Samsung inverter not working

Hello all.

First post so please be gentle!!

We bought a house last year and in the living room is a Samsung Forte inverter a/c unit. This worked fine last year.
I tried to use it yesterday and whilst the indoor unit appeared to operate properly I could only get ambient air from it, no cooling or heating.
Since it was last used we have had a couple of power cuts and the supply has also been interrupted for other wOrk.
Searching online produced two different codes to reset the system and pair the units. I have tried both codes without success.
The indoor unit appears to function but nothing from the outdoor one, the fan never moves. The outdoor shows a red LED which, as far as I can tell, indicates a communication error with the indoor.
Both are Samsung units, indoor AQV12NSAN outdoor AQV12NSAX.
I don't have any manual for these.
Can someone help me please?

Thanks in anticipation

Here’s the manual for that unit.
Take the cover off the outdoor unit and read the code.

Hi Roughneck
thanks for the manual.
Read the codes and with a bit of checking looks like the PCB on the external unit is U/S.
Not a cheap fix. But at least I know.

According to what I have read on the internet mini's are very vulnerable to power surges and surge protectors are a must.

Also according to the net, a inverter mini is also more computer than AC so when not acting right a reboot is in order. With the unit on shut the breaker off to the unit for 20 seconds. Time off seems to vary by where it is posted, a minute must be more than enough.

Like Abe Lincoln tweeted, be leery of things read on the net.
