Ice Buildup
Under certain conditions of temperature and humidity, ice can form on the dehumidifier cooling coils. The ice buildup can impede airflow and eventually form a solid block of ice encasing the cooling coils. This buildup prevents the dehumidifier from operating effectively, and can cause water damage if condensed water drips off the accumulated ice and not into the collection tray. In extreme cases, the ice can deform or distort mechanical elements, causing permanent damage.
Many better quality dehumidifiers have a so-called frost or ice sensor. which simply turns off the machine, allowing the icy coils to warm and defrost, before automatically restarting. Most ice sensors are simple thermal switches, and do not directly sense the presence or absence of ice buildup. An alternative design senses the impeded airflow, and shuts off the cooling coils in a similar manner.

Famous quotes containing the words ice and/or buildup:
“Like the water, the Walden ice, seen near at hand, has a green tint, but at a distance is beautifully blue, and you can easily tell it from the white ice of the river, or the merely greenish ice of some ponds, a quarter of a mile off.”
—Henry David Thoreau (1817–1862)
“I think those Southern writers [William Faulkner, Carson McCullers] have analyzed very carefully the buildup in the South of a special consciousness brought about by the self- condemnation resulting from slavery, the humiliation following the War Between the States and the hope, sometimes expressed timidly, for redemption.”
—Jimmy Carter (James Earl Carter, Jr.)
