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 has beep Xuzhou hand air conditioning recovery, 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, capacitance negative or circuit board that line is very wide, and find other legs and feet easily oh] thermal protection repair the air conditioning and fluoride old! Today to an air conditioning and fluoride, air conditioning, a little old, about 2 o'clock in the afternoon. Plus a little bit. 0.3 gauge air conditioning, ammeter 3.8A. Then add a few moments, the gauge 0.4 meter beyond the rated current of 4A 4.2 meter nameplate off valve table, suddenly blooms 7.2A current Xuzhou second-hand air transfer, the next thermal protection. Then emptying the master table when the table is negative did not notice. Unscrew the screws fluoride tube, which may enter the air. Causing the ice block. Stopped two hours later, open air survey meter gauge 2.6A 0.3, then add a little bit to open the valve, pressure gauge 4.5 meter 4.2A dare added. Just above the three-way valve and a small amount of frosting finish. Should still have a little lack of fluoride, but the current is already high, what is the press is faulty, or capacitance effect declined? Or are there other reasons? (This machine is cold before the exchange, now replaced by cooling only, fan and compressor using a power cord) Sheng Erda air conditioning repair center to remind you: the transformation of central air-conditioning for two reasons Xuzhou, external electrical and mechanical wind capacity is insufficient , there is a problem with a compressor. Air conditioning in the running, the outlet air deflector how best location? Why? Cooling, wind deflector blowing up; when heating, the louvers downward blow. Because cold air is always part of the hot air is always part of the room, so that the cooling wind blowing in the room should be at; when heating should katabatic wind. So conducive to room temperature quickly and evenly.
