Is the trap door flap closing properly where the ice comes through the door? If open, warm air would be coming in frosting and maybe iceing things up

SOURCE: Fridge won't get cold

Check to make sure that the fan in the freezer is running whenever the compressor turns on to cool the unit down. If the fan's not going, warmer moist air from the fridge will make the air duct frost up. The fan needs to be running to blow the cold air into the fridge section.

SOURCE: Frost and Ice Buildup

If everything is cooling fine and the frost is not on the back wall but just the floor at the bottom then your defrost drain is stopped up. Remove the bottom basket and clean up the ice on the floor of the freezer. Look on the back wall and you will see some more ice up a littler higher at the back. This is where the drain is. Clean all the ice out from this area too using hot water or a hair dryer. Once you find the drain hole make sure you get all this ice out of it as well. You can take a screw driver once you have melted the ice and gently push it through the drain hole. Once the hole is cleared you should be able to pour hot water freely through the hole. (It is best to turn the refrigerator off while you do this)

SOURCE: freezer is cold, but fridge isn't cooling,

Hello,

All of the cooling in refrigerators is normally done in the freezer compartment. A fan circulates cold air from the freezer into the refrigerator compartment to cool it. Most likely this fan has quit working.
Also note that,

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. mostly, 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 the 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.Hope this helpout , Good luck

We have an amana fridge that has stopped cooling. I've called 2 repair companies, in the meantime I cleaned everything I can clean. And other ideas? Fridge is about 12 years old


The part that needs cleaning is the condenser fins by the compressor. If those are clear, then it probably needs a top up of refrigerant gas. It may also be ice on the evaporator which is inside the fridge where the cold air blows from.

Early harvest no ice or thin ice


There is an adjustable potentiometer in the pcb section. Adjust it to give a thicker cube. Also check water pump and clean any scale buildup from the sprayplate. If all else ok and still no ice suspect evaporator sensor.

Cold on the top part but not cold on the bottom


Check the fins in the back of the "bottom" part for frost / ice buildup. It may be time to defrost your fridge.

Alternatively, if there is a lot of food crammed onto the top 2 shelves, it can prevent the air from circulating around the fins. Also check your door gaskets, especially if you have of frost / ice building up on the fins.

Hello i have an lg refrigerator GR-620RW which


LG 620 RW water in fridge below crisper problem.
The issue is most likely a blocked condensate drain line at the back of the freezer. The purpose of the drain line is to take away the water from the end of the defrost cycle.
Task time, approx 2 hours.
Unplug fridge.
Empty out the fridge, let warm up & remove the back panel of the freezer. There is a 3" x 4" snap in door at the upper left corner of the back panel with a round snap in cover. Remove the snap in cover & remove the screw to take out the 3" X 4" panel, gently pull out the back panel from left to right. There is also an elect connector to the fan on the upper right corner, unclip this. The drain is at the back in the centre, it will likley be blocked with 2 or 3" of ice. You can let it melt or sparingly use a hair dryer on it, do not over heat or damage the coil/fin assembly. The fridge will continue to drip water for a day after the drain is cleared if the water has rin inside of it for any period of time.
There is also a fan/control assembly in the refrigerator section held up by 2 screws & snaps. This should be dropped down to ensure there is not ice buildup in the vents to the freezer or water inside it.
Finally, make sure you run warm water down the freezer drain tube to the pan underneath the fridge, this is accessible by taking of the rear compresser cover behine the frigde. Ensure the lower drain line is clear & back on the locater peg.
Of course if you want to do this the easy, & have the time, leave the fridge open, unplugged for 2-3 days & the ice will all melt.

Good Luck

Fridge not cold - freezer fine


ice buildup will most likely block the air flow.
if so the air will not be able to enter fridge section. Check air vent in fridge side if you can hear the fan and get no air flow then its blocked - common defrost thermostat failure.

to temporarily clear the problem just use a hair dryer on the ice build up area
