With all the extra running---are you getting frozen items in the fresh food section?? You have to understand that if the refrigerator was running all the time and for instance had a stuck on temperature control, you would be getting frozen items like lettuce, eggs, etc in the fresh food section. If that is not happening then the refrigerator needs to run until the cold control turns it off. Set both controls to the middle setting and let it run without playing with it for 24 hours and see if it turns off on its own. Frost free refrigerators average run times of 50% to 75% on time depending on how warm the room temperature actually is. If after 24 hours it is still running and some of your Fresh food is freezing then you do have a bad temp control.
If the refrigerator was tipped on back or side, even part way, it has to wit upright at least overnight, because of the freon flowing upward. If you just moved in and it has been sitting and unplugged, then it may be low on freon.
Here are some tips
If you open the fresh food compartment of your fridge (the
non-freezer compartment), you will most likely see two different
controls. One refers to the refrigerator temperature and the other
refers to the freezer. Different manufacturers use different wording,
but the idea is the same.
The first thing you need to know in order to understand what these
controls really do is that all the cold air in the entire refrigerator
is made in the freezer compartment. A portion of that cold air is then
blown into the fresh food compartment. How much cold air gets blown in
is controlled by the "freezer" control, which is really just an air
baffle that opens or closed to let more or less air into the fresh food
compartment. The "refrigerator" control is actually a thermostat that
feels the temperature inside the fresh food compartment and turns the
compressor on and off according to the temperature that the thermostat
Let’s run through an example. Suppose you decide that your ice cream
isn’t hard enough. You adjust the "freezer" control to make your
freezer colder. What you’re actually doing is restricting the amount of
cold air that gets blown from the freezer into the fresh food
compartment and so keeping more of the cold air in the freezer. As a
result, the freezer will get colder but also the fresh food compartment
will tend to get warmer because its cold air supply has been
diminished. The "refrigerator" control (the thermostat) will feel this
increase in temperature inside the fresh food compartment and will keep
the compressor running longer in order to maintain the temperature
setting on the "refrigerator" control. So, you can see that any change
you make to one control will affect the other.
Many people then wonder, "Well, how do I know what the correct
setting on the controls should be?" Since the temperature inside a
refrigerator will vary according to lots of external factors such as
frequency and duration of door openings, it is impossible to say where
your controls should be set all the time in order to maintain a desired
temperature in the freezer and fresh food compartments without knowing
the actual temperature inside both compartments. For this
reason, you should place two thermometers in your refrigerator: one in
the fresh food compartment (the big one) and the other in your freezer.
The controls should then be adjusted to achieve -10 to +10ºF in the
freezer and between 36 and 38ºF in the fresh food compartment.
Keep in mind, too, that it takes 24 hours for any change in the
controls to work through the system and reach steady state so don’t
look for instantaneous changes in temperature when you make control
setting changes. Knowing the actual temperature inside your
refrigerator compartments is also a great way to save money on your
power bill since you can adjust the controls to avoid running your
compressor longer than needed to keep your food cold.
Many residential refrigerator / freezers are designed to work at temperature considerably above above freezing. Most modern refrigerator / freezer have a single electric thermostat - located in the fresh food compartment. This lone thermostat will control the compressor to keep the fridge (fresh food) section at the desired temperature (usually between 34 - 38 degrees F). The freezer will get colder regardless of how cold it is already whenever the fridge thermostat turns the compressor on.
Now that you see how the thermostat works, let's look at what happens when the fridge is placed in an unheated space - like a garage. In winter time, the temperature can drop considerably below 38 degrees. If the outdoor temperature remains cold enough, for long enough - it will affect the thermostat in the fridge. The temperature inside the fridge could drop below 38 degrees, preventing the thermostat from telling the compressor to turn on. Meanwhile, the temperature in the freezer compartment slowly rises from the normal -10 to 0 F degrees. It will continue to rise until it is the same temperature as the fresh food compartment or until the thermostat in the fresh food compartment tells the compressor to turn on again. This means the freezer contents will thaw.
If the temperature in the garage is even in the 40 to 50 degree range, the loss of cold in the fridge may not happen often enough to keep the compressor coming on often enough to keep some freezer items frozen solid - such as ice cream. Remember, water freezes at 32 degrees F, other products may require lower temperatures to remain frozen, and could thaw at 28 or other temperature.
You want to check a couple things. 1. Look inside the freezer. Is the freezer fan running? 2. If the freezer fan is running check the air vents. Remove the food from the freezer. Remove the bottom freezer liner panel to access the air vent in the rear center of the freezer. It will be frozen closed with ice. Defrost it with a hair dryer. 3. Make sure all dial settings are set at their mid-points.
Move the frozen food into the refrigerator side and turn off the freezer. Leave the door open to help it thaw quicker. A blow dryer helps to speed things up. When the line thaws, turn the freezer back on and move the frozen food back over. I am curious why it froze. Was the freezer temperature set too low or has anyone been inside the door to move the water line or insulation???
check in the freezer section for a knob to control the freezer. Turn this knob back to center and return refrigerator setting to 5. What is happening is the freezer control is just a baffle that divides the air flow into the fresh food and freezer section. If the freezer knob is turn to 1 or cold it is sending all the cold air into the refrigerator, then when you turn down the actual cold control, the system isn't allowed to run long enough to allow the freezer to stay frozen.
Refrigerator operation is controlled by the internal temperature . When there is very little ambient heat available to leak in to cause it to cycle more frequently and there is no door traffic to be a heat source the freezer temperature will increase. Keep the room heated to a higher temperature or remove frozen products is the answer. A small chest type freezer will keep food frozen while you are away and have the heat turned down.
Adjust the temperature control for the freezer to a normal setting. Fast freeze is only for when new products are put in that need to be frozen. This locks the system into a continuous run mode and could be responsible for the freezing condition in the refrigerator section. Check the temperatures with a thermometer as the sensor for the freezer temperature could be bad causing the light to come on.
