Frequent frosting over

The door flap which releases the ice , on the door , is not closing completely .Usually this is caused by a rusted plunger so both the solenoid and plunger will have to be replaced , These parts are located behind the dispenser board so be sure to remove the top freezer door hinge cover and unplug the plug there , to remove all power going to the door , before attempting this repair . I think the part number is WR62X10055 for the kit .
When it doesn't close , it lets warm air into the freezer and causes frost on the dispenser AND on the ice bin outlet . Also , using 10 glasses or more , of crushed ice a day can cause this .

this can be of some help.. http://techie-doc.blogspot.com/2010/09/fixing-refrigerator-problem-frosting-in.html

Sounds like the flapper is not shutting completely. Open the door and look into the door flapper hole from the inside. If its not closed its either stuck (push closed from outside) or broken. If broken you will need part replaced

you are still not getting a seal on that flap. It sounds as if it may be warped. THe reason the frost and ice is building up is due to the flap not sealing there isn't any other reson for your problem. Good luck on your repairs

I had the exact same problem. My neighbor has the same refrigerator, and told me that there is a solenoid in the door, behind the panel where you select between water, crushed or cubed ice. You can carefully remove that panel to expose the solenoid, which is on the right side of the dispenser water line. I have the model GE GSS25. The plunger on the solenoid gets rusty buildup on the outside of it from the moisture and water splashing from the dispenser. You might try wiping the exterior of the solenoid, and working it up and down so that it moves freely. If not, it's a cheap replacement part you can order from GE. The solenoid shuts the trap door which opens when you get ice from the dispenser. If the solenoid plunger does not move freely, then the trap door hangs open, and warm moist air enters the freezer through the ice shute, causing frost.

The frost build up is blocking the flow of cooling air from reaching the refrigerator section. If you take the cover off the frosted area and melt the frost off with a hair blower your refrigerator will work fine for a few days to a couple weeks, and then the problem will show up again. You need to determine why it is not defrosting by itself. You do not list the model number or even an aproximate age of your unit, so I can not be very specific with a solution. Test the defrost heater and then look at the defrost control timer. Also, look for any signs of air leakage into the refrigerator, such as a poor gasket (look at the bottom of the fresh foods gasket in particular) or a dispenser area if your model has a through the door ice dispenser.

Generaly the control board controls everything sometimes you have a bad thermister GE has a help line I beleive it costs 20.00 bucks but you will need a meter and know how to use it and they willl talk you thru the repair .
