My doorbell is broken. Does it cost money to repair it?

It's free, but it was repaired by the manufacturer of the door. At that time, when I bought the door, the maintenance fund had been paid enough. It is estimated that in the past 20 years, owners have usually paid for the security doors and intercom systems themselves. My aunt's house has been repaired for more than ten years. Provisions do not need to pay property maintenance fees, paid from the maintenance fund.
