First look at the hinge
Then work out the make of the fridge
Then use google and select IMAGES
Put fridge hinge - into the search box
Look at the pictures until you see your hinge
Follow the link
Alternatively put Fridge Hinge into Amazon - they have dozens of them on offer
Use a screwdriver to make the change
Take the stuff out of the door first.
Good Luck..., June 2016
