空調故障日期：2022年3月24日

      品牌型號：大金空調KFR-35GW交流變頻

　　故障現象：空調制熱啟動后幾分鐘即停，面板綠燈閃 外機不開機

　　故障部位：電控系統

　　空調維修思路：

　　1、電壓220v正常

　　2、查故障代碼，是空調內外機通訊故障，檢查線路連接良好，強行制冷正常。手握室外冷凝器傳感器可以啟動制熱。

　　3、打開空調外機，測傳感器阻值偏大，更換阻值小的傳感器15K 20K(25度時)均正常運行。

　　維修方法：更換傳感器試機正常。

英文注釋：

Brand Model: Daikin KFR-35GW AC Converter

Failure phenomenon: air conditioning heating start a few minutes after the stop green light outside flash panel does not start.

Fault Location: Electronic Control System

Maintenance thoughts:

1、 Voltage 220 V normal

2、 Check the failure code which refers to the communication failure of the internal and external machines check that the lines are well connected and forced refrigeration is normal. Hand held outdoor condenser sensor can start heating.

3、 Turn on the external machine and the sensors with large resistance value and small replacement resistance value are in normal operation at 15K 20K (25 degrees).

Maintenance method: replace sensor test machine normal.
