Hi folks
I decided that I was not going to pay £72 for a new freezer door especially when I hardly use the freezer and it is only the seal that needs replacing.
Sourced a genuine freezer compartment door seal Ref 25-05099-31747 from E Bay for £7.31 which was slightly over size, which allowed me to cut it with a stanley knife whilst retaining all corners. I used Loctite All Plastic Activator and Super Glue . Left fridge on gas overnight and seems to have stayed in position. Thought it was worth the gamble. Quite a simple job really.
