Thanks every one for all useful recommendations. These hinges are old and can’t do up/down adjustments.
Looking inside out, the right side door is perfect after seal changes and adjusting the hinges. I turned the top inward, the bottom outward and the middle neutral. This helped. I did the reverse on the left. This doesn’t help much.
After locking the left door only, there are still gaps on both sides as the top door pushes a few mm outward.
However, the seal and the adjustment on the right are so good now, locking the door shut fully gets a perfect seal.
Will continue the trial and error for the left door. Thx
