Defrosting a freezer with an improvised water collection method. In refrigerators, defrosting (or thawing) is the removal of frost and ice.. A defrosting procedure is generally performed periodically on refrigerators and freezers to maintain their operating efficiency.
A defrost timer taken out of a household refrigerator. The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. [1] The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer.
Most refrigerator-freezers—except for manual defrost models or cheaper units—use what appears to be two thermostats. Only the refrigerator compartment is properly temperature controlled. When the refrigerator gets too warm, the thermostat starts the cooling process and a fan circulates the air around the freezer.

The electric heat in defrost mode is needed to keep the system from blowing cold air inside the building. The elements are then used in the "reheat" function. Although the thermostat may indicate the system is in defrost and electric heat is activated, the defrost function is not controlled by the thermostat.
Adsorption refrigeration was invented by Michael Faraday in 1821, even though the basis of artificial modern refrigeration dates back to 1748 with William Cullen's experiments. [1]
Sabbath mode, also known as Shabbos mode (Ashkenazi pronunciation) or Shabbat mode, is a feature in many modern home appliances, including ovens, [1] dishwashers, [2] and refrigerators, [3] which is intended to allow the appliances to be used (subject to various constraints) by Shabbat-observant Jews on the Shabbat and Jewish holidays.
