Refrigerator power supply normal, built-in lighting, open door light, can hear the sound of liquid flow on the back! The compressor works with a slight vibrating sound! No refrigerationThe cooling switch is adjusted for 5 gears
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.
(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!
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.
