Does the property charge the owner to repair the doorbell?

As a routine property service, the owner should maintain his own parts, and if there is property maintenance, there is a charge. Property services * * * with areas * * with facilities.

If the property serves the interests of the people, it may be free of charge. If materials are needed, the owner will pay for them.

It shouldn't matter to ask an acquaintance of the property for help. Don't complain if it can't be repaired.

Normal doorbell can be used for several years, and a battery can be changed at most. Check the electronic components for poor contact or disconnection.

I hope to give you a reference.
