Frost occuring inside the frig on the top around mechanism

Have you ever heard of this? All temperature controls are set to normal and freezer and frig are both working and cooling fine. Why is there frost inside the frig? It is only on some sort of mechanism on the roof of the frig near the back. Greatly appreciate any help! Just want to know if this is a fixable problem or it's time to say goodbye to the frig.
Thanks!

J,
Frost is indicative of an air leak (which means that the door seal is messed up).

Pardon me while I jump off into a thermodynamic primer here...

All of the "cold" is made in the freezer compartment. There's a fan in there that circulates this chilled air around... Only a portion of the chilled air is directed (ducted) to the fridge (beer) section.

Here's where the nifty thermodynamic whiz-bangs happen... Hot air balloons float why? Because they're lighter than the air surrounding it! (And a hot air balloon is "attracted" [like a magnet] to the coldest spot in the atmosphere) Ya know why? Because nature abhors a vacuum. Nature is always in a struggle to balance itself. So the cold air above actually pulls the balloon into the air and tries to stabilize its' temperature and equalize it with the surrounding environment (at that equalization moment, you wouldn't wanna be in the basket... know what I mean? Crash, Boom, Bang)

By "refrigerating", we are, by nature's rules, "breaking the law". We're actually pulling (removing) heat (calories) out of the food and transferring that heat to the outside of the fridge. Nifty, huh? Instead of applying "cold", we actually are removing heat!

Ok, OK... back to your issue. Frost is only water vapor that is suspended in air... When this warm air comes in contact with a "cold" surface it condenses OUT of the warm air and clings to the colder surface... think of a glass of iced tea on the patio, you know how the glass "sweats"? Imagine that your glass of tea is 22 degrees below zero Fahrenheit and now imagine what would happen to all the warm moisture laden air surrounding it. Yep, you're right... It would sweat out on the coldest surface and then quickly freeze/frost.

Now back to the balloon thing... (and nature). .. Cold air is "heavier" (more dense) than hot air, right? So if there's a leak (think of air as a fluid) of cold air [which flows toward the floor] there MUST be a replacement, right? (The whole "nature abhoring a vacuum" thing) Cold air flows out and warm (moisture laden) air fills the vacuum. Where does this warm air go?

Yep! It goes where the balloon goes! To the coldest spot it can find! (You're good at this!) Where's the coldest spot in the fridge, you ask? Well? It's at the top left, inside the cabinet. In the very back, you'll see the damper. It's used to adjust the amount of cold air flowing into the fridge compartment. When warm air hits this (the coldest part of the fridge) it immediately condenses and frosts over. This frost builds up a wall. This wall stops air from circulating. When air stops getting to the fridge, your eggs spoil, your mayonaisse stinks and your beer isn't worth squat.

Now for the "WHY" of it all... Could be several things allowing warm air into the fridge.

First thing to check is the rubber door gasket. Make sure it's seating properly all the way around the door. If it's not, the door may be warped... try to warp it back into shape. You have to do this physically.

Second, use some "Vaseline" and rub a thin layer of it onto the door gasket (the part that seals against the frame). Not only will this help make a good air-tight seal, it'll also help keep the door gasket supple and intact for the life of the refrigerator.

Take this knowledge and prosper... (only AFTER you've rated this soltion as "FixYa", though)

Hello,
A refrigerator not cold enough is a hassle, because you are at risk of spoiling the foods you store in there. Most often, this problem is caused by something easy to fix. 1. Faulty Door Gaskets
The door gaskets in a refrigerator ensure a sealed closure every time you shut the door. Torn or loose gaskets on the door of the refrigerator can result in a leak in the cold air. As a result, the refrigerator is warmer. Repetitive and frequent opening and closing of the refrigerator is also a possible cause, because the warm air from outside replaces the cold air in the refrigerator every time you open it. 2. Dirty Condenser Coils
Dirty condenser coils can result in improper functioning of the refrigerator. These coils are located on the back or the underside of refrigerators. If you find this to be the cause of the problem, unplug the refrigerator before you attempt any cleaning. 3. Frost-free Feature not Working
If the frost-free feature fails, it causes a buildup of frost around the evaporator coils in the freezer. This causes a malfunctioning of the evaporator fan that blows cold air around. The fan can also be damaged if it hits the frost. 4. Faulty or Incorrect Temperature Control
A faulty thermostat can lead to a refrigerator that is not maintaining the desired coldness. Check for this problem and also ensure that the temperature is set to the correct level. Normally, refrigerators are set to a temperature of about 0°C, whereas the freezer sections are around -17°C. 5. Inadequate Air Flow inside Refrigerator
A refrigerator that is loaded with too many food items can fail to maintain an adequate level of coolness across all the items kept in it. The surface items tend to be colder, and the items underneath do not become as cold. A refrigerator that has very few items in it can also fail to function efficiently. Try to ensure that your refrigerator has enough food in it at all times, but is not so loaded that the air flow gets constricted. 6. Vents between Freezer and Refrigerator Clogged
The vents between the freezer and refrigerating section blow cold air from the freezer across to the refrigerator. If these vents are clogged with ice, the air is blocked and the refrigerator does not cool down. If this is the case, you can unplug the refrigerator, wait for the ice to melt and then connect it back to the power supply. 7. Faulty Door Switch
The door switch is found on the bottom of refrigerator doors. It turns off the light in the refrigerator and resumes cooling action when you close the door. If this switch is not functioning properly, the refrigerator will not be cold and it will also be affected by the heat of the interior light. 8. Refrigerant Leak
A refrigerant leak is very unlikely. This problem can cause malfunctioning of your refrigerator. If you suspect this to be the cause, contact a service technician.
Hope this will help out....

