Symptoms 1: compressor work but no ice making

Reason: the  leakage of the refrigerant or the damage of  solenoid valve .

Maintenance: add refrigerant after leak detection or replace the solenoid valve

Symptoms 2: The compressor can do the refrigeration , water pump still keep working, the ice is getting thicker, but can not get into the process of dehydration off the ice.

Reason: It is the fault of water temperature sensor disable the intelligent control system to do the effective temperature perception misjudgment program error, or controller is disabled.

Maintenance: use a multimeter to measure the water temperature sensor resistance (inside the water tank water temperature at the time of close to 0 ℃ degrees, remove the control box of the three core line, the two wires on both sides of the test of resistance), such as resistance less than 27 k, the judgment for the controller is bad, should be replaced, such as resistance less than 27 k, need to disconnect one of two thread root, through the way of series resistance of resistance is adjusted to 27 to 28 k k.
