Can you say if it’s possible to get hold of the flat brown ferrite section of the inside door seal of the Sharp R7260 door. I know the oven is 21 years old but it still works and seem wrong to get rid of it for the sake of a door seal.
It’s probably obsolete but I would urge you to take the microwave to a specialist to have it checked for safety, that isn’t a seal as such, it blocks microwave energy from escaping so if it’s damaged, stop using it straight away please ! . 😯
