How to Adjust the Height of Doors on the B422D 

Adjusting the doors ' height can be a crucial step when it comes to ensuring the proper alignment and functionality of the B422D. Misaligned doors can affect the sealing and overall performance of the appliance. Here’s a step-by-step guide on adjusting the door height on the B422D.

1. Check Door Alignment

The first step in adjusting the door height is to determine which door is misaligned. Inspect whether the left door is higher than the right door or vice versa.

2. Left Door Adjustment

• Inspect Hinges: If the left door is higher, check whether the left and right bottom hinges are padded with too many gaskets.
• Reduce Gaskets: If you find that the left lower hinge has too many gaskets, causing the door to be too high, remove the left lower hinge using an electric screwdriver, and reduce the number of gaskets according to the door height.
• Reassemble: After adjusting the gaskets, reassemble the door by placing the hinge back into position and securing it with screws. Ensure that the door is properly aligned and the flatness deviation is less than 0.5mm.

3. Right Door Adjustment

• Inspect Hinges: If the right door is higher, follow a similar process as with the left door. Check the bottom hinges for excess gaskets.
• Reduce Gaskets: Remove the lower right hinge and reduce the gaskets as needed.
• Reassemble: Reassemble the door by inserting the hinge back and securing it. Again, check the alignment to ensure the flatness deviation is within the acceptable range.

4. Final Checks

After adjusting the door height, it’s important to check the overall alignment of the doors. Ensure that the doors close properly and that the flatness deviation remains less than 0.5mm. Additionally, check the door seals to ensure they are properly aligned and not separating from the seams.

By following these steps, you can ensure that the doors on the B422D appliance are properly aligned, which is essential for maintaining the efficiency and longevity of the unit.
