Ice build-up on the inside top of of freezer door
Yea def , not normal, nor an acceptable amount of ice forming there( good pic). heres what i have been told to try and with good results
first make sure the door gasket is sealing all the way,(small gaps in ht emagnets at extreme corners) is common but with a little amount of "mortite"or "permagum can sometimes be insterted behind the corner of gasket to assist filling the void.
second a small amound of a white/clear silicone be applied to the outer perimtere of gasket, to minmize air movemnt from between gasket and door panel.
lastley in oyour second pic i see "frost free" written on a plastic air deflector. you can remove that with 3-4 screws on backside of it, and then reinstall with a small spacer so as the baffle now with sit with a 3/8in. gap between it and the top of the freezer liner.( a brass ferrel from the compression fitting of a plumbing fitting is just the right size)..... the theory behind this is to prevent the air from gatting "trapped" in the void created when the door closes-- air can now pass back and forth freely.
I hope this gives you some satisfaction if not I would advise another tech be sent who is willing to call for factore tech support( ths is where i got my info from) Read More At : 13.7 cu. ft. Upright Freezer GLFU1467F...
