My carrier breezo inverter ac is showing bl on led, although its filters have been cleaned 5 days ago by carrier technicians.

If your Kenwood 1 ton inverter AC is having trouble starting and sometimes shows the compressor symbol before turning off, there may be a few things you can check to diagnose the issue.

1. Power Supply: Check that the AC is receiving proper power supply, and the circuit breaker is not tripped. Sometimes, due to voltage fluctuation, the compressor may not start.
2. Dirty Air Filters: Check the air filters and clean them if they are dirty. Dirty air filters can reduce the airflow and cause the AC to malfunction.
3. Faulty Thermostat: If the thermostat is faulty, it may not be able to detect the temperature properly and cause the compressor to not start. You can check this by setting the temperature to a lower level and see if the AC starts.
4. Low Refrigerant Level: Check the refrigerant level in the AC. Low refrigerant levels can cause the compressor to not start.

If none of these steps solve the issue, it may be best to contact a professional AC technician to diagnose and repair the issue.
