Viking Refrigerator Freezer not cooling enough - How to eliminate?

There are several reasons why your refrigerator is not cooling properly. In fact, accurate diagnostics may take too much time if the owner does not have necessary tools and experience. Pay attention to the following items. Make sure the thermostat hasn’t been turned way down by mistake. Rotate the dial from the lowest setting to the highest setting until the moment when you hear a click. The air vents have to be free for cold air to circulate. Move the items (boxes of ice cream, pizza or frozen vegetables) that may block the vents from proper operation away. Do not place food or containers in front of the vents to prevent the not cooling issue in the future. The coils collect dust and dirt (especially if you have a pet) causing poor cooling inside the refrigerator and freezer compartment. Clean the coils using the vacuum. The condenser coils are usually located at the bottom of the appliance and the evaporator coils normally found behind the rear panel. Make sure the condenser fan spins freely. If something is stuck in the fan, unplug your fridge and then pull it out. As a next step, clean the fan blades and spin the fan by hand. Finally, plug in the fridge and make sure the fan runs properly when the compressor is running. Nevertheless, it is required to check if your refrigerator needs Freon. To tell if your refrigerator needs more Freon, simply unplug the refrigerator, turn off the temperature control and place your ear on the side of the unit. A hissing or gurgling sound indicates that Freon is present. However if you hear nothing it’s likely that your fridge may be low on Freon. This can cause your fridge not to function in the way it’s intended. Freon flows through the coils on the inside and outside of your fridge, known as the evaporator and condenser coils. Before attempting to add additional refrigerant to your fridge, you’ll firstly need to check which type of refrigerant your refrigerator uses. As adding the wrong type of refrigerant could cause permanent damage to your refrigerator. To find out exactly which type of refrigerant your fridge is using, check the operating instructions which can normally be found on a sticker, on the back of your fridge or compressor. Alternatively, this information can be found within the user manual. Still, we strongly do not recommend adding Freon on your own. Don't hesitate to arrange a professional visit.
