Something here should cover your problem.

Try rearranging all items inside fridge and freezer so that air may circulate around all items easily and then check seals on doors and ensure doors are closed completely and not leaking cold air. Also do a complete thaw/ defrost. You can remove the plastic coverings and ensure all ice is defrosted. Using a hair dryer will speed up thawing/defrosting process.

sounds like 2 things either the t stat making fridge run all the time, or 2 the fan not having enough cfm to circulate the air.

most of these freezers have an automatic defrost cycle.
after so many hours of chilling it will stop and run a de-icing cycle.
this is accomplished by one or two heating elements.
if one of the elements is burned out it will not run the defrost cycle.
and will ice up quickly.
depending on the model the heaters will usually cost about 15 to 20 dollars and they are easy to replace.
look up the model of your freezer and download the pdf files they will usually have a pictorial diagram showing the location
a defrost timer usually does nt fail on them unless it is physically damaged.

Either, the defrost timmer has had it, or the freezer defrost element has failed, the element is the most common cause of this type of problem. You have ice build-up in the freezer cores because it cant defrost, all frostfree units rely on cold air from the freezer to blow into the fridge, if the freezer cores become blocked, air can not pass to the fridge side. I bet you, if you left the unit off for 2 days to defrost totally,,,,with the doors open...then plugged it back in, it would work like new for 2 weeks.
Timmer or defrost element needs to be replaced...do not fall for the trick that the fridge mech. has to take it away, you tell him that this is the problem and you will save yourself ALOT of cash.

Dont forget to vote for the solution...regards Russ

try to clean the drain of your unit maybe it is clog up declog it to avoid drip. u said that ther is a build up of ice this means auto defrost not activate try to chek the defrost heater or defrost timer if have the unit this. or try to allign the door gasket possible theres a gap entry of outside air cause of build up of ice. bec it is came from moisture of air out side or avoid to much door opening.goodluck.

check the timer maybe your Fridge it has timer to defrost or is set to auto defrost try to make set to manually defrost..or if you have manual of that item read it for guidance..

Most probably defrost thermostat is defective. Unit never goes into defrost, ice forms on coil and in floor of freezer. After defrosting may work OK for a week or two but gradually gets warmer because ice is blocking ports where cool air gets to refrig. May also have water in refrig box. Can also be caused by defective defrost timer. This can also be caused by the drain hole being blocked by ice. You MUST remove all ice in drain under freezer coil. Use turkey baster to squirt hot water into hole and use hairdryer to defrost.

Make it a habit to defrost it every week. You see, when ice forms around the evaporator tubes (which runs around the walls of fridge and freezer), heat exchange reduces (that means heat is no longer absorbed from the things inside the refrigerator) and cooling stops. See whether freezer walls or fridge walls are damaged. Do not use knives or any other sharp tools to remove ice. Do not forcefully remove items that are difficult to take out from the freezer. Defrost and remove them.

You have a defrost problem. It means you have 3 parts that can be involve ( timer, defrost thermostat, element) most of the time it's the timer. Hope it was helpful. :)
