This tool collects common fault codes for air conditioners from 38 major brands—including Gree, Midea, Haier, Aux, Daikin, Mitsubishi, Hitachi, Hisense, and TCL (378 codes indexed so far)—and supports searching by brand, fault code, or keyword to quickly view the code meaning and handling suggestions. The database is continuously expanded.
Usage tip: first select a brand, then enter the fault code (e.g., E1, P0, F4) or a keyword (e.g., “communication”, “sensor”, “high pressure”, “refrigerant leak”) to query.
Disclaimer: fault codes may differ across brands, series, and model years; please refer to the official service manual of the corresponding brand. Operations involving refrigerant, electricity, or disassembly carry safety risks—contact a qualified technician. Results from this tool are for reference only.
