hi,
customer has asked me to fit new outer door to her single oven, no worries easy peezy.
i went to do the job today and i can’t see how the top of the outer door fits onto the inner door.
the lower part is obvious , 2 screws hold the outer door metal bracket to the inner door.
handle, again obvious, 2 screws.
but the top of the outer glass has 2 x metal brackets on it but i can’t see any where on the inner door to screw them too.
it’s as if there should be a bracket on the top of the inner door but there isn’t one.
has anyone got an exploded diagram or advise for me please.
cheers.
john
