Why is frost under counter freezer?

problem found. Every time the door was opened and frost started, it was because hotter air from the outside entered the under counter freezer, and the moisture in the air then cooled and condensed. The culprit may be a poor seal around the door, but there are other reasons why your freezer is frosting:

1.      The under-counter freezer door is often opened to let warm and cold air out. The moisture in the warm air condenses and freezes, turning into frost.

2.      The door was blocked by something that prevented it from closing properly.

3.      The temperature may be set too low. The temperature setting varies depending on how much food is inside the device and how often the door is opened.

4.      The freezer is too full for normal air circulation and frost.

Solve the problem. There are only a few causes of frost in the freezer, so finding the source of the problem should be simple. Once you are done, you should be able to easily fix it yourself.Check the seal to make sure it is not cracked or damaged. If the seal is found to be damaged anywhere, replace the entire seal. Put a piece of paper between the under counter freezer and the door. You can see how much resistance it has when trying to pull it out with the door closed. The problem may be that the doors are misaligned and just need to be readjusted.Frosting may indicate a problem with the self-defrosting unit. The defrost heater may not turn on to melt the frost. Your user manual will show you what it looks like for you to troubleshoot.Defrost the underfloor freezer by closing the underfloor freezer for 24 to 48 hours. When you reopen it, check that it is working properly. If so, you need to check the defrost heater, defrost thermostat and defrost timer to see if they are all working properly.

How to prevent frost in the under counter freezer?

1.      Try not to open the underfloor freezer door. Frequently opening the door will increase the humidity inside the underfloor freezer and freezer, which may cause ice accumulation and frost. When deciding what to eat or trying to figure out what to remove, avoid opening the underfloor or freezer door. Instead, quickly list your needs to get all of them out at once. Only one door can be opened at a time. Close the door as soon as possible and within 1 minute. For example, if you want to bake, take out eggs, butter and milk all at once. This way, you only need to open the door once. If you have a hard time remembering the inventory in the under counter freezer, keep a list of the contents on the under counter freezer door.

2.      If the door hinge is loose, tighten it. Loose hinges on the under counter freezer or freezer doors can cause incomplete seals; this can increase the humidity inside the device and cause icing. If you notice that the screws on the door or hinge are shaking, use a screwdriver to turn clockwise to tighten the screws. Continue tightening them until they no longer rotate. Depending on the type of under counter freezer you are using, you may have to lift the plastic cover to expose the hinge.

3.      Wipe the seals on the inside of each door to remove any residue. Food debris or ice crystals on the gaskets of the underfloor freezer or freezer door linings will not close properly. To work on 1 door at a time, use a damp cleaning cloth and mild detergent to quickly scrub the inside of the seal. Also, clean the open frame of the under counter freezer to ensure that the gasket can sit flush with it. Wipe off any remaining moisture with a dry towel and close the door. Make sure you don't leave any moisture, as moisture may form ice crystals.

4.      Replace damaged door seals or gaskets with new door seals or gaskets. Look at the flexible rubber seals on the underside of the freezer and freezer doors. These are called under counter freezer gaskets. If either looks damaged, replace it to ensure that the door of the device is completely closed. Contact your under counter freezer manufacturer to order replacement gaskets. After getting the power, unplug the device and move all perishable items to the cooler. Unscrew the damaged gasket and screw the new gasket into place. Make sure you know the model number of the device; you will need this part to get the correct replacement part.

5.      Before reopening the under counter freezer and starting to load, test the tightness of the new gasket. It should be flush with the open frame of the under counter freezer or freezer without any gaps.

Possible causes of failure of the under counter freezer

There is frost in my under counter freezer. Possible culprit: The defrost heater needs to be replaced. Depending on where the frost is, it may be due to many correctable conditions. Frost around the gasket of the freezer door indicates that the door is not fully closed. Look for any packaging or items that may prevent the gasket from sealing properly: the food package is extended too far, the drawer is not fully sealed, the freezer is not locked, or the item is left on the top of the device. If the frost is light, it snows, and it seems to be everywhere, the freezer temperature may be set too low. If the set temperature of the device is too low, moisture cannot be removed from the air while the device is cooling. The moisture will turn into "snow" before the device begins its next cooling cycle. Make sure the freezer temperature is near 0 ° F (-18 ° C) and the under-counter freezer is near 37 ° F (3 ° C).If frost is everywhere and it freezes, the door to the under-counter freezer may be open. Initially, frost will form near the door area, but eventually it will cover the entire interior. In most cases, correcting the problem causing frost and allowing the under-counter freezer to perform several defrost cycles will remove excessive frost and the device will return to normal. Frost only on the back of the freezer section where the evaporator coil is located, indicating a problem with the defrost cycle. Depending on the device, this could be a heater, bimetal, defrost sensor, defrost timer or control board failure. Further troubleshooting is needed to find out the exact conditions required to resolve the issue.

A small amount of water leaked from the floor next to the under-counter freezer. Possible culprit: The defrost drain is frozen and needs to be defrosted and cleaned. Appliances spilling water on the floor may also be caused by melting ice cubes and drinks spilled when the cup is filled. If the device contains water and ice, the leak may come from a home connection. Check the water supply line from the shut-off valve to the under-counter freezer. Pay close attention to where the pipeline is connected to equipment and domestic valves. If water leaks anywhere, the water pipe should be replaced. Carefully check around the shut-off valve. If there is a leak anywhere, it should be replaced immediately. If you cannot do this yourself, contact a licensed plumber to replace it.

If the water comes from the freezer itself, it may be due to an overfilling of the condensation pan. This is usually due to excessive frost forming on the evaporation coil. When the freezer performs a defrost cycle, the amount of water generated exceeds the amount of water that the drain pan can hold. This may be due to high usage, especially at high humidity. Limit the number of times the underfloor freezer door opens and how long the door stays open. Before the next defrost cycle, water did not evaporate in the condensation pan. Ensure that the back room cover is in place. This allows proper airflow on the condensation pan, which will increase the rate of water evaporation. If damaged or missing, the cover needs to be replaced. If the condensate pan breaks and leaks, it needs to be repaired or replaced.

Frosting inside the underfloor freezer may not only reduce the working efficiency of the equipment, but also shorten the life of the freezer, so it is necessary to know how to defrost the ice and perform maintenance.
