How to fix Nabco Door Opening System when the drive unit fails to react?
- DDr. Taylor Sparks DVMAug 13, 2025
If the Nabco Door Opening System drive unit isn't reacting, with no automatic opening or activation from sensors or buttons, the issue might be a missing power supply voltage. First, switch on the main installation switch in the side cover. Then, measure the mains supply voltage and check its cabling, fixing any problems found. If these steps don't work, the control unit may need to be replaced.
