Solution: Set your refrigerator’s thermostat anywhere from 33–40°F (0–4°C), and your freezer’s thermostat to 0°F (-18°C). Give both compartments 24 hours to establish their new temperature and begin to thaw the ice maker and inlet tube. This video from Sears PartsDirect shows how to replace a defrost bi-metal thermostat in a top-freezer refrigerator. The defrost sensors shut off the defrost The condensing unit, which acts as the brain of your refrigerator/freezer, is controlled by a thermostat. The thermostat, like the one used in your home, can be set to keep a consistent temperature. If using the refrigeration box as a refrigerator, the temperature should be kept above freezing (32 degrees Fahrenheit). 12. Compressor The function of a compressor is to increase the pressure, and corresponding saturation temperature (boiling point) of the refrigerant vapor to high enough level so the refrigerant can condense by rejecting its heat through the condenser. Types Hermetic motor, hermetic compressor A hermetic or sealed compressor is one in which both compressor and motor are confined in a single If you have a C wire, place it into the C terminal on your wall plate. C wire adapters are available here. Let’s look at the G wire. This wire goes to the G terminal on your new thermostat. Of the Y, Y1, and Y2 wires, Y or Y1 go to the Y terminal and Y2 to the Y2 terminal. The O/B wire can have many configurations. . If the set temperature (on the thermostat) is reached within the refrigerator, the thermostat shuts down the power supply to the compressor. This results in a reduction of temperature in the refrigerator. To this end, you may have observed a stoppage in the function of the refrigerator (similar to muting a sound). Thus a cooling effect is created in the working fluid. And this decreases the temperature inside the refrigerator. When a predetermined value of the temperature is achieved inside the refrigerator, thermostat switch operates and disconnects the compressor motor from the electric supply. Further circulation of refrigerant and its cooling effect A broken thermostat is one of the most common reasons everything in a refrigerator freezes. The thermostat maintains the temperature inside the fridge and ensures it stays within a predetermined range. If the thermostat malfunctions, the refrigerator may get colder than it should and freeze the interior. Now crimp the other butt connector down on the other wire. Attach each connector to the corresponding wire in the refrigerator and crimp them down. Reattach the new defrost thermostat onto the evaporator coil in the same place the old one was clipped. Then push the wires up and out of the way. Reinstall the back panel. Remove the defrost bi-metal thermostat. Unplug the defrost bi-metal thermostat wires. Unclip the defrost bi-metal thermostat and remove it. Tip: The aluminum fins of the evaporator are sharp. Wear work gloves to protect your hands. PHOTO: Unplug the wires.
