Door is not tight
1,Door seal corners is turned up slightly
Check if there is a gap between the door seal and cabinet
Common method :place one coin between the door seal and the cabinet,if the coin does not slide down, the door seal can be deemed as normal.
But If there is a gap between the door seals and cabinet,please call a service.
Note:Attractive force of door seal is generated by the magnetic bars inside seals and the cabinet. However, the magnetic bars inside the seals are not integrated along the four sides, especially at the joints. The joints are welded together and there is no magnetic bar inside the welded corners. So maybe the corners is turned up slightly, it does not affect the sealing performance.Please don't worry about it.
2,Door seals have smaller magnetic.
If the door seal's attractive force is increase, the pull force of opening door will increase too .It may cause the door seal deform easily and it will shorten the seals'using life.
So in production we adjust the door seal's attractive force reasonably while ensuring their tightness.
