Cooling diagram Checking the Thermostat Use a multi-meter to test the resistance between L & C when the thermostat is at normal position... - Page 7 such as: “ 1, 2, .. 7” : If there shows “000”then the thermostat is OK If there shows anything but “000”then the thermostat is always at OFF Position and compressor will not start ever. Use a multi-meter to test the resistance between L & H and C&H when the thermostat is at shut position such a s “0”: If there shows no response then the thermostat is OK If there shows anything (have response) then the thermostat is always at ON Position and the...

Page 8: Checking The Compressor
Checking the Compressor Use a multi-meter to test the resistance between C & S, M&S and M&C : Normal range of C&M : About 10-30Ω Normal range of C&S : About 10-32Ω Normal range of S&M : About 20-60Ω If the test result is not in this range then it means the inner coil has some problem and the compressor can not work properly. -
Page 9: Checking The Heater
If there show 000 or no response then it is broken. Checking the Heater If defrost system failure，check the heater and the temperature fuse as well as wires. Measuring temperature fuse and heater resistance about 361Ω then it is OK.( Blue and Yellow) Checking the timer Timer is an importance control component for air defrost refrigerator’s defrost system. - Page 10 1 means power port 2 means defrost port 3 m eans c ommon por t 4 m eans c ompressor po rt 1、1-3 is the timer coil running connect wire port. 2、3-4 is compressor running connect wire port 3、3-2 is defrost heater working connect wire port Checking method as following picture: As picture, set the timer to the compressor running, use the multimeter measure the foots of 3 and 4, if the value of resistance is 0000, it means normal.

Page 11: Checking The Defrost Fuse
As picture 1, adjusting knob as the picture it mean into the defrost, other area is compressor working. As picture 2, adjusting the timer to defrost working, then use the multimeter measure the foots of 3 and 2, if the value of resistance is 0000, it means normal. Checking the defrost fuse Fuse is a high temperature protector of defrost system, when defrosting, if it feel the temperature is more than 73℃, it will cut off the defrost heater, stopping defrost, so that it can protect the parts. -
Page 12: The Instruction Of Replacing The Thermostat
Picture 1 Picture 2 The picture 1 is defrost thermostat As picture 2, using the multimeter measure two foots of defrost temperature sensor, it should be open circuited. If you want to judge the defrost temperature sensor is good or bad, you can put the defrost temperature sensor into a refrigerator’s freezer (The temperature is below -18℃... -

Troubleshooting ◆The common problem judgement method Problem Cause 1.1 Is the power cord connecting well？ 1.2 Is the power voltage too low？ 1.3 Is the sensor irrational setting? 1.4 Is the ambient temperature too low? Refrigerator can’t start 1.5 Is the circuit on power? 1.6 Is there some default in compressor 1.7 Is the refrigeration system blocked by ice or dirty, please stop the unit and restart after 10 minutes to see if the compressor can start. -

contracting or expanding, this sound will be made, which is normal. 5.8 The 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. - Page 22 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 Change a new compressor.

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.
