In this guide, we’ll walk you through a crucial Viking freestanding refrigerator repair, and the step-by-step process of how to replace a faulty Viking Freestanding Refrigerator thermostat. Whether you’re a seasoned DIY enthusiast or just looking to save some money on repairs, this tutorial is for you. 

Let’s get started!

Understanding the Function of the Thermostat in a Viking Freestanding Refrigerator

The thermostat in your Viking freestanding refrigerator plays a significant role in maintaining the ideal temperature. It acts as a control mechanism, ensuring the refrigerator cools to the desired level and keeps your food fresh.

The thermostat also monitors the temperature inside the refrigerator and signals the cooling system to turn on or off as needed. Once the temperature inside rises above the set point, it sends a signal to activate the compressor, initiating the cooling cycle. 

Once it reaches the desired level, the thermostat instructs the compressor to shut off, conserving energy until the temperature rises again.

Preparing for the Replacement: Safety Precautions and Necessary Tools

Before replacing a refrigerator thermostat and any Viking freestanding fridge repair, it’s important to take some safety precautions and gather the necessary tools. Doing so can ensure a smooth and secure repair experience. Here’s what you need to do:

  • Safety first: Unplug the refrigerator from the power source before starting any repair work. 
  • Gather the tools: You’ll need a few essential tools. These typically include a flathead screwdriver, a Phillips screwdriver, pliers, and a multimeter to test electrical connections. 
  • Obtain the replacement thermostat: Identify the model number of your Viking freestanding refrigerator and locate a compatible replacement. 
  • Review the manufacturer’s instructions: Take the time to review the manufacturer’s instructions for replacing the thermostat. 
  • Wear protective gear: It’s advisable to wear protective gloves and safety glasses during the repair process. 

Locating the Thermostat: Identifying its Position in the Refrigerator

The thermostat in a Viking freestanding refrigerator is typically located on the control panel or temperature adjustment area inside the refrigerator compartment. It is commonly positioned near the top or side of the refrigerator. 

Look for the control panel where temperature settings are displayed, and you should find the thermostat nearby. It may have visible wiring or sensor connections. 

Consult your owner’s manual or contact Viking refrigerator customer service for precise information about your specific refrigerator model.


Disconnecting the Power and Removing the Thermostat Cover

Once you’ve cut off the power to your refrigerator, it’s time to remove the thermostat cover. Follow these steps: 

  • Remove the thermostat cover: Using a screwdriver (usually a Phillips or flathead screwdriver), remove the thermostat cover by removing the screws. Set aside the screws in a place where it’s safe from being misplaced. 
  • Lift the cover: Gently lift and remove the thermostat cover from its position. Be cautious not to damage any wires or other components connected to the cover.
  • Examine the wires: Take a moment to examine the wires, noting their arrangement and connections (for installation reference.)

Detaching and Replacing the Faulty Thermostat

After disconnecting the power and removing the thermostat cover, it’s time to detach and replace the faulty thermostat in your Viking freestanding refrigerator. Follow these step-by-step instructions:

  • Disconnect the wires: Using pliers or your fingers, carefully detach the wires from the terminals of the old thermostat. Gently pull the wires away from the terminals, preventing any damage. 
  • Label the wires: Label them with tape or take a picture for reference when connecting them to the new thermostat.
  • Remove the old thermostat: Locate the mounting screws or clips that secure the old thermostat in place. Use the right tools, like a screwdriver, to loosen and remove these screws or clips. Once detached, carefully take out the old thermostat from its position.

Installing the new thermostat: 

Now, it’s time to install the new thermostat designed for your Viking freestanding refrigerator: 

  • Install the new thermostat: Position the new thermostat in the same spot where the old thermostat was removed. Make sure it aligns properly with the mounting holes or clips.
  • Connect the wires to the new thermostat: Refer to the labels you wrote or notes you took earlier to correctly connect the wires to the corresponding terminals on the new thermostat. 
  • Secure connections: Ensure a secure connection by firmly attaching each wire to its designated terminal. Once the wires are connected, use the mounting screws or clips to fasten the new thermostat in place securely. Ensure the thermostat is snug and properly aligned with the control panel.

Reassembling the Thermostat Cover and Restoring the Power

With the faulty thermostat successfully detached and replaced, you’re one step closer to restoring the optimal functionality of your Viking freestanding refrigerator.

Carefully place the thermostat cover back over the new thermostat. Align it properly with the screw holes, and using the screws you set aside earlier, tighten them to secure the cover in place.

Testing and Calibration: Verifying the Functionality of the New Thermostat

After successfully replacing the faulty thermostat in your Viking freestanding refrigerator, testing and calibrating the new thermostat is essential to ensure its proper functionality. Follow these steps to verify that the refrigerator is maintaining the desired temperature:

  • Set the temperature: Adjust the temperature settings on the control panel to the desired level. Typically, you can use a dial or digital controls to set the temperature.
  • Allow time for stabilization: Give the refrigerator some time to stabilize and reach the desired temperature. This whole process may take you up to a few hours, so be patient.
  • Monitor the temperature: Use a thermometer to check the temperature inside the refrigerator. Place the thermometer in a central location and ensure it accurately reflects the temperature.
  • Observe consistent cooling: Monitor the refrigerator’s cooling performance for several hours. Check if the temperature remains consistent within the desired range. Listen for the compressor cycling on and off as needed.

Calibration adjustments (if necessary): 

If you notice any temperature discrepancies or the refrigerator fails to maintain the desired temperature, you may need to calibrate the thermostat. Refer to the manufacturer’s instructions or consult a professional Viking refrigerator repair service technician for guidance. 

Finally, do final checks. Double-check that all connections are secure, the thermostat cover is properly fastened, and there are no signs of any wiring issues or malfunctions.

Troubleshooting Tips: Addressing Common Issues After Thermostat Replacement

After replacing the thermostat in your Viking freestanding refrigerator, you may encounter some common issues that require further troubleshooting and may require the help of a professional Viking freestanding refrigerator repair service technician.
