If you can use the paper clip icon just above at the right end of the tool bar to send me a close up, well focused, well lit photo of the wiring diagram glued inside the blower door, I can mark it up with trouble shooting directions.
also check for 230v across all combinations of L1,L2 and L3 at the disconnect switch.
Tell me if anything else runs, and if any error code LED's are lit.
We can go from there.
Set the thermostat on cooling, and down to 60F, then I need you to jumper Red to G on the thermostat terminal... if the blower runs then its a thermostat problem.
Repeat the test but this time set the thermostat on FAN ON, and if the fan does not run, jumper Red to G and if the indoor blower runs, you have confirmed that its a thermostat problem.
With AC current in these situations a digital volt meter can give you a false voltage read (ghost read) due to feed back through the rest of the system...
(this is not true with DC circuits, this is a source of confusion for people used to trouble shooting DC systems such as with cars etc).
There is a 50/50 chance that you have actual 24vac power available at G and not just a ghost read... by doing the tests prescribed we can eliminate or confirm that. Without that jumper test, and the tests prescribed earlier we are guessing, especially with that particular wiring diagram.
I will opt out for now, so that other of our experts here can see your question...I will still be notified of your responses though, and will resume trouble shooting this with you if you like.
