Frost build up around ice dispenser in freezer

Check your freezer door gasket is sealing properly.

I have this problem as well, only nobody is leaving anything open. The defroster is defective of these things and the duct between the fridge and freezer gets frozen over and the cold air can't get in the fridge, so the freezer keeps working until it's blue in the face.

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

This is usually caused because the door is not shutting all the way or not tight allowing air in.
There is a solenoid that operates the door that could have stopped working. Can you hear it?
The hinge on the door could be broken or the bracket it goes in could be broken. You'll have to look to see what's wrong.
Remove the dispenser cover by gently prying starting at the bottom going round and round a little at a time to prevent from breaking it. When it's off the screws will be exposed to access the other components

This sounds like your ice may be melting and freezing around the chute. You may need to replace that rubber gasket on the chute. Otherwise, if you use a lot of crushed ice, that will build up badly on the chute and you can manually clean that off. I hope this helps you!

Replace the defrost clock.

well check to see if door seal is split if it is get new one!! need to see photo of the frozon over dispenser- found before that when ice not bein used alot the odd time you will have to take out the ice in the bucket crack it up and put back in try this???

first check would be to see if the flapper door is closing all the way in the dispenser area. best way is to remove the ice bucket and shine a flashlight from the front up into the disp door area and look for light around the door from inside the chute.

another check would be to make sure the door delay mechanism is connected an not allowing the dispenser door to close to fast trapping a cubes in the door and causing an air leak in the chute..

Keep in mind if you use alot of crushed ice frost build up is faster than with just cubed.

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.

Is your fan blowing in the freezer? Frost on the back wall of the freezer usually indicates a defrost problem... defrost themostate, heaters, take back panel off and check evap for frost build up and if your fan in working.
