I have a 2 year old refrigerator that is a Samsung. The ice maker was making ice cubes 2 days ago. Now when i pit my cup under the ice dispenser and press the cup to the dispenser, it makes a noise like it is trying to put out the ice but no ice comes out. I am not mechanically inclined so I would hope someone could assist with my issue. What the heck do I check to see if the ice maker is broken?
