The under-counter freezer is relatively not as well known as the box-type freezer. Many consumers will ask, what should be done when the under-counter freezer has a problem during work? Is it normal for the underfloor freezer to run all the time?
How to organize the under counter freezer
How do I fix a problem under counter freezer?
Remove everything and throw away old food. Even in an under-counter freezer, food doesn't last forever. The old frozen hamburger that has been around for the past ten years is a popsicle from last summer, and you may not even know everything in the freezer until you get everything on the counter. Throw away food that is too frozen (discolored and covered with ice crystals) and things you will never eat. Even if it is safe to eat frozen food, it does not taste good. Once your under counter chiller is empty, this is a great opportunity to remove any drips or spills.
Remove items from the under counter freezer to save space. You have no reason to store items in the box you purchased. If the box is already open, repack the food in a sealed container to prevent the under counter freezer from being burned. You can use a vacuum sealer or carefully squeeze the air out of the bag. Leave about 1/2 ~ 1 headspace inches (1.3 to 2.5 cm) of frozen food, so you don't want to damage the container when expanding. If you want to use a cooking instruction box, you can always cut out and paste the instructions on the container, write down the instructions on the label, or find the instructions online later.
Freeze the items to make them more suitable. You can freeze items flat in gallon or quart-sized bags. First, put your food (such as soup or minced meat) in a freezer bag and remove all air. Frozen it flat in an under counter chiller. After freezing it flat, you can stack it vertically and place it in a box or magazine rack. Your under counter chiller will be organized like a filing cabinet. Tag all containers with content and date. It's easy to forget what's behind the under counter freezer under the counter and pull it out a few months later without knowing what it is. Before freezing the container with the contents of the container, the date of freezing, and when the food should be consumed, label the container to preserve your future self. You can use a special labeling machine or simply apply some blue tape to the outside of the container and write with a permanent marker. Make sure your labels are facing out so you don't have to struggle to figure out when to eat from the under-counter freezer.
Temperature control or thermostat. If the under counter freezer is not turned off even if the required internal temperature is reached, there may be a problem with the temperature control thermostat. Rotating dial thermostats or temperature controllers use capillary and light bulb sensors that are attached to the lining of the under counter freezer to monitor temperature and also have a set of internal electrical contacts that power the compressor circuit. As the temperature of the sensor drops, the pressure on the control changes and the switch contacts will open and close the compressor. If the contacts are welded or stuck, or the sensor bulb is damaged, the compressor will continue to operate regardless of temperature. Before replacing the controls, check the sensor bulb to ensure that it is positioned correctly.
Defrost timer. If your under counter chiller is a frost-free model and can continue to run but the temperature is not high enough, there may be a problem with the defrost timer. These models use a defrost heater to melt any frost that has accumulated on the evaporator coil. The defrost timer is part of this circuit and the heater cycle should be turned on periodically to maintain a frost-free evaporator. If the defrost timer fails, the heater may not be energized and the evaporator will be blocked by frost or ice. This will cause the compressor to run almost continuously in an attempt to maintain the set temperature. You can manually advance the defrost timer to start the defrost cycle, and if the evaporator defrosts normally, you need to replace the timer.
Defrost thermostat. If your under counter chiller is a frost-free model and can continue to run but the temperature is not low enough, the defrost thermostat may be defective. These models use a defrost heater to melt any frost that has accumulated on the evaporator coil. The defrost thermostat is part of this circuit and terminates the defrost cycle when the heater melts the frost of the evaporator. The defrost thermostat should be continuous when it is at the freezing point temperature, and the open circuit state should be changed when the temperature rises above about 50 degrees Fahrenheit. If the thermostat is not continuous, the heater will not be able to be energized, and the evaporator will be blocked by frost or ice, which will cause the temperature of the underfloor freezer to rise.
User control or electronic display board number. If the under counter freezer is not turned off even if the required internal temperature is reached, and your model has an electronic display, there may be a problem with the user-controlled display panel. On some models, this electronic control is used to display, monitor and adjust the internal temperature of the freezer, and to control the operation of the compressor, evaporator fan motor and defrost heater circuit. Failure to control may cause the motor circuits of the compressor and evaporator fan to continue to conduct. Before condemning the control, the thermistor temperature sensor should also be checked for malfunctions.
Defrost heater. If your under counter freezer is a frost-free model and can continue to run but the temperature is not low enough, the defrost heater may be malfunctioning. These models use a defrost heater to melt the accumulated frost on the evaporator coil. The defrost timer turns on the heater at regular intervals to keep the frost-free evaporator. If the heater fails, frost will continue to build up on the evaporator until it is blocked and there is no air circulation. This will cause the compressor to run almost continuously in an attempt to meet the requirements of thermostat control. You can test the continuity of the defrost heater with a multimeter, it should usually show less than 30 ohms.
