What Are Some of The Reasons Why A Block Ice Machine Doesn't Make Ice?

Ice block machines have been widely used in the field of refrigeration, preservation, and cooling in China, and the production technology of ice block machines has also reached a very mature standard. However, there are some common minor problems with this kind of mechanical equipment.

Common causes of ice-making failure in block ice maker machines include:

1. No Response When Starting the Unit

If the block ice maker unit fails to respond upon startup, it's often indicative of a refrigeration unit malfunction. To troubleshoot, first verify the presence of power in the main supply and measure the voltage. Also, inspect the electrical control box of the block ice machine to ensure its normal operation.

2. Normal Refrigeration but No Ice Production

When the ice block making machine is functioning well in terms of refrigeration yet fails to produce ice, the root cause may lie in the water distribution tray. There could either be a water shortage or an excessive amount of water. You can adjust the water supply valve on the ice bucket's water supply pipe. Refer to the instruction manual to set the water level of the water distributor to an appropriate position.

3. Compressor and Motors Inoperable with Full - Protection Indicator On

When you press the start button to initiate ice generation, and the compressor and other motors do not work while the ice-making full protection indicator light is illuminated, multiple issues could be involved. It could be due to a powered-off main switch, a damaged start button, or a malfunctioning PLC computer board.

To diagnose, check if the ice storage is actually full. Examine the anti-icing switch for fullness to see if it's damaged. Also, verify the power supply, check the main power brake for damage, and assess the PLC computer board for malfunctions.

4. Compressor Runs but doesn’t make ice

If the compressor of the block ice machine operates normally, but no ice formation, the typical reasons are insufficient refrigerant in the block ice machine or a damaged two-way solenoid valve. A faulty solenoid valve can cause the compressor to fail to seal tightly.

You can check the refrigerant level. If it's insufficient, add an appropriate amount of refrigerant. In case of a damaged solenoid valve, replace it with a new one.
