Open the doors fully so the bins and the doors themselves don't obstruct the shelves when you pull them out.
Pull out and remove the produce drawers from the refrigerator first if you are removing the shelves that sit directly on top of them.
Hold onto to the front of the shelf with both hands.
Keep one hand on the front of the shelf as you move the other hand underneath the glass to the middle of the shelf.
Support the glass, and use both hands to tilt the front of the shelf up.
Pull the shelf forward to release it from the shelf hooks, and then pull it out.
