(2) installation method of dual temperature dual control thermostat, install the thermostat to temperature In the control box, insert each color line in the original position, and then proceed in four steps:
①Plug the two main connecting rods into the temperature control adjustment button, and fix the display cooler thermostat box;
②Pry open the two instructions Light assembly box: When you pull out the indicator assembly box to separate the secondary connecting rod from the main connecting rod;
③Pull out the indicator assembly box properly to separate the secondary connecting rod from the main connecting rod, and Unplug the two secondary connecting rods in turn and install them to the main connecting rod;
④ Install the secondary connecting rod and the indicator light assembly box to the display cooler body, and try to adjust the two thermostat adjustment knobs. , Weak block and have a certain resistance, then insert the temperature sensor tube of the thermostat into the display cooler and fix it in the original position, seal the temperature sensor tube of the thermostat with sealing glue, and restore the condenser to its original position.
(3) Diagnosis of dual-temperature dual-control thermostat The diagnosis method of refrigeration thermostat is basically the same as that of ordinary thermostat, that is, it should be turned on at normal temperature and turned off at low temperature. At normal temperature, the inlet end of the refrigerating thermostat should be connected to the C end (connected to the compressor) and disconnected from the S end (connected to the solenoid valve); at low temperatures, it is the opposite of normal temperature. When the refrigerating thermostat is open, the display cooler usually shows that the freezer compartment is normally cooled but the refrigerating compartment is not cooling; usually the refrigerating compartment freezes and the freezing effect of the freezer compartment is poor.
(4) Damaged treatment of dual-temperature dual-control thermostat. Damaged dual-temperature dual-control thermostat can only be replaced with a new one, and a special dual-temperature dual-control thermostat must be used, because its parameters and the length of the temperature sensing tube are the same as those of ordinary temperature. The controller is different. When the display cooler appears band. When the display cooler has a refrigeration non-stop failure, the time controller cannot be used like a normal display cooler.
3. Disassembly and diagnosis of the indirect display cooler thermostat. The indirect display cooler thermostat is set in the refrigerating component box. Pry open the fixing screw cover of the module box, unscrew the fixing screw, pull out the module box and expose the thermostat, you can disassemble and assemble.
