Their are a few things that couldbe causing your refrig.troubles.
1) their is ice build up in the return air vents that is not allowing air to flow correctly you can see the air vents under the crispers in the ref.floor and can see if they blocked with ice.
2) the freezer fan is bad and not circulating cold air into and out of the ref.
3) In addation to the defrost timer,perhaps the deforst heater and defrost thermostat are bad and frost is building up in the freezer,Do ya see frost build up in the freezer??
1. Defrost the freezer if you see ice on the inside wall. This is a very common problem. Before you call a technician do this. Defrost the freezer completely, and when you put the items back, make sure that the vent are not being blocked. The fan needs to circulate the air inside the freezer to keep it from having frost. Ice build up causes circulation problem which causes the ref and even the freezer to not get cold enough. Since the thermostat senses that it is not getting cold enough the refrigerator runs constantly and producing even more frost. Then the owner turns the refrigerator to coldest setting which actually do not help, or maybe make the problem even worse, all the while running up the electric bill as well. So there you go.
The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. 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.Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:Poor cooling 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.The defrost timerThe defrost thermostat (also called the bi-metal switch)
One of the most common problems with freezers is their tendency to build up a thick level of frost and ice that can disrupt performance. The ice can form on the hoses and cause the fan to freeze up. While you want the freezer to be cold, too much ice is not good for the freezer or the food inside it. There are multiple reasons a freezer could start to develop frost buildup.
Freezer Overstocked Frost can build up in the freezer if there are too many items inside of it. Air cannot properly circulate around the freezer, so the areas with the sitting cold air can freeze the moisture. Frost continues to build up and accumulate, which then allows it to spread. If food is stocked up near the fan, cold air can't get past it, and the fan itself could develop frost to the point where it freezes and stops working entirely. This can be prevented by not overstocking the freezer and by evenly distributing food throughout.
Temperature Setting Too Low The freezer should have a thermostat that regulates how cold it gets. If the temperature is set at too low of a setting, the freezer kicks into high gear, the air freezes outright and frost quickly builds up. Adjusting the thermostat to a higher temperature or level can counteract this problem, but you may need to de-thaw the freezer to eliminate the frost that has already built up inside.
Keeping the Fridge Door Open Many people keep their fridge door open for extended periods of time while they examine the contents inside to see what they want to eat. This can contribute to frost buildup in the freezer, because the fridge is taking in a lot of warm air during this process and the fan pushes it up into the freezer. The moisture in that air is then quickly frozen, and ice can build up substantially as a result. The longer the fridge door is held open, the more likely this can occur, so the best solution is to only keep the fridge open for short intervals and then to not open the door again for a while.
Hope this tips will help you. : )
I had this repaired by replacing the motor-fan in the refrigertor behind the air deflector which sends the air from the freezer to frig. hope this helps. The motor was not working.
ice build up means your refrigerator is not going through defrost cycle. you have ice build up on evaporator which restricts your cold air flow into the fresh food side. check defrost timer, defrost thermostat located on evaporator behind the wall where your getting frost. check defrost heater. it wraps under the evap.
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.
One of two things. When you open the freezer drawer, do you hear a fan running? If not, that's the problem. The Evaporator fan. Its' job is to circulate cold air throughout the entire cabinet. Without it, things get toasty.
If not the Evap Fan, it'll be the sealed system... meaning that it's developed a leak and freon is escaping (not harmful for you or your Family). If it's just under 5 years old, this will be a warranty repair. Over 5? Bad news... it'll cost ALOT to have it repaired.
