Oven door recently has been a little bit stiff to open beyond an inch or so of opening, and now won't open beyond those first couple of inches!? I think it's the right hand hinge that seems to be holding it back more than the left but how can I get to it to check / repair / replace the hinge if the door won't open more than a hand-width? Any advice would be much appreciated.
