The freezer coil in the lower freezer section freezes up with ice. I have the upper section at 5C and the freezer 18C. We first notice that there is water under the fruit drawers and the fridge seems to be running a lot. This tells me that it is time to take the inside of the freezer apart and apply heat to the coil until it is free of ice. The coil is so full of ice that the freezer has to be heated to remove the outer panels as the ice is holding the panels.

the drip ledge is for the drain hole in the middle which should be cleaned periodically.it is fitted for the condensation from the fridge to drain away.the "droplets"are ice crystals and one droplet is normal running,two us for fast freeze(when you have just filled/started from warm)the lights are "on and running"......fast freeze.......and overheat warning.as far as level 3 is concerned,get a frezzer thermometer and run the freezer at -18C and the fridge at +3C to 5C.,as it will change depending on the weather/kitchen temperature.(summer and winter).

freezer minus 18C
fridge plus 2 to 5C
use a proper temp guage as units are just guides.

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.


Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer. If this repeatedly happens with yours, you may can prevent it by taking a bare copper wire and wrap it around a fin near the heater and put the other end a few inches down the drain. The heat convection may prevent it from freezing.

also perhaps the defrost timer is bad, not allowing the defrost heater to come on and melt the ice as it should? Or the defrost heater itself could be bad -

YOU HAVE A DEFROST PROBLEM. FROST HAS BUILT UP SOMEWHERE AND THE FAN CAN'T BLOW PAST THE BLOCKAGE. OR ONLY A SMALL SECTION OF YOUR COILS IN THE FREEZER ARE COOLING DUE TO A CLOGGED FILTER OR BAD COMPRESSOR. PULL THE BACK COVER FROM INSIDE THE FREEZER AND LOOK AT THE COILS. THEY SHOULD HAVE A LIGHT FROST AVER THE ENTIRE COIL.IF IT IS A BIG BLOCK OF ICE YOU HAVE A DEFROST PROBLEM.

If you only had ice buildup in one section of the evaporator you have a weak/inefficient compressor.
You need a new compressor or a new refrigerator.

If the coils are also icing up you have an auto defrost problem.

Either the evap fan has a problem, or the defrost system has failed. You should never see frost in the freezer section as the defrost sensor should sense that the coils need to be defrosted before that much frost accumulates.

Unplugging to clean out helped because the frost got a chance to melt away.

If you find the evap motor is running, then the things to check are the defrost sensor, the defrost timer, and the defrost heater.

Weird scenario... the first thing I would do it to remove the interior back panel of the lower freezer section after the unit has been running for hours and check the coils to see the frost pattern on them. Should be even white frost all over the coils with no solid frozen coil (block-O-ice thing). Check the fan is running above the coils, etc. when. If everything is OK then you may have a control board problem. Let us know what you find in the freezer coil investigation and we can go from there.
