Why is there ice building up in my freezer?

Question

I have a freezer/refrigerator combo, with the freezer on top. Ice is building up on the bottom of the freezer. What is causing this? How do I get it to stop?

Answer 1

You could have a problem with the thermostat being turned too low or not working. Otherwise a fridge does build up if it doesn't have a fan fitted like in the frost free fridges.

Answer 2

Poor seal around the door.

Answer 3

Defrost heater has failed.

Defrost timer has failed

Defrost thermostat(terminator) has failed.

One of these 3. Most times it is the heater.

Answer 4

Rangefinder has the right idea.  The drain from the freezer to the pan under the refrigerator is plugged up - most likely with ice.  You can see this drain line behind the refrigerator.  When the freezer goes through an automatic defrost this drain line is used to get the water out of the freezer.  Try a thorough manual defrost to see if the line opens up - you will have quite a bit of water in the tray underneath and it might overflow.  That is probably all you will have to do to fix this problem.

Answer 5

It probably is a leaky door gasket on the bottom.Just replace it.

Answer 6

Sometimes it's the simple things that go unnoticed. There's a high probability that someone else's answer is right, however, another possibility is that somethings wrong with the flapper on your ice dispenser (assuming you have one) and the outside air is getting in at the dispenser and causing the problem. Open the door, look through the dispenser- if you see light, there's your problem.

Answer 7

place a dollar bill between the door and the freezer area,close the door and pull the bill out,if it comes out real easy you have a leaky gasket around the door area and should be changed.

Answer 8

The Freezer and frig are probably listed as frost free. If so you have a frozen drain or clogged drain port there somewhere in the bottom of the freezer. You also have mullion heaters to melt of ice and a defrost timer that melts the frost out at a regular rate. Three things to look for:  clogged drain, bad defrost timer, bad mullion heater strip.
