Is the board actually the problem?
Control boards are the most over-diagnosed part on any telephone entry system. Work through this before ordering — several of these faults look identical from the outside and cost a fraction of a board.
| Symptom | Likely cause |
|---|---|
| Display dead, no backlight | Power first, then the board |
| System will not dial out | The line or the cellular/VoIP device before the board |
| Dials but no audio either way | The voice circuit on the board |
| Keypad unresponsive | Keypad or the board |
| Programming will not save | Memory or the board |
| Gate relay never fires | The relay side of the board, or the wiring to the operator |
| Erratic behaviour after a storm | Surge damage — a very common cause on entrance equipment |
Order by the number printed on the board, not by the model on the machine. Boards changed several times within the same model run, so two units with identical model numbers on the data plate can take different boards. Open the control box and read the number off the board itself.
Common questions
Will this fit my unit? Check the number printed on your existing board against the part number above. If it matches, or matches one of the alternate numbers listed, it fits. If you cannot read it, send us a photo.
Will I lose my programming? Yes. A new board arrives empty — resident directory, entry codes and settings all need re-entering. Export or write down your programming before you start if the old board still powers up.
Is this genuine? Yes, genuine OEM. Aftermarket boards exist for some models but firmware behaviour varies, and a control board is not the place to economise.
Can I fit it myself? Physically it is a few connectors and standoffs. The commissioning afterwards — limits, force, safety devices — is what needs care, and on a commercial or multi-family installation it needs to be done to UL325.
