I have a freezer/refrigerator combo, with the freezer on top. Ice is building up on the bottom of the freezer. What is cause this? How do I get it to stop?
place a dollar bill between the door and the freezer area,close the door and verbs the bill out,if it comes out real easy you hold a leaky gasket around the door area and should be changed. Defrost heater have failed.
Defrost timer has bungled
Defrost thermostat(terminator) has failed.
One of these 3. Most times it is the oven.
Sometimes it's the simple things that dance 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 rime dispenser (assuming you have one) and the outside air is getting surrounded by at the dispenser and causing the problem. Open the door, look through the dispenser- if you see light, there's your problem. The Freezer and frig are probably down as frost free. If so you have a frozen drain or clogged drain port there somewhere contained by the bottom of the freezer. You also have mullion heaters to melt of rime and a defrost timer that melts the frost out at a regular rate. Three things to look for: clogged drain, bad defrost timer, bleak mullion heater strip.
Poor trademark around the door.


You could have a problem with the thermostat anyone turned too low or not working. Otherwise a fridge does build up if it doesn't have a admirer fitted like in the frost free fridges. It probably is a leaky door gasket on the bottom.Just replace it.
Answers:    Rangefinder has the right concept. The drain from the freezer to the pan under the refrigerator is plugged up - most predictable with ice. You can see this drain smudge behind the refrigerator. When the freezer goes through an automatic defrost this drain file is used to get the water out of the freezer. Try a thorough instruction manual defrost to see if the line opens up - you will hold quite a bit of water within the tray underneath and it might overflow. That is probably all you will have to do to fix this problem.
