Look on the back of your furnace door, maybe the fault codes are listed there.

The owners mannual does not get that involved, outside unit is not running.removed the cover on the outside unit did not see anything obviosly wrong, checked power to the unit it is there.

try googleing i was able to come up with the install guide which of course isnt helpful although it does describe putting it in a test mode i have installed alot of these ductless splits but mostly fujitsu and never really had problems with them so other than a little internet sluthing im no help

The troubleshooting guide tells me that the circuit board in the wall unit is bad.Trying to find the circuit board on line not having no luck
