Ice is building up at the bottom of freezer, thawing out and then water is leaking out of the door onto floor.

Defrost drain is clogged with Ice and debris. Thaw and clear drain.

THE PROBLEM IS WITH THE AUTO DEFROST (IF THE FEATURE IS AVAILABLE) OR ELSE YOU HAVE TO MANUALLY DEFROST IT REGULARLY

sounds to me like a bad door seals causing condensation and leakage

It sounds like the defroster is not working. Look up online for solutions that are posted.

please check your ice maker to make sure it is not jammed up water can leak into fridge

Is the water leaking from the door, onto the floor in front. If so, probably a blocked drain outlet or pipe. At the bottom rear of the unit, mine had a drain pipe blocked with a plug of mould (5/6 years old machine), apparently quite common. I detached the pipe and cleaned it out and replaced it.
From inside the freezer, I removed the lower back panel and thawed the ice build up on the drainage tray below the defrost heating element, leading to the pipe outside. The puddles of water that was appearing every defrost cycle have now stopped - permanently I hope. Hope this helps you

Hello, this sounds like you have a blockage in the drain tube, remove panel back/bottom of freezer..you may see ice build up...melt ice with hair dryer/heat gun...you will see a pan below evaporator...melt ice in pan...dry water up in pan with paper towel...now you should see a hole in pan that leads to drain tube...pour some hot water in pan..wait a couple minutes..mop up water and repeat this step 2-3 times....once you have done this find some flexible curtain wire or electrical wire..poke down the hole until you see the water drain..now it is clear..put back panel back and you are good to go. The reason you see water in the fridge is because the water has been leaking into the freezer and down the vent into the fridge instead of running into the drain hole...Please feel free to comment again if you need any further assistance.

yep, total defrost is the 1st thing to do. if you want to speed the process, see the following page how to do is good luck

Your problem is possibly one of two things. The ice maker is leaking or the defrost tray behind the rear panel inside freezer back wall is clogged with ice or something else. If you know its not the ice maker unplug the refrigerator and remove the back panel to see if the drain is blocked there, Let me know, Sea Breeze
