The refrigerator evaporator is one part of the refrigeration cycle that makes the inside of your refrigerator cold. After the refrigerant gas has gone through the condenser coils located at the back of the refrigerator, it starts to cool down and turn into a liquid. It’s at this liquid stage that the refrigerant reaches the expansion valve. This refrigerator is intended for use in a location where the temperature ranges from a minimum of 55°F (13°C) to a maximum of 110°F (43°C). The preferred room temperature range for optimum performance, which reduces electricity usage and provides superior cooling, is between 60°F (15°C) and 90°F (32°C). 2 days ago · Using a multimeter, check for continuity.
