Say whether the wall control or another handset still works normally. That comparison helps frame the control issue without proving which part is faulty. Keep the model information available if it can be read safely.
Should a warning be cleared before the visit?
Preserve the observed pattern and explain when it appeared. A general memory wipe can remove working accessories while leaving the original fault unchanged. Any reset should follow the correct model guidance.
Can a connected replacement reuse my controls?
Accessory compatibility depends on the selected equipment. Ask which remotes, keypad and fixed controls remain usable before choosing a replacement because it offers an app or other connected feature.
Why is a sensor bypass inappropriate?
The photo-eyes form part of the closing protection. Defeating them does not correct an alignment, wiring or obstruction problem and can remove a safeguard. Explain an unsecured opening by phone instead.
When should a physical door problem take priority?
Report a tilted section, hanging hardware or a loose lifting cable before concentrating on connectivity. Those conditions affect whether the assembly should move at all and need assessment before ordinary operator troubleshooting.
