Why is the Novoferm N-423 Garage Door Opener hand transmitter range insufficient?
- C
  Curtis EsparzaAug 19, 2025
  The insufficient range of the hand transmitter for your Novoferm Garage Door Opener could be due to a few reasons. The hand transmitter battery might be empty, so replacing it is a good first step. Alternatively, the antenna might be missing or misaligned; ensure it is properly plugged in and aligned. Lastly, there could be on-site shielding of the reception signal, in which case connecting an external antenna (available as an accessory) might help.
