Refrig. cant work unless the freezer is working ...all cold in produced in freezer and circulated to refrig. check freezer for frost build up and if fan is blowing, check condenser, make sure its clean, and fan blowing, check vents in refrig. make sure no blockage, controls should be in the middle setting, check make sure compressor is running

SOURCE: Ice Dispenser Doesn't work...

sounds like the water coming into the icemaker is spilling over or leaking into the ice despenser bucket.... check for ice build up or plugging of water chut into ice maker

SOURCE: Water dripping from the water dispenser on freezer

If the water is dripping from the dispenser tube, you need a water valve. The valve is not shutting off completely. Check to make sure water is not dripping from ice chute. If the chute door doesn't seal off you will get moisture there and it will also frost up the ice chute.

One thing that can cause this s the removal of the styrofoam block that surrounds the water reservoir. A lot of people think this is just for shipping but it is necessary to prevent the water freezing.

If it is missing it ill need to be replaced.

SOURCE: Water dispenser keeps freezing GE Refrigerator

If this is a newer model GE side by side refrigerator, this is not uncommon. what you can do to check to see what is going wrong, remove the toe plate at the bottom front of the unit. Under the freezer door, you will see a white plastic water line, with an inline connector about 4-5" from where the line comes out the bottom of the door. this is normally a blue push-in type connector. On this connector, you will see two white sleeves on either side, push in on this sleeve while pulling the corresponding water line section out of the connector, if you squeeze the sleeve enough, the water line will slip right out. Place a towel on the floor, make sure both ends are on top of towel. Now, breifly actuate your water dispenser trigger, see if water comes out the exposed water line. If water comes out, your entire water dispenser system is OK, but, the water line in the freezer door is frozen, in which case the only way to melt it, is to turn the unit off, open the freezer door, and blow a fan for a few hours, to melt the ice INSIDE the door. You could also buy a new door, but that is very costly.
If no water comes out the exposed water line, then either your water filter is clogged, or you have a bad water valve solenoid
