there should not be any ice formation in the fridge compartment .have you left the door open accidentally ,this would explain the ice inside,pipes for the door dispenser which do carry water do not run over the top of the fridge ,so really there's nothing atop that could leak.the ice build up is most likely due to non closure of the door .check the doorseal for any splits or food debris between the void.the water under the salad crispers is most likely due to a blocked drain,look inside the fridge on the rear wall .you should see a drainage channel that leads into a hole,ensure that this is clear .use a long piece if wire to unblock the drain.they may also be a red plunger in the hole.
