1 品牌型号：春兰空调KFR-120LW/S
2 空调现象：空调不制热 空调内风机转 空调外机整机不工作
3 故障部位：室内机电脑板 外机控制板 感温探头
4空调维修思路：此机是一浴室休息室使用，开机发现内风机转，显示屏工作正常且无故障代码显示，外机整机不工作，无法制热。怀疑由于浴室里面温度较高，会不会是温度设置过低造成外机不工作，于是将温度调至最高30度，外机还是不工作，拆开外机外壳，强行接通接触器，发现压缩机运行正常，管路压力正常。怀疑还是内机控制板问题，本着先简后难方法，先代换内机环温传感器，无效。再用一10K感温探头代换内机管温传感器，故障排除。

2 Failure phenomenon: the whole machine does not work when the internal fan is not heating
3 Fault location: indoor electromechanical brain board external machine control board temperature sensing probe
Maintenance ideas: This machine is a bathroom lounge use boot found in the fan display screen work normally and trouble-free code display outside the machine does not work no legal heat. Because of the high temperature in the bathroom the temperature will not be set too low so the temperature will be set to a maximum of 30 degrees the outside machine is still not working open the outside shell forced through the contactor found that the compressor is running normally pipe pressure is normal. Doubt or the problem of internal control board in line with the first simple and then difficult method the first replacement of internal ring temperature sensor invalid. Then replace the inner tube temperature sensor with a 10K temperature sensor troubleshooting.
5 Maintenance method: replacing the inner tube temperature sensor
