    Really sounds like your defrost cycle isn't working. Open your freezer compartment and take the back panel off to inspect the coils. Might have to manually defrost it. And if your unit is new might have to get a new control board. If you are lucky it has a defrost timer and that is a lot cheaper to replace. Also check out your freezer fan make sure it is working.

Your defrost system must be on the blink. The defrost system is used to keep slabs of ice from forming and disrupting flow of air to that fresh food compartment. In the old days grandma would just unplug the unit every 2 weeks and place a chair in front of the the ice box, holding the door open for an afternoon to kill the frost buildup. Then came the modern frost free icebox. Every 8 hours the timer would kill the compressor and kick in a heater to melt that old frost. A bi-metal thermostat was installed in line with the heater to shut it down at 50 degreesF, then the ice box would just keep quite and set a spell (21 mins) then like magic the ice box would roar back to life, get cold, and chill out. That is until you opened the ice box door and violated grannys 3 second rule and caused the compressor to come roaring on and scare the cat half to death. Nowadays instead of timers(we don't need no stinking $2 timers) we built in computer boards with fancy sensors to monitor capacitance changes in the evaporator coils and issue orders from main computer board to defrost board to commence defrost cycle all the time monitoring for any changes in our daily habits, taking in consideration of how many times we peek into the ice box and look at grandmas strawberry shortcake. Keeping up with each and every ice cube we consume and checking the temperature and quality of our water and ice in the door. OH my! So what could go wrong? Well barring hurricanes, tornatoes, thunderstorms, earthquakes, and other natural disasters, all ice boxs still need a heater and a thermostat. I would start there. Of course if you had have specified a particular model number and brand so that a date age and a few components could have been looked at then I could have posibly given a more specific answer.

Hotpoint Future fridge freezer - freezer working well but top of the back of the fridge has a large build up of ice ??? And doesn't appear to be keeping the food cold enough


here are lots of things that can cause cooling problems. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure. In such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. The fridge compartment's temperature rise is usually (but not always) the first to be noticed. Frost" and "Ice"
There is a difference between "frost" (a white, snow-like substance) and "ice" (usually clear and solid). When referring to what is seen during an inspection, please keep this distinction in mind as the possible causes for each are often very different. The Defrost System
Inspecting the (usually rear) wall of the freezer compartment for a frost build up is necessary. (In the case of many GE top freezer models, check the freezer's bottom panel.) If there is a frost coating on it, it is often a sign of excessive frosting beneath it. Sometimes however the evaporator cover panel will actually need to be removed (see the illustration below) before an excessive frost build will visible.
The refrigeration system's evaporator (cooling) coil is usually in the freezer compartment. This evaporator will periodically frost over and have to be defrosted by means of a heating system. When the defrost heating system fails, the frost can accumulate to such a degree that airflow throughout the appliance is hampered. There may be just enough air circulation to cool the freezer section but that will eventually stop too.

Why do I have ice build up in my freezer


Ice build on the freezer box floor or White frost build up on the freezer box back wall (inside). Ice layer on floor means your drain line blocked. White frost layer means your machine is not going into defrost cycle.

Excess water dripping into refrigerator from freezer. I am in the process of defrosting. Ice build up behind freezer back wall. Do I need a new heater or will clearing the ice from drains suffice?


Hello,

Clearing the ice build up is a good start,the problem though is the drain pan under the coil in the freezer thats iced up is blocked so when the defrost heater comes on and melts the frost from that coil,it the water is collecting in the freezer and in many cases drips into the fresh food compartment,clearing the drain will resolve your leaking/ice build up issue.THE DEFROST HEATER IS GOOD melting the frost in the first place and hence forth that melted frost stays in the freezer and becomec ice.

Refrigerator is barley cold, still makes ice, condensation inside of frostless freezer


Hi: The fact that it still makes ice tells me the freezer is a zero degrees. When you said condensation in the freezer did you mean frost? If your defrost heater fails it will cause the frost free freezer to build up frost. The frost will build up and block the vent that supplies the cold air to the fresh food. The defrost heater is behind the metal wall at the back of the freezer, at the very bottom. A glass tube with a metal coil in it. The coil can break and stop the defrosting. Replace that. Use a hair dryer to melt the frost from behind the panel. All of it top to bottom. You need to remove all the frost to free up the airways. I hope this helps, Jeff

If the ice build up is only on the back panel of the freezer then you have a defrost problem. Most likely a defrost thermostat or control board/timer. If frost build up is around the walls of the freezer then warm air is getting into the freezer. Most likely cause of this would be gaps in or torn door gasket or door alignment. In some cases the door was left cracked open. If gasket and door alignment is ok remove the frost and see if it comes back.
