Issues related to the defrost system condenser tubes that are dirty fan failures, gasket leaks could cause the Viking freezer to fail to get sufficiently cold. Although you may notice the cooling problem in the freezer however, the Viking freezer or refrigerator will not be as cool. To prevent food from spoiling it is essential to swiftly solve the issue.
How to stop air leaks from making your Viking freezer too cold
If your Viking freezer becomes too warm to be able to freeze ice cream and there is lots of frost, then warm, humid air could be entering the refrigerator. Examine all gaskets on the door for damage and replace damaged door gaskets. If gaskets are in good condition however a door is moving on its hinges, creating gaps between the gasket and the cabinet within door openings, you can adjust the hinges of your Viking refrigerator to ensure that gaskets be sealed to the cabinet. If frost is only visible on the wall of the back freezer, the automatic defrost may be failing.
If it is functioning properly, the defrost system melts the frost off the evaporator coils every eight hours or so to ensure that the air passageways through the evaporator clear so the refrigerator and freezer compartments cool properly. The defrost mechanism that is automatic can fail, and frost will accumulate on the evaporator and back freezer compartment walls. The accumulation of frost could block cooling air pathways through evaporator, causing Viking freezer to not cool down well.
What can you do to fix other issues that stop your freezer getting cold enough If the evaporator fan stops working, you should check for cooling inside of the freezer compartment. If it isn’t working properly you should replace the fan. Problems with cooling can be caused by dirty condenser coils. Unplug the Viking refrigerator and check the condenser coils for dust or dirt buildup.
If they are dirty, clean the condenser tubes. Keep cleaning the coils during regular maintenance of your Viking refrigerator. If the freezer is not being cold enough, make sure that the condenser fan running. If the fan stops running, the condenser will not cool refrigerant efficiently. Replace the condenser fan if it isn’t running when it is activated. These repairs can help resolve your refrigerator problems.
Replace the Viking refrigerator defrost sensor
The Viking refrigerator defrost sensor, also referred to as the bi-metal defrost termination thermostat-strikes when it senses that the temperature of the evaporator getting hot enough that it might overheat. The sensor for defrost will go off if it detects that the temperature in the evaporator has been too hot and will shut off the heater. If the defrost sensors trips due to a problem with its operation, then there is a chance that frost will build up on the fins of the evaporator. This can cause the refrigerator and freezer to fail to cool as efficiently. The volt/ohmmeter is a tool to verify continuity of the defrost sensors. Replace the sensor if it shows no continuity around 0° F.
Clean the Viking condenser coils of the refrigerator:
Dust-covered Viking refrigerator coils could prevent the Viking refrigerator and freezer from running effectively and efficiently cooling. Follow the steps in the owner’s manual to cleaning the condenser coils. Before you are able to get access to and clean the coils in the Viking refrigerator, disconnect the appliance. The coils can be found behind most Viking refrigerators. It is possible to remove the condenser tube with brushes. Replace the Viking refrigerator condenser fan: The condenser fan is in the machine compartment of the Viking refrigerator next to the compressor. The fan moves air through the coils of condenser coils, cooling the refrigerant. When refrigerant is moved through the expansion device, it’s cool. Replace any defective condenser fan.
Repair the Viking refrigerator freezer defrost:
In order to improve heat exchange in the Viking refrigerator’s auto defrost is able to melt frost from evaporator. The compressor stops and the heating element switches on, and the it melts away the evaporator fins. Condensate is pumped into an evaporator drip pan below the evaporator. It then is pumped through a drain tube and into the drain tray that is next to the machine compartment. Before the next cycle of defrost the condensate water is evaporated out of the drain pan. If the defrost process fails, diagnose and repair the problem. Replace the Viking refrigerator-evaporator fan. The fan is connected to the evaporator. It circulates air throughout the cabinet in order to cool the unit. If the fan ceases to function then replace it. Replace the Viking refrigerator’s temperature control board. The temperature control, also known as an electronic control board is situated inside the machine chamber adjacent to the compressor. It is located behind a panel at the the back of Viking refrigerator. The temperature control board controls the compressor, as well as other major components within the Viking fridge.
The tech sheet provides specific diagnostic methods to check the board. If the board for controlling temperature fails to function properly or it stops functioning, replace it. Change the Viking refrigerator thermostat temperature control thermostat. The thermostat is also called the cold control thermostat or the cold thermostat. It is located inside the housing for the control. The thermostat has a sensor tube which detects the temperature in the Viking refrigerator. The temperature of the cabinet is controlled by the thermostat that controls temperature. It switches off and on the compressor according to the temperature that is detected by the sensor tube. Replace the temperature control thermostat if it fails to sense temperature correctly or does not cycle the compressor correctly.
The Viking refrigerator’s thermistor needs to be replaced. The thermostat gets information about temperature from the thermistor, so a damaged thermistor might provide false information. Replace the Viking refrigerator defrost timer: The defrost timer can be described as an electronic device that controls the intervals between defrost cycles that are automated within the Viking refrigerator. The defrost motor drives the control elements and drives them. The defrost motor ceases to run when the control contacts of the device are in defrost state. When the compressor has stopped, the heater turns on for the time specified to melt frost off the fins of the evaporator. This increases heat exchange efficiency across the evaporator. The defrost timer contacts will turn back after the timer expires so that normal cooling can continue to the Viking refrigerator. You’ll need to replace the defrost timer if it doesn’t advance when activated. The timer’s contacts are not working properly. could cause the heater to not be energized at all or constantly energize. In such cases, you should change the timer. Adjust the door of the freezer or refrigerator. The hinges of the doors to freezer and refrigerator can be damaged or bent.
Doors can start to sag and allow warm moisture to flow into the fridge. This creates excess frost which can cause the drain tube to freeze or freezer to freeze. Repairing the refrigerator involves aligning and fixing the hinges in order to ensure they function properly. Repair the Viking refrigerator door gasket: The gasket for the door is attached to the refrigerator or freezer door panel and prevents air from entering or escaping the cabinet when the door is shut. If the door is shut the gasket can become worn and permit warm, humid, air to get into the fridge. This can lead to cooling issues and excessive frost. If it is damaged or ripped, you can replace the door seal.
Replace the Viking refrigerator electrical control board. It detects that the refrigerator’s compressor must be running in order to keep it cool and then sends out voltage to the compressor fans. To keep track of the temperatures inside the refrigerator or freezer, the control panel’s electronic circuit receives signals via temperature sensors. The control board’s electronic circuitry regulates the process of defrost using this information.
The electronic control boards can usually be checked for any faults to check if they’re functioning properly. While the test may differ according to the model, the most common one is the Forced Defrost. You can find the instructions on how to run tests in the tech sheet. If your electronic control board isn’t functioning properly, you can replace it. Maintenance routine for Viking refrigerators Clean refrigerator coils cause problems with the freezer and refrigerator’s ability to cool properly and operate efficiently. For cleaning condenser coils, consult the owner’s manual.
Unplug the Viking refrigerator prior to accessing and cleaning the coils. The coils can be found in the bottom of the refrigerator’s grill. Clean the condenser coils with the help of a coil brush. Additional routine maintenance includes changing the water filter, washing the dust from the bottom front grille and making adjustments to the hinges if doors don’t seal tightly and emptying the water from the drain pan.
