Glass panel visibly misaligned or tilted in the door frame
Grinding, scraping, or squealing noise during door operation

How to Fix It
Solution Steps
1Check for debris or obstructions in the sensor beam path and clean sensor lenses with a soft cloth
2Inspect the bottom guide channel for debris, damage, or misalignment and clear any obstructions
3Examine the header rail and roller carriages for wear — replace rollers if flat spots or cracks are visible
4If the glass panel is misaligned, a technician will re-seat the panel in the carriage and adjust guide shoes
5For control board failures, a certified automatic door technician will diagnose and replace the controller
When to Call a Professional
When the door will not close and the building entrance cannot be secured overnight
When the glass panel is visibly tilted or at risk of falling from the carriage

Stay Ahead
