Panasonic Aircon Blinking Light Patterns
Use this Panasonic blink table to match patterns and narrow next checks before booking.
Before you use this tool
This is a blink-pattern guidance table, not a model-exact diagnosis. Pattern meaning can vary by controller and series. If your controller shows a direct code (for example `CH21`, `U4`, `E6`), use the error-code guide for a faster match.
Safety warning
Stop using the unit and contact a technician if the breaker trips repeatedly, you smell burning, see sparks, hear loud electrical buzzing, or water is leaking from places it normally should not.
