1 品牌型號：春蘭空調KFR-120LW/S
2 空調現象：空調不制熱 空調內風機轉 空調外機整機不工作
3 故障部位：室內機電腦板 外機控制板 感溫探頭
4空調維修思路：此機是一浴室休息室使用，開機發現內風機轉，顯示屏工作正常且無故障代碼顯示，外機整機不工作，無法制熱。懷疑由于浴室里面溫度較高，會不會是溫度設置過低造成外機不工作，于是將溫度調至最高30度，外機還是不工作，拆開外機外殼，強行接通接觸器，發現壓縮機運行正常，管路壓力正常。懷疑還是內機控制板問題，本著先簡后難方法，先代換內機環溫傳感器，無效。再用一10K感溫探頭代換內機管溫傳感器，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
