Could have taken a severe power hit / surge ? Do the PC boards smell burned ?

Do you have a volt / ohm meter ? If so , check for good voltage coming into the indoor units . I think the power for the indoor units comes from the out door unit ? Check if the outdoor unit is providing power , at its terminal board . Look for fuses inside the out door unit .

Check the indoor unit fans for open and / or ground .

God bless
