Outdoor Unit Recall: 11-time blink - Compressor synchronous abnormality

What does 11-time blink (recall mode) mean?

When the outdoor unit failure mode recall function is active, the indoor unit's upper lamp blinks eleven times, then stays OFF for 2.5 seconds. This indicates a compressor start-up failure protection has activated due to a distorted waveform of the compressor current.

• Loose or incorrect compressor connector
• Issue with the inverter or compressor
