Intercom repairs for no ring, no sound and one-way audio
Intercom faults can sit in the handset, entrance panel, amplifier, power supply or wiring. We narrow down the affected section before recommending parts.

No speech or one-way audio
Microphones, speakers, common audio wires and incorrect replacement handsets can all cause one-way or silent calls.
Intermittent faults
Loose terminals, ageing power supplies, movement at the door and water ingress can cause faults that disappear while being tested. Good symptom notes are useful.
Questions before you enquire
Common questions
Why did a replacement handset not work?
Door-entry handsets are not universally compatible. Terminal functions, call type and wiring must match the existing system.
Can you repair an old analogue intercom?
Often yes, depending on condition and parts availability. We compare repair cost with a sensible upgrade rather than automatically replacing it.
