thats exactly what I did but i found that because the back of the rubber seal does not sit flush using the white board as it does with the actual door it cause the rubber seal on the side of the door with the hinge to contact the fridge first so that it doesnt contact the fridge for all parts of the fridge at the same time and puts just enough stress on the top part of the door opposite of the hinge to prevent a 100% seal. I am not sure if i can move the hinge to the other side and it is just something that is coming up with one side of the door or the other but I am not getting a full seal. Did you screw the board down as tight as you could get? When I go to close the door if you close it slowly and listen carefully you can hear the creak of the rubber contacting the fridge and being smushed with the door still open 8 inches or so. The easiest way to tell is when it is dark let the fridge light come on and see if you can see light coming through
