Error code E15 on a General Super DC Inverter floor standing air conditioner usually indicates a communication error between the indoor and outdoor units.
Here are some steps you can try to resolve the error:
- Turn off the air conditioner and unplug it from the power source.
- Check the wiring connections between the indoor and outdoor units. Make sure all connections are secure and free from any damage or corrosion.
- Check for any loose or damaged wires or cables that may be causing the communication error. Repair or replace any damaged components as needed.
- If the problem persists, contact a qualified HVAC technician to diagnose and repair the issue.
It is important to not attempt any further troubleshooting or repairs unless you are trained and qualified to do so, as air conditioning units contain high voltage electrical components that can be dangerous to work with.
