Kanion air conditioners come with a self- diagnosis system. This basically means that the air conditioner determines most the troubles on its own and provides an error code on the LCD screen, then based on information from the user’s manual, it is easier and faster for the user to follow the steps and solve the trouble at home. Furthermore our local representatives are always available to assist with troubleshooting. Additionally, Kanion Service and Support Department provides assistance for any issue, customers may get in contact with Kanion Service & Support Department at kanion@kanionco.com or through https://www.kanionco.com/contactus.
