for the future, definitely stronger magnets will solve your problems, With 6 1/2 in magnets in your current project, it must weigh a half pund, and only have a bout a quarter pund pulling force. with the rare earth, you will get double the force from a single magnet the same size and weight as one of your current ones. as far as saving this project, the only thing I can think of is to it over so those screws catch the top of the fridge door, and the magnet just holds it against the door. you arent going to get much more friction against an enamel or stainless door than you are getting with silicone.
