Common problems and solutions for ice makers? (1)

1. Symptom: The compressor works but does not make ice
Reason: The refrigerant leaks or the solenoid valve is damaged and not closed tightly.
Maintenance: After leak detection, repair the leak and add refrigerant or replace the solenoid valve.

2. Symptoms: The compressor keeps working to be able to refrigerate, and the water pump keeps working to pump water. The ice cubes continue to thicken, but the ice cannot be dropped during the dehydration process.
Reason: The failure of the water temperature probe makes the intelligent control system unable to effectively sense the water temperature and work, misjudging the program error, or the controller failure.
Maintenance: Use a multimeter to measure the resistance of the water temperature probe (when the water temperature in the water tank is close to 0℃, unplug the three-core wire in the control box and test the resistance of the two wires on both sides), if the resistance is lower than 27K Above, it is judged that the controller is bad and should be replaced. If the resistance is lower than 27K, you need to disconnect any of the two wires, and adjust the resistance to 27K to 28K by connecting the resistance in series. between.
3. Symptoms: The machine enters the de-icing program (the water pump stops working and the compressor stops cooling) but the ice does not fall off.
Reason: The defrost solenoid valve is damaged.
Repair: Replace the solenoid valve or outer coil.
4. Symptoms: The water shortage light is on but the machine does not automatically enter water.
Reason: There is no water in the pipeline, or the water inlet solenoid valve is faulty and the valve does not open.
Maintenance: Check the water inlet of the pipeline, and restart the machine after opening the waterway if there is no water. If the water inlet solenoid valve is faulty, replace it.
5. Symptoms: The compressor is working but the water pump has not been working (no running water).
Reason: The water pump is damaged or the internal scale of the water pump is blocked.
Maintenance: Clean the water pump or replace the water pump.
