Ice Dispenser Frosting up

This is caused by air leaking past the seal in the shut door. Push in on the paddle and release and watch the door shut close. It should make an air tight seal. You can also shine a flashlight in the shut and look at the opposite side to look for light.

Are you sure your model is the GSL25JFTBS? Sounds like the ice dispenser door is not closing all the way and allowing air and moisture to enter via the ice door. Items 62, 63 and 36 in the photo HERE are most likely broken and causing the frost. You will need to open the dispenser to see just what part is broken.

I am here should you have questions or a different model number Thanks Sea Breeze

HI MAUREEN. i reckon u have left a spring off or the flap pivot pin out of place.start all over again and try.good luck.ali

You have a duct door problem. The most common is the seal on the door goes bad or the pivot on the dispener can break off. Both allow warm air inside thus your moisture. I hope this helps.

Warm air meets cold air for frost/condensation. Flap may have stuck open or not sealing well. clean out and check seal/operation bucket removed if in door.

Try to take some ice from the dispenser. Remove the glass and open the freezer door to look down inside the dispenser chute and see if the trap door has re-closed. If it remains open warm, humid air will enter the ice bucket and gradually freeze the cubes together. Trap door remaining open is generally caused by a rusted electrical coil which pulls the door open electrically then sticks, unable to re-close. Coil is located behind the panel that operates the dispenser. Relatively easily accessible.

Replace the defrost clock.

Most likely the ice door is not closing properly.
Clean out the ice chute and look down it from the inside while you shine a flashlite up from the outside. If you see light around the door then it needs to be replaced or something is wrong with the mechanism.
Post back and let me know what you find.

Open the freezer door and look down the ice chute while you shine a flashlite up the dispenser cute from the outside. If you see light around the chute door, it needs to be replaced or something is wrong with the mechanism. The problem you describe is almost always air leakage around that flap.
Post back if you need more help.
