How to Check for Malfunctions in a Desktop Ice Cream Cabinet?

As a crucial device for the sale and storage of cold drinks, any malfunction in a desktop ice cream cabinet can not only affect the quality of ice cream but also cause economic losses. Therefore, it is essential to master some basic methods for checking malfunctions. Next, we will introduce in detail the inspection steps and solutions for common types of malfunctions.

 I. No Cooling or Poor Cooling Performance

When it is found that the desktop ice cream cabinet has no cooling effect or the cooling performance is not ideal, first check the power connection. Confirm whether the power cord is properly plugged in and whether the socket has power. This can be judged by checking whether the power indicator light of the ice cream cabinet is on or by using other electrical devices to test the socket. If the power supply is normal, then check the setting of the thermostat to ensure that the temperature adjustment knob is in the appropriate gear. Sometimes, incorrect operation may lead to an overly high temperature setting.

After ruling out problems with the power supply and thermostat, the compressor needs to be checked. A normally operating compressor should have a slight vibration and running sound. If the compressor does not start, it may be due to a compressor malfunction or a damaged starter. You can touch the outer shell of the compressor with your hand. If the shell is hot and there is no running sound, it is likely that the compressor has malfunctioned. If the compressor can start but stops after running for a while, it may be that the overload protector has activated. It is necessary to check whether the overload protector is damaged or whether there is a short - circuit problem in the compressor. In addition, if the condenser is too dusty, it will affect heat dissipation and lead to poor cooling performance. Regularly clean the dust and debris on the condenser.

 II. Excessive Noise

It is normal for the ice cream cabinet to generate a certain amount of noise during operation. However, if the noise is excessive, the cause needs to be investigated. First, check whether the ice cream cabinet is placed stably. An uneven floor can cause the compressor to resonate during operation, thus increasing the noise. You can adjust the leveling feet at the bottom of the ice cream cabinet to keep the cabinet level.

Then, check the internal fan. Noise can be generated if the fan blades are deformed, loose, or rubbing against other components. Open the door of the ice cream cabinet and observe the operation of the fan. If abnormal shaking or rubbing sounds are detected, the fan should be replaced or adjusted in a timely manner.

In addition, damage to the shock - absorbing device of the compressor may also lead to increased noise. Check whether the fixing screws of the compressor are loose and whether the shock - absorbing pads are aging or damaged. Replace them if necessary.

III. Poor Door Sealing

Poor door sealing can lead to cold air leakage, increase the energy consumption of the ice cream cabinet, and at the same time affect the cooling effect. During the inspection, after closing the door,夹 an A4 paper in the door gap. If the paper can be easily pulled out, it indicates that there is a problem with the door sealing. Check whether the sealing strip is aging, deformed, or damaged. If the above - mentioned situations occur to the sealing strip, a new sealing strip should be replaced in a timely manner. In addition, check whether the door hinge is loose. If the hinge is loose, the door will not close tightly. You can adjust the position of the door by tightening the hinge screws.

IV. Abnormal Display Panel

When problems such as unclear display, random number jumping, or no display occur on the display panel of the ice cream cabinet, first check whether the connection cable of the display panel is loose or disconnected. Open the rear cover of the ice cream cabinet and check the connection of the cable to ensure it is firmly connected. If the connection cable is normal, it may be a malfunction of the display panel or the control board. For some ice cream cabinets with a self - inspection function, you can perform a self - inspection according to the operation method in the manual to determine the location of the malfunction. If you cannot judge and repair it by yourself, it is recommended to contact a professional maintenance personnel for handling.

The above are the inspection methods for common malfunctions of desktop ice cream cabinets. If you have other questions during the inspection process or encounter more complex malfunctions, please feel free to tell me the specific situation.
