When the refrigerator is low in the winter indoor temperature (generally less than 12 degrees), the speed of the temperature rise in the refrigerator will become very slow, causing a thermostat (mechanical temperature induction contact switch, by induction refrigerator)The temperature of the temperature and low temperature control compressor cannot be closed in time, the compressor cannot start working properly, affecting the refrigerator refrigeration, so the manufacturer adds a small power electric heater in the refrigerator
refrigerator, passedSwitch control, in winter, the switch is turned on, and the electric

heater will work with power, so that the temperature in the refrigerator is raised, and the contacts in the thermostat will close, so that the compressor starts to ensure good cooling effect..And other seasons (typically at room temperature than 12 degrees), the compressor can automatically start, and do not need the electric heater to work, at which time the temperature compensation switch is closed to avoid increasing power consumption.
