What to do if my Panasonic Other shows H11 error?
- AalishaguerreroAug 22, 2025
If your Panasonic Other displays an H11 error, it indicates an abnormal communication issue between the indoor and outdoor units. This could be due to: * A faulty indoor unit PCB, so you should check it. * A faulty outdoor unit PCB, which also needs checking. * Incorrect wiring between the units, requiring a wiring inspection. * Broken wires in the connections, so inspect them. * A disturbed power supply waveform, which needs to be checked.
