Discovering the intricacies of your Viking VCBB36 refrigerator requires skillful navigation. One crucial task that may arise is removing the back evaporator cover, a component that safeguards the cooling system. Embark on this endeavor with a methodical approach, ensuring that you follow each step with precision and care. By understanding the proper techniques and employing the appropriate tools, you can confidently tackle this undertaking and restore your refrigerator to optimal performance.
As you prepare to remove the back evaporator cover, gather the necessary materials to facilitate a seamless process. A flat-head screwdriver, a Phillips-head screwdriver, and a putty knife are essential tools for this task. Additionally, don’t forget to wear gloves for protection and a dust mask to minimize the inhalation of dust particles. With these tools and safety precautions in place, you can proceed with confidence towards the successful removal of the back evaporator cover.
Before you begin the removal process, ensure that the refrigerator is unplugged and disconnected from the power source. This safety measure will prevent any electrical hazards and ensure a safe working environment. With the power disconnected, locate the screws that secure the back evaporator cover. These screws are typically situated at the top and sides of the cover. Using the appropriate screwdriver, carefully remove these screws, taking note of their size and location for proper reassembly later. Once all screws have been removed, gently pull the cover towards you, using the putty knife to assist in detaching it from any adhesive or sealant that may be present.
4. Removing the Back Evaporator Cover
Now, let’s focus on the back evaporator cover. It’s usually secured by screws, so you’ll need a screwdriver to remove them. Here’s a detailed breakdown of the process:
a) Locate the Screws
Locate the screws that hold the back evaporator cover in place. They are typically positioned around the perimeter of the cover.
b) Remove the Screws
Using the appropriate screwdriver, carefully remove the screws. Ensure you keep track of them for reassembly later.
c) Lift and Slide Off the Cover
Once all the screws are removed, carefully lift the back evaporator cover and slide it forward. It may be slightly stuck, so use gentle force to detach it.
d) Inspect and Clean the Cover
Take this opportunity to inspect the back evaporator cover for any visible damage or buildup. If there are any obstructions or debris, use a soft cloth or brush to remove them gently.
e) Reassemble the Cover
Once the cover is clean, align it carefully over the evaporator coil and slide it back into place. Make sure it fits snugly against the coil.
f) Install the Screws
Secure the back evaporator cover by reinstalling the screws. Tighten them firmly but avoid overtightening.
g) Reconnect the Electrical Wiring
Reconnect the electrical wiring to the compressor unit following the same procedure as before. Ensure all connections are secure and insulated properly.
h) Test the Unit
Turn on the refrigerator and allow it to run for a few minutes. Check if the compressor is operating properly and that the refrigerator is cooling effectively. If everything is working as expected, you have successfully removed and reattached the back evaporator cover.
Troubleshooting Common Removal Issues
Unable to Locate Screws
If you’re unable to locate the screws, they may be hidden beneath the plastic cover. Use a thin tool to gently pry open the cover and expose the screws.
Screws Won’t Turn
If the screws won’t turn, they may be rusted or stripped. Try using a penetrating oil to loosen them. If that doesn’t work, you may need to use a screw extractor.
Cover Won’t Come Off
If the cover won’t come off, it may be stuck in place by ice buildup. Try using a hairdryer to melt the ice and loosen the cover.
Broken Screws
If you break a screw while removing the cover, don’t panic. You can still remove the cover by drilling out the broken screws and replacing them with new ones.
Stripped Screw Holes
If the screw holes are stripped, you may need to use a larger screw or a screw anchor to secure the cover in place.
Cover Damaged During Removal
If you damage the cover during removal, you may be able to repair it with a plastic epoxy. If the damage is extensive, you may need to replace the cover.

Cleaning and Inspecting the Back Evaporator Cover
Regular cleaning and inspection of the back evaporator cover are essential to maintain the optimal performance of your Viking VCBB36. Here’s a detailed guide:
1. Disconnect the Refrigerator from Power
Unplug the refrigerator from the wall outlet to ensure safety during the cleaning process.
2. Remove the Back Panel
Locate the screws at the bottom of the back panel and remove them using a screwdriver. Carefully lift off the back panel.
3. Remove the Evaporator Cover
Inside the back panel, locate the screws securing the back evaporator cover. Remove the screws and carefully lift the cover off.
4. Clean the Evaporator Cover
Use a damp cloth to wipe away any dust or debris from the evaporator cover. If there is significant grime buildup, consider using a mild detergent solution. Rinse the cover thoroughly and allow it to dry completely.
5. Inspect the Evaporator Coil
Once the cover is removed, inspect the evaporator coil visible behind it. Check for any ice buildup or blockages that may hinder airflow. If necessary, use a soft brush to remove any debris.
6. Clean the Fan Blades
If the evaporator fan is visible, use a vacuum cleaner or a damp cloth to remove any dust or debris from the fan blades. This will help ensure proper air circulation.
7. Check the Drain Pan
Locate the drain pan located below the evaporator coil. Inspect it for any standing water or blockages. If necessary, clean the pan and ensure the drain hole is clear.
8. Inspect the Electrical Components
Examine the electrical components such as wires and connections for any damage or loose connections. If you notice any issues, consult a qualified technician for repair.
9. Reassemble the Evaporator Cover and Back Panel
Once everything is clean and inspected, carefully reassemble the evaporator cover and back panel in reverse order. Secure the screws tightly and reconnect the refrigerator to power.
Step 4: Reinstalling the Back Evaporator Cover
Once the back evaporator cover is clean, it’s time to reinstall it. Follow these steps to ensure a proper fit and prevent any issues with your refrigerator’s performance:
9. Align the Evaporator Cover
With the screw holes on the cover aligned with the holes on the refrigerator’s interior, gently push the cover back into place. Use a small amount of force to ensure it fits snugly.
To assist with alignment, refer to the table below for specific measurements between the evaporator cover and key points on the refrigerator’s interior.
| Measurement | Distance |
|---|---|
| Left Side Gap | 1/4 inch |
| Right Side Gap | 1/4 inch |
| Top Gap | 1/2 inch |
These measurements will help ensure that the back evaporator cover is installed correctly and fits seamlessly with the refrigerator’s interior.
Post-Removal Maintenance and Safety Checks
Cleaning the Evaporator Cover
Wipe down the evaporator cover with a damp cloth to remove any dirt or debris. Allow it to air dry completely before reinstalling.
Inspecting the Evaporator Coils
Check the evaporator coils for any signs of damage, such as dents, cracks, or corrosion. If any damage is found, it’s important to have the coils replaced by a qualified technician.
Cleaning the Condenser Coils
Use a condenser coil cleaning brush to gently remove any dust or debris from the condenser coils. Avoid using excessive force or water, as this could damage the coils.
Checking Electrical Connections
Inspect the electrical connections for the evaporator and condenser fans. Ensure that all connections are secure and free of any corrosion or damage.
Testing the Thermostat
Place a thermometer in the refrigerator and freezer compartments. Set the thermostat to the desired temperature and allow it to run for several hours. Check the temperature readings to ensure that the thermostat is functioning properly.
Checking Door Gaskets
Inspect the door gaskets for any tears or gaps. If any damage is found, it’s important to replace the gaskets to prevent warm air from leaking into the refrigerator and freezer compartments.
