The alarm light of the housekeeper's electricity meter is on.

If the alarm light of the charterer's electricity meter is on, it may be the following reasons: 1. Electricity meter failure: the electricity meter itself is faulty, so it is necessary to contact the power supply department to repair or replace the electricity meter. 2. Overload: The electrical load connected to the instrument is too large, which exceeds the rated power of the instrument. It is suggested to reduce electricity consumption or increase the capacity of electric meter. 3. Short circuit: The wire is short-circuited or has poor contact, so it needs to be checked and repaired in time. 4. Aging of household appliances: Aging of household appliances may lead to unstable electricity consumption and need to be replaced or repaired in time. The charterer can check the condition of electrical equipment at home first, or contact the power supply department for maintenance.
