What it means
Daikin controls can wait about 3 minutes before restarting the compressor after a stop, mode change, or power interruption. That delay protects the compressor and is not a malfunction.
Urgency
Not an error
This is a normal status indication, not an error, unless comfort is poor, water is present, or the indication never clears.
Likely causes
- Brief power event, brownout, or unstable supply voltage
- Loose power connection, reactor, or outdoor electrical component problem
- Inverter/IPM protection or current-detection fault
- Compressor winding, drive, or outdoor board fault after power checks pass
Homeowner fix
Wait several minutes without repeatedly pressing buttons or cycling the breaker. Operation should resume when the protection timer finishes.
When to call a pro
Call for service if the unit never restarts after the wait, a breaker trips, or an error code appears after standby.
Repair vs replace
This is a normal operating status, not a repair-or-replace decision.
