Check reactor located in control plate. If reactor is normal,
exchange INVERTER PBA.
Check Input current sensor on Inverter PCB
Check INVERTER PBA's temperature. Power off and cool
down INVERTER PBA, and then restart the outdoor unit.
Check the coolant charging status
Check the indoor EVA sensor
Check if the outdoor unit service value is open
Check that the indoor/outdoor installation pipe/wiring
are correct
Check the option code of the Control Kit
Option setting data is wrong.
(This error don't occur in EMF 150-AM).
Check EEPROM DATA.
Check the normal operation of PCB.
