Hi - I have a fridge built into the kitchen units. The outer door is part of the kitchen paneling whilst the inner door is part of the fridge. The inner door is attached to the outer door which in turn is hinged (3 hinges) to the inside of the housing cabinet. The bottom hinge has started not to work correctly and I guess I need to replace all three hinges. The hinges seem to be a little different to normal kitchen cabinet hinges - they are flater and also have a little white peg used to align against the main body of the fridge. Could anyone recommend where I could source these hinges from please? Thanks
