can i lay my electactic mini fridge on its side to move it?

No, you can't lay it flat. Here's the right way to move it. First, empty it completely. Secure all loose shelves inside with painter's tape. Turn the adjustable feet up to the base. Tape the door shut with painter's tape. Keep it upright during transport—never tilt it more than 45 degrees. Protect the exterior with a blanket.
