Novoferm garage door opener operates from wall button but not from any remote controls (no display error).

Safety first: Keep clear of the door while testing remote operation.

Steps to try:

• Verify remote type: Ensure your Novoferm hand transmitters match the opener's radio system (frequency and coding). Mixing systems will not work.
• Reprogram remotes: Enter the receiver's learn mode (press the learn button until LED flashes) and press the remote button until the LED confirms pairing.
• Check antenna: Inspect and straighten the antenna wire. Do not cut it shorter.
• Check settings: Some models allow disabling radio control via menu or DIP switch. Confirm that radio is enabled.
