Objective By describing three failures and maintenance processes of Elekta Synergy linear accelerator, the ideas and methods of related problems were introduced, which could provide references for colleagues. Methods Some errors occurred,such as Low dose rate, Water temperature alarm and Touch guard interlock, based on the equipment failure phenomenon,software error messages, and combined with circuit diagram analysis, related faulty components were replaced. Results The system structure was well acquainted with, relevant experience was summarized, and the loss caused by equipment shutdown was avoided. Conclusion The linear accelerator system is complex and complicated with several failures. As long as the correct maintenance ideas are mastered and the failure reasons are analyzed, the maintenance technology can be improved, and the operating costs can be saved.
