What does it mean when MSZ-GE09NA top light is blinking on and off? It works for about 2 minutes, then starts blinking. Have tried turning power off/waiting/ then power on the unit. Other inside unit works fine on same (heatpump) compressor.

The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!

In your out door unit you will have a dual capacitor. One side will be used to help start the outdoor fan and the other side is used to start the compressor. I have a fluke 187 volt ohm meter and can read uF. You probably have a bad capacitor. Its easy to change and by far the cheapest thing to do before calling a tech. It is out side where the electrical enters the outdoor unit. Be sure to kill all power to the outdoor unit and ground the capacitor before you remove and test. This has been the summer of capacitors here in SW Missouri. I have replaced several in the area.

There is either a problem with the outdoor unit fan or compressor or there is a communication problem between the two....
Did you check the number of blinks and then check the book to see what it means??...

SOURCE: Hey, i have a MSZ-GA80VA
Is there some error code.? Without knowing error code, chances for yor your problem is:
If indoor working properly, there is communication problem between indoor and out door. Check for power in out door after 3 minutes of a/c switched on. If no power problem with your PCB. Replace it.
