Sanyo air error codes

The last generation Sanyo air conditioners possess efficient self-reliant diagnostics of hitches. Having detected any malfunction in operation, the system stops the operation of an air conditioner and immediately notifies of the error. The system of codes representing a blink of light indicators in specified order is developed for an alert. The indicators with error codes are located on the face of an internal module, as well as on the external module. Our table below will help to decipher error codes.
