This is as the title states a fridge tutorial (it doesn't cool food just stores it) I dont know if there is another tutorial on this but I hope it helps you make a fridge.

OK Lets start.

First dig blocks in a 3/5 area like this:
L=Leave this block alone. 3=Dig this block three down 2=Dig this block two down 1= Dig this block one down

LL2
LL3
221
2LL
222

Now in the one three deep spot place a sticky piston facing up.

In the one one deep hole place a dispenser pointing towards the two L's ( not the group of four) or downwards on the diagram.

Now in all the two deep holes except the one in the very middle of the diagram place Redstone dust.

In the hole in the middle place a Redstone repeater facing the dispenser.

OK Now cover it all up with whatever block your using (only place one block on the piston) now all you should be able to see is a one deep indent (where the piston is) and the dispenser.

Now on the dispenser place two iron blocks. (any block works but seriously when was the last time you saw a cobblestone refrigerator?) then place a iron door backwards on the side that the dispenser is facing.

Now in front of the door (or should I say behind?) place a pressure plate (wood or stone it doesn't matter much)

So now we have a hole where the piston is and the fridge right next to it. Now you need a lever place it on the spot that that random Redstone dust is next to the piston.

Now load the fridge and flick the lever the piston should come up and the block on top of it will block the dispenser.
Now step on the pressure plate and the food will come out!

Thanks for looking please diamond if this is helpful. (i know a fridge isn't the awesomest thing in the world but oh well)
