Why is my doors getting warm at the top - LG LFX25960ST Stainless Steel French Door Refrigerator

The blend door is located at the top of the plenum chamber. The dash needs to be removed/pulled forward to access it.

It sounds like a loose or bad seal on the top area of the freezer door. Use the old dollar bill test to see how good the seal is. Hold a dollar bill up to the seal and close the door. there should be some resistance. compare the resistance between the top and bottom of the door.

check yor damper door, it's the little door at the top and or bottom of the fridge insid near the top and or at the bottom behind the crisper drawer when working right they open to let cold air in from the freezer and warm air out. top one cold in, bottom one warm air out.they work on a sensor/relay when the freezer fan goes on they open when cold air is needed.

Do you have eatc/electronic automatic temp control? The temp blend door, I wouldn't remove that, with no door, it seems to me your getting 50/50 hot and cold. Are there any eatc trouble codes?
Does the engine reach operating temp, hopefully over 200 degrees F. Are the heater hoses hot to the touch?
Do you live in an extremely cold region?

Hello
Check you door and door gasket to make sure you have a good seal. What happens is warm air and moisture is getting in and condensing on the panel. I hope this helps. Please leave feedback. Thanks

Make sure the door is closing all the way. Also check the door gasket for rips. It sounds like warm air may be getting in.
I hope this helps you. Please leave feedback.
Thank you.

If its the door alarm specifically, and not a temp alarm, assuming the door is closed of course check a couple of things. When you say its not cooling, is it not cooling in both sides, one side, part of either or both sides - i.e. top is warm and bottom is cold? My first door alarm thought was its possible door switch is bad, causing both light to stay on and alarm to think door is open. Is it especially warm or hot near a bulb in either side? If its warm at top, I would look into your evaporator fan motor operation, If its not cold on one side and cold on other, that could be several things, too many to list without specific temps.

try unplugging the unit and use a blowdryer to defrost the return air ducts, they tend to freeze up, they are located on the rear wall of the freezer behind the panel. with doors open and unit unplugged, introduce warm air for a couple of hours

1. check gasket
2. check the light switch on top of the refrig. section. If then pushed the switch turns the light off, but the light is still on with the fridge door closed - door needs adjustment.
   

Not sealing. warm air hitting cold air causing frost. also, door frame heater may not be working. most frames are "warm" to the touch. normally called an "anti sweat" heater.
