When this code appears—often through a pattern where the "Super Quiet" LED stays lit while the "Operation" and "Timer" lights blink—it signifies that the control boards (PCBs) are unable to synchronize. This typically occurs because the installed circuits belong to different models, even if they appear physically identical. Primary Causes of Error Code 9c
The O General AC Error Code 9C is a specific error indicating a problem with the indoor unit's memory chip (EEPROM). While a simple can often fix a temporary glitch, a recurring 9C error usually signifies a need to replace the indoor printed circuit board (PCB) .
If your hard reset does not resolve the issue, contact an authorized service center or search for professional assistance through the O General Global Support Portal to arrange for a technician to evaluate your outdoor PCB.
Check for Loose WiresIf you are comfortable opening the service panel (and the power is disconnected), check the plugs connecting the fan motor to the control board. Ensure they are seated firmly and show no signs of burning.

I often get e-mails from people asking how they can donate to my projects, but I don't like to accept donations for this particular kind of stuff. If you'd still really like to help out, though, if you buy any EarthBound/MOTHER merchandise through these links, I'll get a dollar or so. This will help keep EarthBound Central up and running, not to mention many of my other projects, like Game Swag!
