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

    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.

    Which systems show it

    • Daikin current US residential R-32 ductless single-zone systems, including AURORA R-32, ATMOSPHERA R-32, Entra R32, OTERRA R-32, and Nineteen-series style high-wall diagnostics where the same Daikin A/C/E/F/H/J/L/P/U code family is used.
    • Daikin concealed-duct/FDMQ indoor units where the Nineteen service manual explicitly lists the same indoor drain, fan PCB, remote-controller, and FDMQ-only C/U codes.
    • Daikin AURORA Multi R-32 and Standard Multi R-32 MXT/MXTH/MXM systems where the MXM engineering manual lists the same homeowner code table.
    • MXM/MXT/MXTH multi-zone systems for the additional multi-zone U-series and inverter/control codes specifically called out from the MXM manual.
