Why does water freeze in bottom of fridge?

I noticed water in bottom of fridge turned to ice. Then saw the back had ice. I thawed the fridge fully. After plugging it back in the bottom ice came back after a couple days.

I am not sure what started the problem. First noticed that fridge wouldnt shut. Cleaned the liner and it shut. Then had to take out bottom drawer because the back froze pushing the drawer forward. Like mentioned i unplugged and thawed fridge but ice is back in bottom. I looked up appliance repairs but apparently no one repairs samsung in my area.

Model RS2520SW

Hi @minnesota1 ,

What is the model number of the fridge?

It may be that the "drain" for the frost melt water (when it is auto defrosted) is blocked.

Also a build up of ice could indicate that the auto defrost cycle is not working or the defrost heater is not working etc.

Is the fridge temp OK (not the freezer but the fridge) or is it warmer than it should be?

Cause 1

Clogged or Freezing Defrost Drain

The defrost drain might be clogged or frozen. If the defrost drain is frozen, the water will overflow the drain trough and drip down to the bottom of the compartment. If the defrost drain is frozen, thaw it out and ensure that the drain is clear of debris.

Cause 2

Drain Strap

Some defrost drains are outfitted with a drain strap. The drain strap is a small piece of copper or aluminum that attaches to the defrost heater and extends partway into the defrost drain. When the defrost heater turns on, heat is conducted through the drain strap to melt away any ice that may have accumulated further down in the defrost drain. If the drain strap is not in place, the defrost drain may be more likely to freeze over.

Cause 3

Drain Heater

Some refrigerators are equipped with drain heaters. Drain heaters prevent the water in the drain pan from re-freezing and clogging the defrost drain. If your drain heater is defective or is not in the proper position, the defrost drain might freeze over.

could also be icemaker tray is bad and not releasing ice properly. I have to replace my icemaker tray every few years to keep it from filling the ice bin up with a solid block of 2 gallons or so of solid ice. You can stop the icemaker and see if the ice accumulation problem goes away. if so you have found the source of the water that is getting in the bottom of your freezer.

The freezer seems to be fine. The ice maker is working normally. The ice build up is in fridge side.

Stopping the ice maker didn’t solve the problem, I tried that and having all the ice out.
