Features: With the improvement of people's living standards and the maturation of air conditioning technology, air conditioners have entered the homes of the general public. Due to the development of air conditioners, various models of fixed-speed and inverter air conditioners from different brands have been continuously introduced. At the same time, the development and application of microprocessor control technology have continuously improved the quality and functions of air conditioner products, which has accordingly made it difficult for some maintenance personnel to handle certain issues. For this reason, the authors, starting from practicality and combining years of maintenance experience, have compiled the "Comprehensive Self-Diagnosis Codes for New Air Conditioners" based on the various display contents of air conditioners and referencing relevant maintenance materials. The content includes self-diagnosis codes for household, commercial, and office air conditioners, providing great convenience for air conditioner maintenance. The book is divided into two parts. The first part presents the fault display contents (codes) of air conditioners (LCD displays, indoor unit indicator lights, outdoor unit indicator lights) and the actual fault locations during maintenance, with examples from more than 30 brands such as Aucma, Changhong, Chunlan, Daikin, Dalian, Toshiba, Galan, Gree, Haier, Hisense, Hobaco, Huake, Huikang, Kelon, Leihua, Midea, Mengpai, Ningbo, Hitachi, Mitsubishi, Sanring, Sanyo, Shuanglu, Panasonic, Sharp, Xiaotian, Xiaoya, Xinfei, Xinke, Electrolux, and Zhishan, providing various inspection methods for air conditioners. Maintenance personnel only need to refer to the fault codes provided in the book to locate the fault points and promptly resolve the issues. The second part includes the technical parameters of various components of air conditioners. This part mainly covers the technical parameters of compressors, refrigerants, refrigerating oils, evaporators, insulation materials, and more.
