Questions before you enquire

Common questions

Can the fault finder diagnose the system?

No. It highlights likely fault areas and the information useful for triage. Electrical testing is normally required for a confirmed diagnosis.

What photographs should I take?

Photograph the handset, entrance panel, door lock or maglock, any controller or power supply you can safely see, and any model labels. Do not remove covers.
