Defrost Cutout Thermostat & Thermal Fuse with Harness has unique technology having dual contact devices patented automatically reset at a preset temperature. An electrically isolated bimetal disc is used to either open or close the circuit current.
Description:
1. Easy to install in small or narrow spaces due to slim shape.
2. 3 wire leads, fuse, -14-celsius degree normally open.
3. Defrosted thermostats are a kind of thermal protector used in Air-cooling frostless refrigerators, also use as auto temperature limited switch and Heating compensated switch in the process of heating and defrosting in refrigerators.
4. Automatic temperature control for removing frost and for protecting the frozen rupture in the cold storage.

How often should a refrigerator defrost?
To maintain the efficiency of a manual-defrost freezer, it should be defrosted each time it develops a quarter-inch of ice build-up on the interior walls. Many people defrost their freezers once a year, but you may find that you need to do yours more or less often depending on your usage habits.
