Detailed Product Description: | Air conditioning air conditioning repair method does not boot does not start, do not start there are two kinds, the first is the power no response, [transformers, fuse, rectifier bridge] these things should be a pediatrician, and other important measurement 5V voltage is normal Most of such problems in the CPU for Crystal [next] can be resolved. There is also a plug-in buzzer sound, remote control can not boot [manual] basically is the first to receive bad LF receiver will not know, under the online search to find receiver board foot is easy, right, negative capacitance or board very wide that line, find other legs and feet easily oh] Changhong KFR-25GW / H air conditioning on power no reaction (1) to observe the work of the indoor unit light is not on, use a multimeter to check the power outlet 220V Power normal. (2) Remove the indoor unit casing, fuse Check the indoor unit on the PCB, and found the fuse has blown. In this case the insurance can not be immediately replaced with new reasons should be identified in order to be replaced. (3) further measurements with a multimeter ohm power transformer primary resistance, measured as 0Ω, blown fuse caused due to a short circuit. (4) carefully observe the transformer did not find traces of burnt, so suspect varistor damage, remove the varistors with a multimeter ohm measurement, cue really short-circuited. (5) Insurance tube put on the same model with the same parameters of varistors, the air conditioner is working properly. If not the same type varistor on hand, emergency method is temporarily not Varistor power test machine. Common failure analysis split type air conditioner air conditioner refrigerant compressor starts running 3 minutes after the outdoor unit external valve, liquid pipe condensation phenomenon, then run 10 minutes later, the trachea, the valve also appeared condensation, indicating air conditioning refrigeration operating normally Xuzhou transformation of central air conditioning, ample refrigeration system refrigerant. If you start the air conditioner refrigerant compressor, hydraulic valves, hydraulic tube a frost phenomenon began with air conditioning, a few minutes later, the frost has melted into a gel, run 15 minutes later, the trachea, the valve condensation phenomenon, indicating that the air conditioner cooling System slight deficit fluorine, but also basic enough, generally do not need supplements refrigerant. If you start running after the air conditioner refrigerant compressor Xuzhou air conditioning maintenance and installation, valve, liquid pipe frosting appears, over 15 minutes after the pipe, the valve also appeared frosting, indicating sufficient refrigerant in the cooling system, the indoor unit air filter is dirty, due to poor heat exchange effect. If after starting the air conditioner refrigerant compressor after running Xuzhou hand air conditioning recovery, beginning valve, liquid line appears frosting, frost after a few minutes, not only is not based, but the thicker end, running ten minutes, the trachea, the valve still no dew or frost phenomenon, indicating the refrigerant within the refrigeration system has a serious leak, the need for up-fluoro-operation. If the air conditioner refrigerant compressor start after running for some time, still no valve, liquid pipe condensation or frost, indicating the refrigerant within the refrigeration system leaks have all finished, the need for refrigeration system thoroughly serious leak, remove the drain After the point, and then refilling the refrigerant. When the air conditioner for cooling operation, when the refrigerant compressor starts to run 15 minutes, I'm airflow temperature should reach more than 8 degrees; 15 minutes after the compressor is running in winter heating, the import and export of gas flow temperature should reach 14 degrees, Description good heating and cooling effect of the air conditioner. Xuzhou hand air conditioning recovery, Sheng Erda refrigeration (certified), air conditioning is provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) is in Xuzhou, Jiangsu, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. In Sheng Erda refrigeration leadership with the staff warmly welcome all inquiries negotiations to create a better future for refrigeration Sheng Erda. |
