普通双门双温电冰箱温控器的特性及故障判断与修理（Characteristics and fault diagnosis and repair of thermostat of common double door and double temperature refrigerator） Characteristics and faults of thermostat of common double door and double temperature refrigerator Judgement and repair Characteristics and faults of thermostat of common double door and double temperature refrigerator Judge and repair (Haier refrigerator) Ordinary refrigerators use mechanical pressure thermostat as temperature control device, once the temperature Controller malfunction, refrigerator can not work properly. The temperature controller has many kinds and different models, Different specifications of the thermostat, structure, performance and use are not the same. Also, when the refrigerator When the stop and stop is abnormal, not all the temperature controllers fail, and must be made for the fault characteristics Correct judgement and avoid judgment. When you receive a refrigerator that doesnt work properly, first of all, be sure Determine whether the refrigerator is in good condition. According to the opening and closing time and the system can be achieved The cold effect can be judged, and the method of prolonging the startup time can also be used by observing the refrigeration To determine the speed and depth of cooling. In short, the premise of completely eliminating the failure of the refrigeration system must be Next, the fault of the temperature controller can be determined. The key to the application of this theory in practice is: No. Fewer maintenance personnel on the refrigeration status is not accurate, it is clear that the refrigeration system failure, but easily It is decided that the temperature controller is out of order and that the temperature controller is adjusted or replaced blindly, which adds trouble to the maintenance work. If the refrigeration system has been completely normal, it is a temperature controller fault, and the same model or model can be replaced The thermostat is different,
