Just bought a year, has been open, and the day before yesterday suddenly did not refrigerate, and inside things are melting, and this morning to see, the inside thing began to have a little freezing, and this is how the matter? This has never happened before.
Your refrigerator is not refrigeration, should be judged from the following aspects:1: check the power supply connection is normal.Open the door, observe the lamp is lit, or with a pencil test.2: if the power supply is normal, listen to the compressor is working.The compressor will operate with a slight vibration and vibration (such as using the hand to feel the vibration of the compressor), it should be careful not to burn, because the compressor temperature is 40-50 degrees Celsius in winter, summer can reach 80-90 degrees Celsius3: if the compressor can work, to determine whether the refrigerant system refrigerant (commonly known as liquid).
(two) elimination method1, cut the casing, replace the buffer pipe, or tighten the screws.2, first find out the system leakage parts, welding, test pressure, time after the qualified, add refrigerant to a certain amount, usually by evaporator filled with frost or refrigerator within the rated temperature shall prevail.3, capillary or dryer plug, export heat, and for this reason, to be removed and removed! In addition, household refrigerators generally have direct cooling and indirect cooling two, direct cooling by means of evaporator (cooling) and direct freezing, refrigerating chamber for heat exchange and cooling purposes; indirect cooling refers to the evaporator (cooling pipe) and refrigeration chamber separated by a fan of the air blowing in the freezing and refrigerating chamber and cooling purposes.
2, the leakage of refrigeration system, refrigerant compressor running all gone, though, but no refrigerant evaporation system, so the refrigerator temperature does not drop.3, capillary blocked, refrigerant can not enter the evaporator, heat absorption, the refrigerator temperature does not drop.
(1) cause analysis1 、 compressor high pressure output buffer tube broken or fixed the pipe screw loose, resulting in high-pressure pipe does not exhaust, low-pressure tube does not inhale, so the compressor is running, but not refrigeration.
