indirect cooling display cooler maintenance experience
display cooler Common failures involving devices Except for the following two types of failures, the failure rates of other devices involved in other failures are the same as those of ordinary display coolers. The compressor does not start to run and there is no power response, and the rotating defrost timer still does not work. Most of the problems are overload protectors and thermostats, followed by damage to the defrost timer and compressor. After two or three days of refrigeration, there is no refrigeration, and the defrosting circuit has a problem. One time the machine fails, most of the defrost heaters, defrost thermostats, and defrost superheat insurance are open, and a few are damaged by the defrost timer. The secondary failure machines are mostly caused by the wrong model of the defrost timer, the incorrect installation position of the defrost thermostat and the superheat fuse, followed by the defrost heating wire, defrost thermostat, defrost superheat fuse, and The frost timer is damaged.
Inter-cooled display cooler Common troubleshooting procedures Door lights do not turn on. Inspection procedures, fans do not run, inspection procedures, poor insulation, inspection procedures, no defrosting inspection procedures such as three, dual temperature dual control display cooler maintenance experience dual temperature dual control display The cooler electrical system adds a refrigeration thermostat and a two-way electromagnetic reversing valve on the basis of the ordinary display cooler, and the operation of the reversing valve is controlled by the refrigeration thermostat. The refrigeration system adds a freezing capillary tube and a two-way electromagnetic reversing valve to the common display cooler. Except for the following two types of failures, the devices and probabilities involved in other failures are the same as those of ordinary display coolers. Good freezing and refrigeration, but not refrigerating, but can start and stop: involves two components of electromagnetic reversing valve and refrigeration thermostat, of which refrigeration thermostat accounts for 90%, and electromagnetic change valve accounts for 10%. Refrigeration also freezes but can be turned on and off: it involves refrigeration thermostats and two-way electromagnetic reversing valves, and the two-way electromagnetic reversing valve is damaged, and it is mostly damaged by electrical components. Dual-temperature dual-control display cooler The identification method of the two capillary tubes: install the electrical parts of the solenoid valve, weld the solenoid valve inlet, and switch on the display cooler power to ensure that the solenoid valve is vented first when the refrigerating thermostat works in the cooling state The outlet is the capillary interface of the refrigerator compartment, and the other is the capillary interface of the freezer compartment.
