| 空调遥控器接收器故障 Air conditioning remote control receiver malfunction 故障现象：遥控不开机 Fault symptom: Remote control does not turn on 原因分析：检查遥控器，用遥控器对准普通收音机，按遥控器上的任何键，收音机均有反映，说明遥控器属正常，故障在室内机主控板或者遥控接收器。打开室内机外盖，检查220伏输入电源及12伏与5伏电压均正常，用手动启动空调，空调能正常启动运转。 Reason analysis: Check the remote control, align it with a regular radio, press any key on the remote control, and the radio will respond, indicating that the remote control is normal. The fault is in the indoor unit's main control board or remote receiver. Open the outdoor cover of the indoor unit, check that the 220V input power supply and 12V and 5V voltages are normal, and manually start the air conditioning. The air conditioning can start and operate normally. 说明主控板无问题，故障部位在遥控接收器元器件上，经检查，发现原因在于控制器接收回路上瓷片电容(103Z/50v)绝缘电阻偏小，只有几kΩ，质量好的瓷片电容应该在10000MΩ以上，漏电电流偏大而引起的遥控不接收。 It indicates that there is no problem with the main control board, and the fault is located on the remote control receiver components. After inspection, it was found that the reason is that the insulation resistance of the ceramic capacitor (103Z/50V) on the controller's receiving circuit is relatively small, only a few k Ω. The high-quality ceramic capacitor should be above 10000M Ω, and the leakage current is too high, causing the remote control not to receive. 解决措施：将103电容直接剪除或更换显示板后，空调器一直运转正常。 Solution: After directly cutting off or replacing the 103 capacitor on the display board, the air conditioner will continue to operate normally. 经验总结：造成不接收遥控信号的原因很多，除上述电容漏电外，无件虚焊也会造成不接收。 Summary of experience: There are many reasons why remote control signals are not received. In addition to the aforementioned capacitor leakage, faulty soldering without components can also cause non reception. 另外空调使用环境对遥控接收影响很大，当环境湿度高时，冷凝水在遥控显示板背部焊接点脚与脚凝结，线路板发霉，绝缘性能下降，焊点之间有漏电导致遥控不开机或遥控器失灵，清洁线路板，用吹风机干燥处理后，在遥控显示板背部焊接一层玻璃胶，遥控能够正常接收。 In addition, the environment in which air conditioning is used has a significant impact on remote control reception. When the environmental humidity is high, condensed water condenses between the welding points on the back of the remote control display board, causing mold on the circuit board, decreased insulation performance, and leakage between the welding points, causing the remote control to not turn on or the remote control to malfunction. Clean the circuit board, dry it with a hair dryer, and then weld a layer of glass adhesive on the back of the remote control display board to ensure normal reception of the remote control. 用收音机AM档可检测遥控器是否发射型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵信号，如手动开机后空调运行正常，可以排除主控板故障，由此可确定问题出在接收器，维修时不能简单地更换配件，尤其是短期内重复维修时，应仔细分析一下配件损坏原因。 Using the AM mode of the radio can detect whether the remote control is transmitting signals. If the air conditioning operates normally after manual power on, it can eliminate the fault of the main control board. This can determine that the problem lies in the receiver, and it is not possible to simply replace accessories during maintenance. Especially when repairing repeatedly in a short period of time, the cause of damage to the accessories should be carefully analyzed. |
