How to troubleshoot Panasonic KX-TD1232 extension that does not operate?
- SScott LaneSep 5, 2025
If a Panasonic PBX extension does not operate, there could be several reasons: * A bad printed circuit board (Extension Card): Exchange the printed circuit board for another one. * A bad connection between the system and extension: Plug the extension into the same extension port using a short telephone cord. If it doesn't work, repair the connection using a 2 wire cord. * A telephone with an A-A1 relay is connected: Set the A-A1 relay switch of the telephone to the "OUT" or "OFF" position. * A bad extension: Plug the extension into another working extension port. If it still doesn't work, replace the phone.
