The Daikin air conditioner has started shutting off frequently by itself. What should I do?

Frequent automatic shutdowns may be caused by:

Compressor overheating protection being triggered

Power supply issues (voltage drops)

System overload due to incorrect settings

Malfunctioning control board or sensors

What to do:

Check the voltage in your power supply (especially during hot weather)

Make sure the correct operating mode is selected and the compressor is not overheating

Check that the filters and outdoor unit are clean — an overheated unit shuts down for self-protection

Call a service technician to diagnose the electronics or compressor

Important: Frequent shutdowns can lead to device failure, so it’s best not to delay contacting service.
