Because the food within your refrigerator will get cooler and cooler it radiates less warmth towards the air within the refrigerator. The environment temperature within the refrigerator will stay cooler because this process happens. To manage the temperature inside most fridges and freezers whether thermostat can be used or perhaps a thermistor/control board combination.
Thermostat Operation
A thermostat known as a chilly-control will cycle the compressor off and on to help keep the temperature within the refrigerator inside a specified range. Typical climate configurations on most fridges is going to be around 45 F. You could adjust the new-food temperature setting by turning the dials around the cold control. Most cold-controls on Whirlpool, Maytag, Whirlpool, and General electric fridges are situated within the fresh-food side from the refrigerator, top and front close to the interior light.
Thermistor/Control Board
A thermistor is definitely an electrical device which changes resistance when a general change in temperature happens. Thermistors are usually mounted inside walls from the fresh-food compartment, as well as the freezer compartment. The thermistor is connected electric towards the control board circuit. The firmware within the control board was created to ensure that resistance from the thermistor will match confirmed temperature and can adjust fan speed, fresh-food damper door, and compressor operation to offer the set temperature.
Of all Whirlpool, Kenmore, Maytag, and General electric fridges all of the cold air for the fresh-food compartment and also the freezer compartment is created by one evaporator, that is situated behind the trunk interior panel from the freezer compartment. Because the freezer air is really much cooler compared to fresh-food compartment, you can easily understand why it's logical to make use of that one evaporator to supply the required cold air for the freezer and fresh-food compartments on most fridges.
The majority of the cold air that's created through the freezer/refrigerator evaporator moves within the freezer compartment through the evaporator fan. The evaporator fan also moves air towards the ice maker and thru the damper door to supply cold air towards the refrigerator. The majority of the damper door devices are situated within the rear-top-left from the fresh foods compartment. Only a tiny bit of cold air necessary for the meals compartment to help keep it lower towards the proper temperature therefore the damper door will close once the proper temperatures are arrived at. The control with this damper door may be the other of these two dials in your refrigerator cold control or perhaps is modified via control board interface.
