What should I do if my Panasonic Air Conditioner displays H33 error?
- XxbuckleySep 8, 2025
The H33 error on your Panasonic Air Conditioner indicates an unspecified voltage issue between the indoor and outdoor units. This can be caused by: * Wrong models interconnected, so ensure compatible units are connected. * Wrong indoor and outdoor unit PCBs used, so check and replace incorrect PCBs. * A defective indoor or outdoor unit PCB, so test and replace defective PCBs.
