Klimaire KSWG009H113 Split System Air...? system

The condenser pressure sensor may be at fault, also known as the cycling switch

Hi don the error code is a system overload. There are a lot of things that could be causing this temperature short circuit. Inwould take the cover of the unit and see if you can visually see any maybe dust or debri on any condenser coils or fans. If you can't figure it out call an expert.
Here is a link to the manual for your system

Check for correct voltage to unit short may have burned out breaker .

bad relay

I have a 3 unit split.
I found out that you can not have one unit set to warm and the other to cold. The compressor doesn't understand it.

Cycle off on and quickly re mode to Cool .
Do it to each unit and you will get it to stay on and then you can adjust.

Took a while for me but it did stay on after switching Mode at startup

did you open both service valves? If it's 89 degrees F in your home you are WAY under charged, assuming you are using r410. what is the pressure when the machine cuts off?

for this you have to go into the the board located in the right side of the unit if your problem is what i think it is crosswire on the board.

You need to either get the specifications from the fan manufacturer, or take air readings with a manometer or flow hood

There's probably crickets in it, someone may have forgotten to seal the refrigerant/drain line hole from the exterior of the home.

check your filters and coils for blockages , both these codes are pressure related , if the filter is blocked the system will not create the desired environment for the refrigerant to work properly as it is directly related to increasing and decreasing temperature .
