I have the same problem too. Aircon cannot switch on, two lights from the top is blinking. Everytime I turn on, the flip is open then close again with sound. The technician said the thermostat cable need to be replace. It cost about $15. The cable is 14" long. Hope this help.

Green blinks indicate communication to outdoor, but red light indicates communication problem. Check PCB.

The blinking is an indicator that it needs service. Call a technician! Ask if they are experienced in mini split systems. You can check the air filters. Check the outdoor coil to see if its clean or covered up with dirt. And at the breaker or disconnect, turn off power, wait 5 mins, and turn it back on. Then give it 3-5 mins to see if it will reset itself. If this don't work, call a tech/service provider! These units are troublesome to troubleshoot.
