GE freezer (side by side) if forming ice at bottom of freezer. The problem is unrelated to the ice maker and water feed (have them turned off), and appears related to the heating element causing water to drip, where it re-freezes at the bottom of the freezer. Any ideas how to fix? Thanks!

Sounds like the ice maker is allowing too much water in to the tray. There is an adjustment screw under the front cover of the ice maker. A 1/8 turn at a time counter clockwise will shorten the time the water delivery solenoid is open. It is possible that something foreign is keeping the solenoid valve to stay open too long, so it should be inspected too.

Remember there are two sides to a dual water control valve, the water to dispenser side and the side that feeds the ice maker. Replace the WR57X10094 Dual Water Control Valve and I think you will be good to go on ice, Thanks Sea Breeze

Try defrosting it completely then re start it again. Shut off the water suplly. Maybe the service guy forgot to turn the water supply off.

Possibly the inlet valve.  If it doesn't shut all the way off it will drip water which will freeze in the chute and cause it to overflow.  

Because the sheet of ice is forming on the ice maker first it leads me to believe the water control valve for the ice maker is leaking water into the ice maker when it should be off. A filter installed before the dual water control valves would also be helpful. If you could find the model number of your refrigerator I would be able to tell you the part number. Sea Breeze

First we have to determine if the problem is a faulty water valve. Reason: faulty water valve can continue to supply water even after the IM or door dispenser is finished calling for water causing a drip feed freeze up problem, or water overflow condition in the ice maker (IM). Another common cause is unrelated, but caused by a blocked drain line often resulting in thick ice build up on the bottom of the freezer, water dripping onto the floor, or water dripping into the refrigerator (top freezer mount models only) and freezing near the lights or damper ducts after defrost. Fix for this problem is to remove evap panel and clear freezer drain line with hot water or compressed air. If this is not the case, and water is dripping out of IM supply line, remove IM H20 supply line from IM at back of appliance and see if the water seems to drip out, if so, replace the water valve. If water doesn't drip out at all, replace IM, or IM module depending on the model of refrigerator that you have as contacts in the IM are also responsible for calling for H20 supply. You will have no more problems after this.

I have had the same problem with ice forming. I found the problem is from the ice maker. The water fill tube delivers water to a plastic piece that acts like a funnel. The water goes through this plastic piece into the ice maker. Ice forms in the plastic funnel piece causing the water to overflow into the ice bin and freezer.

Water accumulation in the freezer more commonly points to the ice maker. Over a period of time, water entering the ice maker can slowly freeze to the point it provides a small restriction and prevents a portion of the water from entering the ice maker. The plastic spout/tube could also have either cracked or shifted and is allowing a small amount of water to leak into the freezer.

In back of the refrigerator behind a removable panel you will find a hose going into the drain pan under the refrigerator. Check and make sure there is no obstruction in the hose which would back up water into the freezer. After the drain hose is cleared the freezer should be defrosted and ice cleared from the drain area in the back. You can direct some hot water with some bleach in it through the drain to insure it flows into the pan.
