Freezer (top unit) iced up and the bottom (refrigerator) got warm---56 degrees F. I melted the ice from the freezer but the bottom still doesn't get cold, although the freezer gets quite cold (0 degrees F). The temperature control for the freezer is set on Normal (3) and for the refrigerator on 1 (max cool). There seems to be a little fan at the top of the duct going from the freezer down to the refrigerator. The ice invaded the vents at the top of the duct and may have stalled the fan, causing it to fail.

The self defrost mechanism is not working. The evaporator is getting blocked with ice, an insulator, and that affects freezer as well as refrig temps. When you unplug unit the ice melts and it will work till the ice block returns.
Check that the fan motor wiring has not been disturbed. If the freezer fan is not working, the fridge will generally start cooling but due to poor air circulation , it will stay colder at the back but will get warmer at the front hence causing the ice to melt. The usual temp for a food compartment is around 4 degrees. The freezer should be -18 degrees celcius.
Sounds like the defrost circuit of your fridge has failed. If you remove the back panel of the freezer compartment, you will see the evap coil encased with ice. Normally the defrost circuit will turn off the compressor and turn on a heater to warm the coil to about 45 degrees to melt any frost build up. After about 40 minutes the compressor will kick back in to keep your fridge cool again.
The typical failures are that the defrost heater burns out. If you have an older fridge, the defrost timer fails to advance, causing the fridge to stay in cooling or defrost mode.
if the fridge part is cool and freezer is fine what problem are you having?is the fridge not cold enough? a common problem with bottom mount freezers is the freezer door doesn't get closed all the way,warm air enters the freezer mixes with the zero degree air and freezes up the air ducts,when you open the freezer door you should hear the fan blowing,if it is check the ceiling in the freezer to see if ice is on it,check the packages for frozen water droplets and stick your hand in the fridge where the air ducts are to see if you can feel cold air blowing into the fridge,if you can't feel air blowing into the fridge,unplug it,open the freezer door,remove the top basket and remove all the food out of the bottom basket,with a hair dryer blow into the back wall into the vent holes and melt out all the ice in the ducts,you'll see water dripping down through the vent holes,when the water stops dripping plug it back in and see if the fan is blowing the air into the fridge.also you can remove the bottom kickplate and you should see a tech sheet in it,read it and it will tell you how to put the machine into defrost,it will stay in defrost for like 20 minutes,you can do this instead of unplugging it, there's a heater that comes on behind the back panel in the freezer,this can help you melt out the ice but if it seems to hard to do just unplug it.
Hi, If your ice maker has stopped making ice then you need to check these things. The lever that controls the ice maker has been pushed
up which turns it off. If you have a red lever, pull it down to the
wire and if you just have a wire then just pull down the wire to start
your ice maker up. Make sure the freezer temperature is below 10 degrees
F If the freezer is too warm ice production will be poor because the
ice maker will not cycle properly. The ice maker fill tube may have ice formed in it,
blocking it. Use a hair dryer to melt the ice. Watch out for the
plastic parts, so that you do not melt the plastic. Also check the
water inlet valve and the shut off valve, to make sure it is not
plugged with debris. The openings in those valves are very small. Check the gears in the ice makers to see if they are
broken or stripped. Also look to see if the ice rake is broken. All
parts in the ice maker are replaceable individually, If you find broken
parts replace them.
check if the fan is working and you are circulating air efficiently. You may check on the coils at the freezer if there are ice formation. I would suggest to have the ice melted by unplugging it and ensuring that all parts are ice free. Clean the unit while at it.
Get yourself a thermeter and see what the tempeature is in the freezer. It should be "0" degrees or colder. If it is hanging around 30 degrees +/- you may have a compressor or control problem. You may have a drain tube clogged that takes the water out of the freezer. I am not familar with your model but many freezers are similar.
1) Bad defrost thermostat 2) Bad defrost heater 3) Bad defrost timer 4) Failed evaporator fan motor.
Look for frost accumulated inside the louvers at the back panel, top and bottom. If you see it, remove food from freezer and put in ice chest. Take out shelves, get hair dryer and warm the backside of the freezer, directing air down the louvers. Then leave to sit for 4-6 hours with the freezer door open. Put towels in the bottom of the freezer to catch any melted ice. After period of time, plug unit back in and power the unit back up. Once you know it's cooling, empty ice chests back into freezer.
If there is a problem in any of the above components, then it will show up in 3-4 weeks witht he same problem again.
