FUJITSU ISN'T COOLING CORRECTLY - Fujitsu Heating & Cooling

Isn’t this wall mounted?

If you know the model, you can find the correct manual on their website

Check error code is correct as this extremely rare. Possible fan motor fault instead. If error code is correct, replace indoor controller pcb.

Most likely low on refrigerant. This will cause the evaporator to ice up which will then drip in side the room as the outer surface melts. It also causes less air flow through the heat exchanger which exacerbates the problem. You need to find the source of the leak which is probably at one of the flare joins. Unfortunately, I don't have a service manual for this model so cant tell you what the error code is. Consult a local tech.

what happens when you try to power it on? is the battery dead? i know that seems like a dumb question but it's possible that your charger may have gone bad and isn't supplying the correct voltage/amperage to the device to charge it

If the operation button is flashing 8 times, the timer light should also flash 4 times in each sequence. This indicates a failure of the PFC circuit in the outdoor unit which basically means a faulty outdoor board and will have to be replaced.
If the operation light is flashing 8 times by itself, the indoor controller board may have a fault. You can normally test this by putting the mode on the remote to 'Fan' and checking that the controls otherwise work normally - louvers work as directed and fan speed changes correctly when selected on the remote.
Most likely the fault lies in the outdoor board but you should contact a tech to diagnose correctly.

The left-most silver button by the power button is the wireless on/off key. The other two launch your default web browser and email client.
