The Superba line of refrigerators from KitchenAid features side-by-side swinging doors. When closed, the doors should be the same height. This is usually not a problem, but if for some reason the doors were installed incorrectly, one door could be higher than the other. Fear not, as the doors can be adjusted with just one tool. Because refrigerators can flex, it is best to make these adjustments with the refrigerator sitting level and with a normal load of food inside.
Close the doors and look at their alignment to determine if one is higher than the other.
Kneel down and look at the adjustment bolts located under each door's lower hinge to determine which door to adjust. If one door's adjustment bolt has more of the threaded area sticking out than the other door's bolt, the one with more threads exposed is the one that needs adjusting, as it is too low. Conversely, if there are barely any threads showing, the door is probably too high.
Turn the nut on the adjustment bolt with a 5/16-inch wrench. Turn the wrench from left to right to raise the door, and from right to left to lower the door.
Look at the doors again to see if the adjustment was enough. Depending on the degree of misalignment, you may have to adjust both doors.
