What to do if Dorma Door Opening System doesn't respond but the green light is on?
- JJulie MontgomeryAug 1, 2025
If your Dorma Door Opening System isn't responding and the green LED light is on, it could be due to several reasons. First, check the program switch to ensure it's set to the desired function and not on [0] (OFF) or [II] (Permanent Open). If it's on Permanent Open, you can close it by double-clicking. Also, make sure the safety sensors aren't activated by any obstructions. If sensors are clear, inspect the sensor cable for damage and replace if necessary, including checking the jumpers. If no safety sensors are connected, ensure the terminals are bridged. In some cases, the operator itself might be defective and require replacement.
