DEHUMIDIFER COILS FREEZE OVER, WHETHER MACHINE IS RUNNIG ON LOW OR HIGH. FILTERS ARE ALL CLEAN.
Turn the Master ON/OFF Switch to OFF, unplug the unit and allow it to thaw out completely. You may want to put some old towels under it, to absorb the dripping water. Once it has completely thawed, remove the bucket, the air intake filter and the face of the cabinet. You should now have access to the coils. Clean them with a mild soap and warm water. Rinse and thoroughly dry the coils. Once they are totally dry, spray a very light film of WD40 on the coils and then wipe off any over spray. Reinstall all the remove parts and test the unit.
Keep in mind, if you are using the dehumidifier in a basement, the air temperature at floor level is colder than at chest level. Dehumidifiers don't work well between 40 & 60 degrees F. (Unless, they are a low temp unit). Any lower, the coils will freeze. Raise the unit up off the floor onto a sturdy table or counter top, that can hold the weight of the unit plus, a full tank of water. In a basement application, doing usually solves the problem of freezing coils.
If after doing all the above, the coils still freeze during operation, the compressor may below on freon and needs to be recharged. Or the defrost sensor on the unit, needs to be replaced.
Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.
