Freezer glass door common problems and solutions

Glass door freezer is a freezer product commonly used by supermarket users and convenience stores. Mainly used for refrigeration of milk, beverages, mineral water, etc. This freezer is designed with a glass door for a strong display.

Users can view the panorama of products in the freezer, stimulate purchase desire, and bring more revenue to the enterprise. In family life, we should master some basic maintenance methods of glass door freezers, so that we can quickly eliminate problems without delaying use. When the glass door freezer is not cooled, we can judge it from the following aspects.


1. Abnormal power connection: power failure; loose power socket; whether the power circuit breaker is disconnected.
Checking method: open the box door, check whether the light inside the box is on, or test with an electric pen.
2. If the power connection is normal, please listen to whether the compressor is working.


The compressor will emit slight vibration and motor sound during normal operation (if you feel the vibration of the compressor with your hands, you should be careful not to burn it, because the temperature of the compressor is 40-50°C in winter and 80°C at 80°C). summer -90°C).
Check whether the temperature controller is in the working equipment.

The temperature controller has a stop gear (0 gear). If it's in the stop gear, the compressor won't work. If the above items are normal, please contact the maintenance personnel.

3. Poor refrigeration in the glass door freezer
Check to see if the temperature controller is set too low. Whether the food is stored too much or overheated. Whether the door is opened frequently.

Whether there is direct sunlight or a heat source near the glass door freezer. Whether the surrounding ventilation is good. Check whether the ambient temperature is too low and the temperature compensation switch is not turned on.


4. If the compressor can work, please judge whether there is refrigerant in the refrigeration system.
Let the glass door freezer run for a few minutes, then remove the plug and listen for the sound of liquid flowing through the copper pipes. If not, it means that the refrigerant in the system has leaked, or the compressor has lost its ability to work.


5. If the glass door freezer is intercooled, please check whether the fan is working normally
Open the freezer door, press and hold the button on the edge of the box opening (this button controls the interior lighting and stops the fan when the door is opened), and check to see if the fan is working. If the fan is not working, the glass door freezer will not cool.
6. The glass door freezer cannot be started when there is noise
When the glass door freezer is started, at normal ambient temperature (15°C-38°C), if the compressor makes a "humming" sound and stops working for about half a minute, the reason is that the power supply voltage is too low (lower than 187v), Cause the compressor to fail to start; if the compressor emits a "bo" sound, you hear the "PATA" sound, which is caused by the power supply voltage being too high (higher than 242v) or the compressor being connected to the power supply.

Or the temperature of the compressor casing drops, and the glass door freezer can work normally.
7. The door is not closed tightly
The number one cause of a gap between the freezer glass door seal and the box is deformation of the door seal. The deformed concave part can be baked with an electric blower (power 300W) to restore the original state and eliminate the void.

However, the power of the blower should not be too large, the hot spots should not be too concentrated, and the blower should not be too close to the deformed door seal, otherwise the door seal will be damaged. Also, filling a thin sponge under the juncture between the recessed part of the door seal and the door will eliminate the void. If the above correction is invalid, please replace it with a new correction.


8. Water or overflow in the refrigerator
The drain holes in the refrigerator compartment are blocked, preventing the condensed water from draining smoothly. Some kind of flexible tool can be used for dredging.
If you have any undiagnosed problems, please seek professional repair experts.