Hi,

All the cooling coils for this model are in the freezer section. There is a fan down there behind the back wall on the top. This fan directs air up to the fresh food section.

Check the temperature of the freezer you can do this by inspecting the ice cream, if the ice cream is soft you are above 5 degrees F. If you have a good cold freezer then the problem is with air flow, the evaporator fan that I spoke of could be bad).

If your freezer temperature is not as cold as it should be you may have a defrost problem, look for any signs of frost build up on the back wall of the freezer section, if you see frost you will most likely need to put in a new control.

If the freezer temperature is warmer than normal and you do not have frost you may have a sealed system leak, this will require a technician for sure.

Refrig compartment does not cool on my new Kemore Frig.


Check and make sure the fan in the freezer is running. if not possible bad fan. If fan is running, check to see if you have any ice built up on back freezer wall. Normally frost type ice. If so, you may possibly have a bad defrost bi-metal mounted in the freezer section. Next could be a defrost timer control. Model number usally will help more in getting it right.

Bottom frig is not cold enough. just connected after 1 yr


Ok do this. Boil some water in a pot then use that to defrost the freezer. This is caused by ice build up in the vent that is keeping the cold air from coming into the refrigerator. Make sure it is defrost completel though cause the ice that is built up is mostly inside and can't be seen. That will solve ur problem I guarantee. Then set the temperature to normal. Like half way. This keeps the frost from building up. Believe it or not as refrigerators get a bit older they actually get even colder and therefore frost build up is more likely. Since no refrigeration can be made completely leak proof, small amount of the freon has leaked out older fridge, and this actually cause it to get colder. You don't need a service technician just defrost then set to a lower setting thats it.

Fridge works freezer isnt getting cold enough to freeze


check to see if you have frost on the back panel of the freezer if so then defrost the unit and if your able to find the failure of the defrst heater or defrst thermostat,or the defrost thmer more than likely its the mother board since its a general electric frig but if you manually defrost until a repair tect can come then it will run normal until it frost up again but before you call the tech out make sure you have the frost on the back panel otherwise he'll make several trip trying to solve the problem with the frig unless its the defrst heater

Hotpoint frig,top freezer motor runs contiunally, thermostat set in middle of temp. control. side of frig stays cool all time.[does not get warm as it used to] is defrost thermostat bad or timer?


niether. is there frost on back wall of freezer? if no look behind back wall and see if there is frost on all the coils when running. if less than 80% is frosty...freon. or is there frost covering back panel..if so then defrost problem would be correct. but side would be warm so I think not.

Frig section not cooling and at time appears to stop but freezer is ok


There is one compressor, condenser and evaporator in all refrigerators. The part that makes the cold inside the unit is the evaporator. It's in the freezer, behind a barrier on the back wall. It's a "coil" with many small fins. There is a fan that blows air over the evaporator which makes the air cold. This air comes from the freezer and stays in the freezer. The cold food section (the refrigerator) has a control that opens a hole for air to pass from the freezer to the fridge. This being said...you can rule out the "temperature control" for the fridge.

The sound you hear could be the compressor relay, the evaporator fan or maybe something else. It could be bad, it could be not too bad. (Like a fan blade a bit unbalanced with dust)

OK,,, back to the evaporator. There is a little heater next to the coil that turns on every 8 hours or so to defrost the coil. That's called the "defrost cycle". Makes sense, no? If the defrost timer (common problem) or defrost control board (common problem) go bad, your evaporator coil freezes up, and that's not good for anything in your refrigerator. But it can often keep the freezer section cold. You can easily disassemble the evaporator cover in the back of the freezer and take a look. If it looks like a block of ice, you probably have a defrost issue. An even, thin coat of frost is OK, but lots of ice is a no no.
