Deleted your other post in General Enquiries, best to keep to the one thread. đŸ˜‰
Personally, if the instruction manual says max load is 6kg and you do fit your 7kg door panel then any subsequent damage to the door or hinges will not be covered by manufacturers warranty.
But will it make any difference to the door closing it’s only a couple pounds over the handles on are quite heavy as there’s two solid stainless steel (door plus drawer front) could maybe put lightweight handle on .? I did not realise when I ordered that doors could be a problem
If the door is too heavy then it can slam down, the springs and ropes in it may not cope and over time they will break sooner than might otherwise be expected also.
