Three initial possibilities to try first. Check the temperature of the freezer compartment. The ideal temperature for this area should be from 0 to +10 degrees. Most newer freezers have a humidity control dial to keep it from sweating. Turn the dial to lower the humidity level. Also when you removed the icemaker to defrost it, you should have dried it out thoroughly (in the sun or by the furnace register for an hour or two) to eliminate any condensation which could have frozen up some very important components. If all of these are functioning properly then write back.
