What does error H23 mean on my Panasonic CS-S9NKR Air Conditioner?
- KKarina BellSep 12, 2025Error H23 on your Panasonic Air Conditioner indicates an abnormality with the indoor pipe temperature sensor. This can be due to: * A faulty connector connection, so inspect and repair the connector. * A faulty sensor, so replace the indoor pipe temperature sensor. * A faulty PCB, so check and replace the PCB if defective.
