Our dehumidifier has formed a sheet of ice amongst the coils and will no longer pull moisture from the air. The hole from which the water drips is completely iced over. It is 70degrees in the room and...
Turn the unit OFF and unplug it from the wall. Allow it to thoroughly thaw and remove the humidifiers cabinet to expose the cooling coils. Clean those thoroughly and coat with a very light coating of WD40. Reassemble the humidifier and turn it ON. Set your humidity control at 50% and allow the unit to run for at least one hour. Check for water collection in the bucket and for any signs of icing, after one hour. If water is in the collection bucket and no signs of icing, lower the humidity to 45% and continue. If you not any signs of icing, watch the unit, as you need to know if it automatically goes into defrost mode. The compressor should shut off, but the fan will continue to run until defrosting is completed. If it doesn't the auto defrost sensor has failed and will need to be replaced.
Hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks.
