Frost over the box tells me that you do have refrigerant flowing through the evaporator coil. If the coil has a defrost element as you stated it should also have a fan for circulating the cold air. Apparently your fan is not operating.

We have Frigidaire Upright Freezer. After 6-7 days its stops cooling as its condenser gets ice around it whereas the fan is working good. We clean the ice and it again starts working/cooling.


There are a few possibilities. Freeze-ups are a result of the unit either not having sufficient airflow or the compressor running too long and too often. As you note the fan is good, chances are airflow is not the issue. There are a few quick items that you can check on:

1. Check door seals. Leaks will cause the interior to lose cooling faster and result in compressor overloading.
2. Do not overload the freezer. Too much inside the freezer will cause loss of airflow INSIDE the unit and can cause issues.
3. Avoid putting too much unfrozen material into the freezer at once. It takes a lot of work to remove all the heat from a large amount of material.
4. Avoid multiple opening and closing of the door. Upright freezers are inefficient as they lose all their cold air as soon as you open the door. Chest freezers do better if you must go into the unit often.

Lastly, undercharged refrigerant system can cause the same issue. If you don't have any of the other problems noted, have a serviceman check the refrigerant and fill the system as needed.

GE bottom freezer stopped cooling


The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions.

Freezer side not freezing


Check for ice / frosting inside the freezer .... If present you probably have a defrost problem.... This causes the freezer coil to ice up and block the air flow ... the causes could be a bad defrost heater , defrost timer, defrost sensors, or control board. Also make sure that the condenser coil is clean. remove ALL dust with a vacuum and a coil brush .the coil is located either on the bottom or on the back side of the unit... You didn't give the Make and model #

Does it make sense that a frigidaire plhs67egsb3 refrigerator freezer could stop working simply from overloading? The compressor is running, the condenser coil was clean but the evaporator coil was frozen...


the defrost heater or thermostat circuitry is bad,you need to test both components,also the defrost timer control if the other parts test o.k..,the defrost tstat has to be below 32 degrees or it will test bad/open,when the evaporator coil gets iced up you cannot blow cold air through a solid block of ice,(NO air flow)means no cold air throughout the unit even with the evaporator fan running

FREEZER MAKING ICE, BUT FOOD IS THAWING


If you have a Freezer on the top model Kenmore, with warm temps in the fridge, AND water dripping onto the top shelf of the lower fresh food compartment (FFC), this is usually caused by a clogged defrost drain. Since Kenmore is not an actual manufacturer of anything, they take other brands, i.e. Kitchenaid, GE, Frigidaire, etc., take their names off and put on a shiny Kenmore nametag. This is a common problem with Kitchenaid refrigerators. You can determine if your Kenmore is made by kitchenaid by looking at the model # tag. the first three digits will indicate the manufacturer, Kitchenaids begin with the sequence, 106.*.If this is indeed how your model # begins, keep reading. Since the water cant go down the drain tubing to the pan at the bottom of the unit, it builds up on the freezer floor, eventually blocking the air return vents from the fridge to the freezer, and the vent from the freezer to the fridge. YOu can check this very easily. Look at the ceiling of your FFC, near the back. toward the sides you will see two square holes, about 2" square, stick your finger and feel around the inside of those holes, do you feel any ice/frost, or do you just feel styrofoam, you might even see frost/ice below the level of your ceiling? This drain usually gets clogged with defrost water that does not completely drain, then of course it freezes, eventually plugging up the drian hole located at the level of your freezer floor, behind the back wall. The water keeps accumulating, and freezing, on the freezer floor, eventually filling in and clogging the air vents..no air flow , the fridge wont cool. The easiest way to resolve this, empty out all contents and store someplace cold for 24 hours...a 2nd fridge, outside in a cooler if its cold like here in chicago. After its empty, unplug, open both doors and blow a fan for 24 hours. Prepare for an abundance of water due to melting ice.
After you defrost, you can plug it back in and it will be fine, HOWEVER, I suggest you take the back freezer wall off, you might have to take a floor cover off first, likely 2-4 screws in both the floor and the back wall. When you have the evaporator exposed, you will see a black cal rod defrost heater underneath the evaporator, as well as your drain hole just to the right of center underneath both heater and evaporator. Take a piece of 12-14 gauge solid, not stranded wire, removing the insulation and exposing the entire 6-8" piece of copper wire. wrap the wire around the diameter of the cal rod heater, 3-4 turns should be sufficient, and stick the other end of the wire down that drain hole. This will melt any ice that will build up in the future, everytime your unit goes into defrost cycle, so this wont happen again.

If air vents are clear of frost/ice, next thing to check is the back wall of your freezer, does there appear to be frost/ice/snow on the back wall? If so, your unit is not defrosting. On most Kenmores, this is usually caused by your defrost timer, located in the canopy mounted at the top of the FFC on Top freezer models, or your defrost thermostat, which is clipped onto the evaporator coil inside your freezer. Again, if its a 106 model Kenmore, this thermostat will have a pink and a brown wire coming into/out of it. My suggestion, if it isnt defrosting, change both. tjhe defrost control will connect with a plug, but you will have to hard wire the thermostat, ( cut wires from old, strip wire, and connect using wire nuts and electrical tape.)

Since y ou mentioned the water accumulation, more water recently, my diagnosis would be the former versus the latter, as the lack of actual defrosting coincides with lack of defrost water, however I'll never say never.

If your unit is a side by side model, check for ice on freezer floor...clogged drain. Check again for frost/ice on back wall, not defrosting, check same two parts, (the heaters rarely go bad on Kitchenaids, but never say never) You should also check for air flow into fridge, even if no frost / ice visible on back wall. Open the FFC door, and locate the air vent near the top, back of the fridge, on the left wall. While depressing the door switch, AND WITH THE FREEZER door closed, put your finger/hand near that vent. Do you feel any cold air? If you dont, you could have a bad door damper, not uncommon, or a bad damper control--> the temperature control WITHOUT the off or "0" position.

If any of this seems a bit overwhelming, I suggest you have a reputable repair technician check your fridge.

Oh, and lastly, you WILL NOT have two compressors, one for each compartment, nor will you have two sets of defrost heating elements, one for each half.
ALL cooling for 99% of refrigerators made in last 25 years takes place in the freezer, with the fridge being an empty box, except for an air intake vent, and an air exhaust vent which leads directly back into the freezer. When a refrigerator unit seems to still be cold in the freezer, but not cold enough or not cold at all in the FFC, its ALWAYS going to be caused by lack of air flow. But as you can see, there are a few things that can cause that lack of air flow.

Freezer is getting to about o degrees but refrigerator section wont go below 50 this is amana side by side asb2623hrw also changed the defrost timer about a month ago and blew off the coils from underneath...


Check your lower air shutter that lets cold air move from the freezer to the refrigerator's. You may have something blocking the air flow, food, plastic, etc... There should be a dial that opens, and closes the door.

Freezer doesnt freeze and red light at top came on


If freezer is icing up, you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow.
You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model

Side by side refrigerator is not cold. Bottom freezer is.


if the freezer is cold and the fridge is not then it can be several things. The freezer could have a bunrt out defrost heater, defrost timer faulty, fan not working in the freezer??. all of these things will stop your fridge getting cold, but your freezer will still be around minus 9 deg c. you wont get any air into the fridge as the coil in the freezer is prob all iced over. Dont worry about the heat on the door frame as it is only the anti sweat heater
