An old broken, torn or cracked seal is relatively easy to see as a problem as to why your fridge is not keeping cool, but a poorly aligned door can be invisible to the fridge owner if you are not aware that the seal is not adhering to the face of the fridge because the door has dropped. What to look out for is when you close the fridge or freezer door the door will bounce off the face of the fridge and may not close. Alternatively you may close the fridge door and the freezer door will bounce open.
A door alignment is a simple process of taking off the fridge and freezer door and realigning the door to the face of the fridge and tightening the screws. We always check the door alignment after replacing seals to make sure the seal has got the “happy slap” sound as it closes.
