Kelvinator 0USH71
DEFROST HEATER OVERLOAD
SKU: KEL0USH71
Condition: NEW
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.
A heating element converts electrical energy into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. This process is independent of the direction of current.
All restaurant equipment has protection from short circuits or power overloads that could damage the internal power supply or cause a fire. Fuses and circuit breakers are two commonly used mechanisms for overload protection. Overload protection can be automatically enabled in response to high pressure or high temperature situations. Circuit breakers may be manually activated to interrupt the flow of electricity for the purpose of planned equipment maintenance or serviceable repair.
