Quick answer
Intercom faults usually trace to power (a failed supply or tripped breaker), damaged or corroded cable, a faulty door station from rain or tampering, wrong settings after a power cut, or a door release lock that has failed. One flat not working points to its indoor unit or cable; the whole building points to the entrance panel or power.

03Frequently asked questions
Why is my apartment intercom not ringing?
If only your flat is affected, the indoor station or its cable is the usual cause; if every flat is affected, check the entrance panel and power.
Can an old intercom be repaired?
Often yes, but when parts are unavailable an upgrade can cost less overall.
