2-time blink 2.5 seconds OFF — Outdoor unit overcurrent protection repeated

What does 2-time blink 2.5 seconds OFF mean?

The outdoor unit LED blinks 2 times with a 2.5-second pause. The unit stops and restarts 3 minutes later, repeatedly, due to overcurrent protection (large current flowing into the power module).

• Large current flowing into the power module (IC700)
• Compressor connection issue
• Stop valve closed
