Operating indicator light is flashing on Mr.Slim A/C
I had the same problem and I found it was that another unit had the heat running while I was trying to run AC on another (they're both attached to the same condenser) so it could only run heat or AC not both. Turn off the heat!
Mitsubishi split ac indoor light blinking unit not working
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.
Why does A/C display a blinking Eo code?
An EO error indicates an electronic error caused by either a control board problem or a problem with supply voltage to the heater. A single EO code is not cause for concern, but for repeated EO codes
