Samsung Electronics

Outdoor unit display

 (INVERTER1 PCB)

Judgment Method

∙  N-phase wiring error and EMI fuse short.

∙  DC-Link Overvoltage / Low voltage occurs.

Cause of problem

∙  Check the input wiring

∙  EMI fuse short circuit

Power off

Yes

Yes

220V is the voltage between terminal blocks L  

and N wire?

Check the voltage between L and N wire and 

then restart it

Replace inverter PCB and then restart it

Replace fuse, if the rectifier diode of the inverter 

PCB is normal.

No

No

Did EMI PCB fuse become short circuit?

1.  How to check
