How to Repair Intercoms | Troubleshooting steps
The majority of intercom issues are simple to resolve. In this case, you will require some essential knowledge and experience in order to repair them. If you live in an apartment, you must ensure that the intercom system is operational. Electrical tape, rubbing alcohol, a clean cloth, a volt meter, and a screwdriver are the tools needed to repair intercoms.
Step 1: Access the Buzzer
An intercom buzzer entry system is installed outside in place of a traditional doorbell. It is important to look at the buzzer of the intercom and assess it for any sign of general damage.
If there is general damage to the buzzer, you can simply opt for a buzzer replacement. If there is no visible damage, it shows the buzzer is still in great condition.
Step 2: Examine the Wiring of the Intercom
Gently Use a screwdriver to remove the intercom casing in order to assess the state of the wiring inside. Check the wiring and make sure that it has good contact with the button of your intercom.
If there is an accumulation of dust or dirt, use a clean cloth and rubbing alcohol to gently remove them. The accumulation of dust and dirt might prevent your intercom system from working perfectly.
Step 3: Test the voltage of your intercom system
Use a volt meter to test or view the voltage of the intercom. It might be a reason that it is not functioning properly. Now touch the wires together to see if you can hear the intercom buzzer noise when they make contact.
If there are no noise results, then the transformer is at fault.
Step 4: Inspect the wiring of the transformer
Inspect the low-voltage wiring connected to the transformer. If this has become loose, tighten it up using your screwdriver.
Step 5: Inspect the Buzzer Wiring
Inspect the intercom buzzer wiring. If you spot any loose wiring, use the screwdriver and electrical tape to tighten it up. Repair any damage to the surface of the wiring. Now use the volt meter again to test the voltage. Your intercom will have a voltage reading of between 6 and 16 volts if it is working correctly.
