If the ice machine fails, it is actually not as difficult as you think. Some glitches just require you to use your hands. The most important thing is to understand the cause of the failure so that we can prescribe the right medicine to solve the problem. The editor below will introduce to you several common faults of ice machines. Friends who are interested should take a look!
1. Ice machine failure phenomenon: compressor works but does not cool.
Cause of failure: Refrigerant leakage or two-way solenoid valve is damaged and is not closed tightly.
Maintenance method: After detecting the leak, repair the leak and add refrigerant fluid or replace the solenoid valve
2. Ice machine failure phenomenon: the compressor keeps working to cool, the water pump also keeps working to pump water, the ice keeps getting thicker, but it cannot automatically enter the de-icing process. The program freezes.
Failure reason: The water temperature measuring probe is faulty, which prevents the intelligent control system from effectively sensing the water temperature and working, misjudgment program error, or controller failure.
machine maintenance method: Use multimeter to measure the resistance of the water temperature probe (when the water temperature in the water tank is close to 0°C, unplug the three-core wire in the control box and test the resistance of the two wires on both sides), such as If the resistance value is above 27k, it is judged that the controller is bad and should be replaced. If the resistance value is lower than 27k, any one of the two wires must be disconnected and the resistance value must be adjusted to 27k to 27k by connecting resistors in series. Between 28k.
3. The ice machine enters the de-icing process (the water pump stops working and the compressor stops cooling) but the ice cubes do not fall off.
Cause of failure: The two-way solenoid valve is damaged.
Repair method: Replace the solenoid valve body or outer coil.
4. The ice machine water shortage light is on but the machine does not automatically replenish water.
Reason for the failure: There is no water in the pipeline or the water inlet solenoid valve is faulty and the valve does not open.
Ice machine maintenance method: Check the water inlet in the pipe. If there is no water, open the waterway and restart it. If the water inlet solenoid valve is faulty, replace it.
5. The ice machine compressor is working but the water pump has not been working (no water flowing)
Cause of failure: The water pump is damaged or the water pump is blocked by scale.
Ice machine repair method: clean the water pump or replace it.
6, ice machine compressor water line condenser and some refrigeration equipment are all normal, but why does it not freeze?
The reason why
does not freeze should be that Freon is not enough, or the fluorine pipe filter is clogged, or there is too much Freon and it will not make ice.
The above are common problems that occur with ice machines, and the editor also gives solutions. You can practice it according to the editor's method
