How to Solve the Abnormal Noise of Door Limiters?

[CodyLynn]

Here are the causes and solutions for abnormal noise in door limiters: 1. Issues with design and manufacturing processes, causing noise between the limiter arm surface and the roller bracket side. Severe misalignment between the door hinge axis and the limiter rotation axis. Recommendation/Measure: The door hinge axis and limiter rotation axis must be controlled within "s3", and the door hinges should be monitored. Solution: For design and manufacturing issues, seek replacement at a 4S shop. 2. Long-term violent opening or closing of the door, leading to deformation, bending, or damage of the door limiter due to excessive force. Solution: If the door limiter is deformed or damaged due to force, it needs to be replaced. 3. Wear of the door limiter during use or door sagging. Solution: Depending on the situation, replace the limiter if it is worn or its limiting function is reduced. 4. Lack of lubrication on the limiter surface. Solution: The simplest method is to use lubricants like grease for lubrication and rust prevention, reducing mechanical part friction and wear, and extending fatigue life.
