空调常见故障维修步骤/方法
Common maintenance steps/methods for air conditioning faults
*压缩机长时间运行而不能自停
*Compressor running for a long time without self stopping
故障原因1:制冷剂量不足，制冷剂全部或部分泄漏
Fault cause 1: Insufficient refrigeration dosage, resulting in complete or partial refrigerant leakage
排除方法:查出泄漏部位，补漏，将制冷系统重新抽真空，加入制冷剂等，应由专业人员维修
Troubleshooting method: Identify the leaking area, repair the leak, vacuum the refrigeration system again, add refrigerant, etc., and it should be repaired by professional personnel
故障原因2:过滤器堵塞
Fault reason 2: Filter blockage
排除方法:更换过滤器，制冷系统重新抽真空、加入制冷剂等，应由专业人员维修
Troubleshooting method: Replace the filter, vacuum the refrigeration system again, add refrigerant, etc., and it should be repaired by professional personnel
*压缩机不能运行
*The compressor cannot run
故障原因1:电源故障
Fault cause 1: Power failure
排除方法:用万用表、电笔遂项检查排除故障。保险丝坏则更换保险丝，电线断则更换电线
Troubleshooting method: Use a multimeter and an electric pen to check and troubleshoot the issue. If the fuse is broken, replace it; if the wire is broken, replace it
故障原因2:电源电压太低
Fault reason 2: The power supply voltage is too low
排除方法:用万用表测量电压值，必要时配用电源稳压装置
Troubleshooting method: Use a multimeter to measure the voltage value, and if necessary, use a power supply voltage regulator
故障原因3:电线连接松脱或断路
Fault cause 3: Loose or open wire connection
排除方法:检查电线连接部位，松脱的接插件应重新插牢、插紧，应由专业人员检修
Troubleshooting method: Check the connection parts of the wires. Loose connectors should be re inserted and tightened, and should be repaired by professional personnel
*风机不能运行
*The fan cannot operate
故障原因1:主控开关接触不良
Fault cause 1: Poor contact of the main control switch
排除方法:用万用表测量主控开关触点电阻，电阻太大或为零时，应作修复或更换处理
Troubleshooting method: Use a multimeter to measure the contact resistance of the main control switch. If the resistance is too high or zero, it should be repaired or replaced
故障原因2:风扇电机线圈损坏
Fault cause 2: Fan motor coil damaged
排除方法:用万用表检查，更换相同规格、相同转速的风扇电机
Troubleshooting method: Check with a multimeter and replace the fan motor with the same specification and speed
故障原因3:风机的电机与风叶间紧定螺钉松脱
Fault cause 3: The fastening screw between the motor of the fan and the fan blade is loose
排除方法:将紧定螺钉紧固
Troubleshooting method: Tighten the set screw tightly
故障原因4:风扇电容器断路或短路
Fault cause 4: Fan capacitor open circuit or short circuit
排除方法:检查电容器，更换相同规格的电容器
Troubleshooting method: Check the capacitor and replace it with a capacitor of the same specification
