Why is the refrigerator difficult to start
Summary: When present this kind of situation, should check the power voltage at first, if the voltage is too low, the coil electric current started on the cutting out device is too little, the contact can't be sucked and shut, make the compressor unable to start; Voltage can damage compressor while being too high.
In peak period using the refrigerator in summer, but many friends reflect to me, say the refrigerator of the family can not be often started, the refrigeration result of the refrigerator becomes worse, but does not know what reason the refrigerator happens on earth oneself. Today, the editor brings the reason of difficult start of He Bing's case for everybody.
When present this kind of situation, should check the power voltage at first, if the voltage is too low, the coil electric current started on the cutting out device is too low, the contact can't be sucked and shut, make the compressor unable to start; Voltage can damage compressor while being too high.
The voltage of normal use of the refrigerator is 187 --During 242 volts. Secondly every sport one in the compressor is because of lacking the oil, will emit louder sound when the compressor is started, and difficult to start. Because compressor duration is relatively long, will make some lubricating oil enter the other positions, lubricating oil insufficient in the compressor, make between the various sport work, happen, be, rub. At this moment, can annotate 30 to the compressor --50 ml of lubricating oil.
In addition, the compressor is inactive and keeps improperly, make the internal part get rusty because of being made moist for a long time, difficult to present to start the phenomenon. Moreover, the compressor inhales and arranges the angry valve stretch breaking, chip block the interval between the sport one, make the compressor swipe each other between the spare parts while starting, not merely increase the resistance while starting, and will emit the abnormal sound. Finally, the metal powder or pipeline within the system enters systematic solder particle while welding, flow and enter the compressor with refrigerant, when the compressor operate, will scratch the inner part and emit the unusual sound, make the compressor difficult to start. At this moment, should cut the outer cover of compressor and repair or change the compressor.
Except that the above several are plain, for instance, the compressor is started again in less than 3 minutes after shutting down, the high, low pressure has not reached the equilibrium yet to increase the compressor systematically at this moment. This situation appears, should try hard to open the door few after paying attention to shutting down, shorten the time of opening the door, should not put too much food to refrigerate, let alone put the articles of higher temperature, in order to guarantee the temperature in the case adds the time of the temperature of rising to the compressor and starting the machine and is greater than by 3 minutes, do not influence the start next time.
The family is everybody's dream, everybody's family has different styles, have a sincere one, there is a magnificent one, there is a brief one, no matter what kind of family it is, people pay attention to enjoying that relaxation that life bring at home even more now, unrestrained!Enjoy at home, please enter while sampling life:Channel of the houseThe editor recommends:There are many questions on active service of over years of water heaters
