ways to adjust the doors gap.

1.) On the bottom of some doors there are adjustment screws for pitching the door left or right to set the gap. This was a good design idea, but there is not locking nut to hold the setting. Opening and closing the door will remove the setting. So, if you have these adjust screws, we will forget them.

2.) Lets try this: Adjust the front leveling bolts. Loosen the top of the door hinges. If the gap is smaller at the top, lower the leveling bolt up on the left hand side. Turn the bolt counter clockwise to raise. Pound on the doors to free them to adjust. If the gap is smaller on the bottom, on the right jacking screw, raise the jack bolt by turning the jack bolt clockwise. Once again, pound on the door to free for the adjustment. Then tighten to top door hinges.

3.) OK, This did not set the gap. The gap between the door is different depending on the model. Determine the gap which you would like to set. Using something solid like pieces of wood (do not use cardboard it will crush), loosen the top hinges, evenly space the wedges and tape them to the door. Now tighten the top hinges and remove the wedges.

4.) Ok, This did not set the gap. Look on the bottom of the door at the hinge. You have a matching set of grommets. These grommets interlock when the doors close to keep the doors closed. These are high wear components. The doors rest on these components. One grommet set may be more warn than the other affecting the door gap

There are adjustment screws or bolts on the hinge attachments to the oven. Loosen them and adjust the door using wedges to hold the door in place.

Check the lower hinge of that door for a broken closer cam. The upper hinge is adjustable and adjusting the corners in the front will shift the cabinet to align the door also.

Sounds like the top hinge is loose. If the hinge has a cover, remove it then hold the door in the correct position and tighen the hinge screws.

This is a simple job remove both doors and switch them from left to right.You will have to remove the plugs from the holes where the hinge go be sure to adjust the gap between the doors and put the plugs back in the place where the old hinge screws were.
Hope this was helpful.

Top hinges can swing right to left slightly when all 3 screws are loosened under removable cover. Use a 5/16 nut driver. Hinge cover may be phillips, 1/4" or 5/16".However, fridge case must be level left and right first. Level fridge with adjusters behind toe kick cover. Once level, you can adjust gap between doors with top hinge movement. Keep in mind that this is a man-made product and you may not get the doors exactly straight due to lose manufacturing tolerances.

check the alignment of the doors. their is an adjustment on the top hinge. also the hinges have washers on them that you can adjust the door up and down by moving washers to the hinge under or over the door.
if you already checked this and think it is a different problem then let me know, i will help you figure it out.
