4. eral minutes 2 The quantity of system the extra gas will occupy some and then open charging tube Gas is too much space of evaporator so that the area of heat discharge all of gas Change a exchange becomes less unit will work not new filter and then recharge gas 1 Leakage of Gas well finally sealed the system Phenomenon of failure a higher pressure of liquid cycle system than norm b higher temperature of condenser c larger electric current of compressor d there maybe ice on the suction tube e when gas is too much some gas liquid might goes back into compressor compressor will be damaged by liquid The air in system will cause lower efficiency of cooling Phenomenon of failure 3 There is air in the a higher pressure of liquid cycle system liquid cycle system than norm but the pressure is not over the limit b higher temperature of discharging tube C much noise General when a compressor works for many years some parts of compressor were wear so that compressor discharge less gas out unit does not work strongly Phenomenon of failure 4 Low working a lower pressure of discharging check the efficiency of pressure of system with pressure meter to Change a new compressor compressor see if it is normal b higher temperature of compressor surface C cut off the discharging tube to see if you can block the gas coming out of the tube when compressor is working Some time there is something blocked the f
5. guid flow disappears The pressure of absorbing becomes negative The phenomenon above will appear again and again The way to check ice blocking Warm the capillary with a hot towel after a while the ice in the capillary melt you can hear a sound of gas flow comes from the capillary abruptly The pressure of absorbing becomes higher It is Ice blocking B there is offal block the capillary Phenomenon of failure If the capillary is blocked by something such as offal etc the sound of liquid flow disappears The ice on the evaporator defrosts First stop unit for several minutes and then The pressure of absorbing open charging tube discharge all of gas becomes negative Blow the cycle system with gas of nitrogen Higher temperature of discharging Change a new capillary and filter and then tube recharge Gas finally sealed the system The way to check offal blocking If you warm capillary with the way of checking ice blocking there is no change It must be offal blocking COMPRESSOR NEVER STOPS 4 Too much food in the refrigerator 5 Wind door is broken Replace wind door 6 Fan motor is broken Replace fan motor Note e Before doing these operations above disconnect the main power supply Failure to do so could result in electrical shock or personal injury e Incase of any detailed technical information please check with the technical specifications
6. he motor operation sound in the compressor is appears to be louder at night or begin starting which is a normal phenomenon also the uneven placing would lead to too much running noise 6 1 Is the food with special smell sealed tight 6 2 Does it have long time storing food or degenerated food 6 3 Whether the internal cabinet needs cleaning the forefront or the 7 1 As fridge Anti condensation tube is placed here and caused the above middle cabinet heats phenomenon which is normal Refrigerator s two sides or the back heat the cabinet surface 9 1 Air humidity is too large condensation The solution for the ccmmon problem Ice up in the freezing chamber There is a peculiar smell in the units 8 1 As condensation tube is placed here and caused the above phenomenon which is normal 1 Cooling is not enough good Many reasons might cause that cooling not enough good as blow If some gas leaked unit will work not well First find out the point of leaking Phenomenon of failure on tube and then sealed it a lower pressure of liquid cycle system vacuuming it finally recharge with b high temperature of copper tube of Gas discharging gas hand feels very hot Note C much noise sounds like ZZZZZ comes If you find oil on somewhere it is from outlet of capillary possible that leakage point is d the temperature fell down very slowly there If too much Gas was charged into the cycle First stop unit for sev
7. ilter of liquid cycle system so that unit is not cold Phenomenon of failure a lower pressure of discharging b lower temperature of discharging First stop unit for several minutes and then open charging tube discharge all of gas Change a new filter and then recharge gas finally sealed the system 5 There is something that blocked the liquid cycle system Change a new filter 2 NO COOL Popular failure reasons are below Phenomenon of failure First find out the point of EXHI on tube a leaking fast and then sealed it vacuuming it finally b leaking slowly recharge with gas C no voice of liquid flowing Note d cut off charging tube no gas If you find oil on somewhere it is possible goes out that leakage point is there 2 There is some thing A Ice blocking First stop unit for several minutes and then 1 Leakage of gas that blocked the liguid Sometime because unknown open charging tube discharge all of gas cycle system reason water comes into liguid Blow the cycle system with gas of nitrogen cycle system the capillary will be and then recharge Gas finally sealed the blocked by water after unit runs for system period of time Phenomenon of failure The unit works well in the inception after period of time the ice appears in the capillary and becomes more and more till blocks the hole of capillary completely In the moment you can find the ice on the evaporator defrosts The noise of li
