My LG fridge freezer GR-L207BQ is beeping and changing freezer temperature on its own. How do we fix it?

on the back wall inside the freezer unscrew the white panel and then remove the panel behind this . you should now see a tray that runs the width of the freezer with a driphole on the left-hand side which will probably be frozen with ice , chip away whatever is possible and then put boiling water on the driphole and once this is clear you should find the problem sorted , 1 other option is to turn the fridge/freezer off for several days and this will allow the ice build-up to thaw thus resolving the problem

I poked a hole in the freezer with my knife while trying to defrost it. Now it is making a constant hissing sound. what should I do? is this dangerous?

well i have the exact same refrigerator but opposite problem.... the freezer works but the entire refridgerator is a freezer....why is the fridge part freezing everything. This appeared to happen after the power went out and the entire fridge is a freezer now.

I have an LG side by side fridge/freezer model GR-L206CVQA.
The display panel locks up and I cannot change the dispenser
