Re: Zanussi Fridge/freezer door problem
You can buy the door seal and replace yourself or get an engineer to change it.(For your fridge/freezer the fridge door seal is available)
Dave should help with the part I imagine.
As for the door dropping sometimes caused by age, over time the cabinet starts to twist and pulls the door down with it, its very hard to reverse this process just make sure it is completly level. A few washers on the bottom hinge of the door will raise the door enough to turn off the light.
***Remember to switch off the fridge before you work on it!***
