ServiceManual_2018-V1.0 10. Circuit description 10.1 Power Supply AC input power is reduced into 12V by means of TOP chip switch on/off and T1 transformer, then output stable DC12V by LC filtering, ,DC12V is for provide power to relay(control strong electricity),lamp, electric valve and so on, the relay controls on-off of the compressor, defrost heater, and some strong electric components.
ServiceManual_2018-V1.0 10.2 Door trip test circuit As for using the normally-closed door switch, when the door is closed, the chip detects the voltage of 5V, and determines that the door is in the closed state; when the door is open, the chip detects the voltage of 0V, and determines the door is in the open state.
ServiceManual_2018-V1.0 10.3 Temperature test circuit The characteristic that resistance value reduces as the temperature increases is deemed to have negative slope or negative temperature coefficient (NTC), and such thermostat is called as NTC thermostat. The resistance value changes sensitively with temperature and typically changes 7% ~ 3% per degree centigrade. Sensor used in the refrigerator is NTC thermostat.
