Ice build up in freezer and temp in fridge section not very cold

Yes it has a fan you should here it and feel it. It sounds like your defrost coil may have gone out. Take the back pannel of the freezer off and see if it is clogged with frost.

FREEZER /FRIDGE NOT COOLING:Optimumrefrigerator temperature at or below40° F(4° C). The freezer temperature should be0° F(-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these

Checkurcold control thermostat,urthermistorsin both fridge and freezer ( they should be checked for both ohms and for amount of current being put out as perurmodel ),urair flow vent from freezer to fridge.( to make sure it opens and closes without any restrictions) Onthermistorscheck for A close circuit and amount of ohms not just an Ohm reading. As perurmodel. Most shouldatleastshow 1200 ohms. Also Check door seals for leakage.
Evaporator coils
Poorcooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.
If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.

FAN check to see if it is operating or restricted A fan that is not blowing or restricted will not circulate the cold air properly.

Often, the first thing that folks do when their refrigerator starts to feel warm is turn both controls on the coldest settings.This is exactly the WRONG thing to do.Turning the cold control to the coldest settingwillkeep the compressor running longer and make lots of cold air.But turning the air door to the coldest settingclosesthe airway to the food section. Lots of cold air is made, but most of it stays in the freezer section, and the food section actually getswarmer.

Frost can build up for multiple reasons. Most common is the start os an iceblock. Other reasons can include condensation from door being left open or opening too much. It can also happen from backsplash from the inlet tube for the ice maker. If the fridge is running non stop. It sounds like the ice block is forming and the temps are not getting to the program temps. If at factory setting the freezer should be at or around 0 degrees and fridge should be between 42 and 48 degrees. Has the fridge shutdown at all to go into defrost? The defrost timer may have went out and is causing an iceblock. If there is an ice block always change bimetal/ defrost thermostat.

Hi,

Sounds like the defrost timer/board may be hanging up....

if one of the panels in the fridge has frost on it, the evaporator coils may be iced up. this restricts the cold air flow. to defrost: empty the fridge and freezer, turn it off, remove the panel in the freezer that has the frost, use a hairdryer and defrost the ice buildup, sop up excess water, dry it up, replace the panel, turn it on (while it's empty), set the temp halfway, and close the doors. when the compressor turns off, fill the fridge. if the panels are frostless and the coils are warm, you may be out of refrigerant from a freon leak somewhere. it might be cheaper to replace the fridge.

due to lots of moisture in the air or high humidity it creates extra frost in the freezing unit this creates blockage in the air flow once the ice crystals build up. the freezer is what keeps the fridge at the normal temperature if the air flow between the two are blocked in the ducting then the fridge temperature will rise the best way to solve this is to open the freezer take out the 4 screws in the back panel tilt the panel forward and blow it with a blow dryer till the ice chunk has melted its a good idea to use a towel and on the top self of the fridge to obsorb excess water this can be kinda messy. or you can unplug your fridge for about 6 or so hours. good luck hope i helped. :)

too much ice bulid up will stop enough cold air being blown into the fridge.Try turning it off letting all ice melt then turn it back on again and set thermostat at a lower temp.There may be ice you can't see.

Your frost free is not defrosting properly. There should be no ice buildup in the freezer section. Frost in the freezer section stops air circulation to the refrigerator section.

From your comment. It's not that you have to defrost the parts, that's what they're called. "defrost timer", "defrost t-stat" and "heat element". Defrosting the whole fridge for a few days actually will clear the ice blockage if that's it but it will return in a couple weeks if the "defrost cycle" isn't doing its thing. A fridge typically goes into some form of "defrost cycle" to keep it "frost free". As an example, every 12 hours the compressor turns off and the evap. fan turns off then a heat element turns on to melt the light coating of ice on the "cooling coils". Once about 1/2 hour goes by the heating turns off and the cooling turns back on again. This repeats over and over to keep the ice from building up too much. If that cycle is broken, the ice will build and build till the whole coil is a block of ice. Then the air can't flow around it to provide cold air for the whole unit. It acts basically like putting a large block of ice in the freezer and keeping the doors closed... without a fan to move the cold air only the very lower portion of the freezer is cold, the rest is warm.
