Norlake 146428
TEMPERATURE/DEFROST SENSOR KIT
SKU: NOR146428
Condition: NEW
The defrost sensor, also called a defrost bi-metal thermostat, shuts off the defrost heater if the heater gets hot enough to damage the evaporator. If the defrost sensor fails, the heating element doesn't turn on, and frost builds up on the evaporator resulting in warm temperatures in the 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. The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer: For every 6, 8, 10, 12 or 24 hours of compressor operation it turns on a defrost heater for 15 minutes to half an hour.
A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive heating of the freezer compartment. The defrost timer is such that either the compressor or the defrost heater is on, but not both at the same time.
Sensors are used in restaurant equipment to perform a variety of functions, such as monitoring and controlling temperature, humidity, pressure, and other operating conditions such as voltage, amperage, viscosity, flow, motion, light, the level of liquids or product, vibration, force, speed, proximity and more.
