Serviceman Checking Temperature Of Freezer In Kitchen
My Freezer Is Running Too Cold?
Put your hands inside your refrigerator to feel whether or not you can feel a current of cold air coming out of your cooler. Refrigerators have air dams which direct the cold air directly into the freezer and refrigerator sections.
You can troubleshoot further by removing the ventilation vents where air dampers or the fridge controls are located. If the air damper on your refrigerator/freezer is not working properly, then too much cold air can remain inside your freezer rather than being circulated into other areas, such as the refrigerator. If air is blocked or closed off from above, the refrigerator must operate much longer, and freezer temperatures drop to lower levels.
If the environment is too cold, then the freezer might not have enough running time to keep the temperature. If a circulator fan is out, it typically results in longer run times and a freezer with a much lower temperature. If temperatures are too cold anyway, shift the air controls to either freezer-cold or fridge-warm.
To make sure you have a correct temperature, you must leave space to let proper airflow flow between your freezer and cooler compartments. If everything is frozen inside your freezer, it is more freezer-like than fridge-like, and your controls appear set to a certain halfway point, it is very possible this issue is not caused by an airflow issue. If your fridge has fans running, airflow seems to be freeing up inside the fridge, and the settings are set correctly, but you are still getting really cold temperatures, then it is probably due to cold-control problems.
If a sensor or thermometer is not working correctly, the electronics controls might not be properly adjusting temperatures, which allows for extra cold air to get in, freezing the food. If the root cause is a temperature sensor or thermistor, then you will need to install a new one to make sure your freezer is working correctly. The thermistor is critical for running the fans, compressor, and shock absorbers, so if your thermistor is bad, it is not sending the electronic control board the signal to turn the motor off, which is why your freezer is getting too cold and will over-freeze. If a thermistor is defective, you either have to take it out and check with a multimeter, or you have to get access and check the terminals on it on your fridges main control board.
The sensor, or thermistor, measures temperatures within the refrigerator and sends signals to a control board that may adjust air temperatures depending on those readings. If your temperature-control sensor/thermometer is malfunctioning, it cannot tell you what adjustments should be made to the fridge and freezer in order to keep it at a proper temperature.
When a temperature-control component in your primary control board is damaged, this may result in the freezer being too cold. If the thermostat passes an electrical test of functionality, but the refrigerator/freezer is still running on continuous, freezing everything, then a problem may exist with the faulty temperature sensing bulbs in the temperature control. In other words, setting high on the temperature control knob would indicate your appliance is coldest — it can make the fridge freezer too cold. If you are in an area that is often extremely cold, it is going to cause your refrigerator and freezer to get cold, so always look up your appliances optimum operating temperature on your appliances manual, and adjust your temperature control knob accordingly.
Before checking your air conditioning unit is thermostat, be sure that your fridge is set to 36 to 38 degrees F. The amount of cold air coming into your cooler is typically controlled by a damper, which, depending on your model, may either be adjusted manually or controlled automatically through the thermostat, which controls the temperature. If you have a manually controlled damper, make sure that it is slightly closed, and is not allowing too much cold air to come into the fridge. You can tell the difference between this piece and your fridges cooling controls, as there is no “off” setting on the knob controlling this damper.
Check to make sure that the damper door is not stuck in its opened position: If cold air is flowing continuously and unrestricted out of the damper, then your food will be too frozen. Make sure that your appliances controls are set at 0degF (18degC) for freezers, 37degF (3degC) for fridges. The freezer will hold the set temperature while you turn off the ice maker, rather than cooling further automatically. Then, the ice maker will go back to the setting you have and will no longer get too cold while still making ice.
Your freezer will turn off when it has reached its proper interior temperature, the thermostat is what is supposed to be monitoring that right now. Expect your freezer to remain too cold for some time, even after changing your settings. Another possible reason why the freezer is too cold may be an electrical malfunction, which causes the freezer to remain powered on, even though it is at a proper temperature.
Your refrigerators or side-by-side, top-and-bottom freezers should be keeping items within them at the ideal temperature, but sometimes, problems can occur that are causing the freezer to be too cold. When a fridge is turned off, the air from a refrigerators side-by-side freezer may move down into the refrigerators bottom, creating extremely cold temperatures and freezing vegetables and fruits stored in a crisper. Some areas of the fridge are cooler than others, particularly items stored near the freezer compartment, or near the openings, which let cold air out from the freezer. The cold-control thermostat is located in the coolers fresh produce compartment, and it controls temperature within the cooler.
The cold control will have a temperature sensor attached to it, which is located towards the rear of the compartment. There are usually two control knobs on a fridge, one is the cold control, which is a thermostat, and another knob regulates airflow between the compartments. The temperature gauge/thermometer tracks freezer and fridge temperatures, and regulates fan, ducting, and compressor accordingly.
