Detailed Product Description: | Changhong KFR-25GW / H air conditioning on power no reaction (1) to observe indoor light does not work, use a multimeter to check the power outlet has 220V, the power supply is 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 replaced with new central air conditioning immediately, should identify the reasons 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. Gree air-conditioning cooling effect is not a small one a small one, Gree air-conditioning cooling effect is not good, I could not find the reason, not lack of freon, fan is running, drainage normal, normal operation of the compressor. Xuzhou machine also cleaned central air conditioning installation, air outlet temperature of 20 degrees, the remote control or how to adjust the outlet temperature of 20 degrees, the other can not find the problem in the air conditioning repair special attention to the temperature and humidity. Do you want these days almost everywhere inside the country and stuffy hottest days of the year, normally air conditioning usage is not so high, but now almost no one will feel bad money without a few open air central air conditioning, cleaning and maintenance of Xuzhou This has almost no power will be few places so good, especially second and third regions, not to speak of it. Large air-conditioned room is small so it is almost everywhere, while the former may also be a little better these days certainly does not. Think about it; air conditioning cooling heat greater than room temperature will drop, until the heat absorption refrigeration equal amount of time in Xuzhou Hitachi central air conditioning sales, the room temperature will not fall, if the heat absorbed is greater than the cooling capacity, then the cooling effect is obvious not as good as gone ...... Common symptoms of central air conditioning (1), drain: refers to refrigerant leakage; electrical (wiring, body) leakage and other damage caused by the insulation. (2), block: refers to fouling and plugging the ice refrigeration system; air filter is clogged; air inlet and outlet are an obstacle blockage. (3) off: an electrical line break; fuse blown; due to overheating or excessive current overload caused by the contact is open; the cooling system pressure caused by abnormal pressure switch contact is opened and the like. (4), burn: refers to the compressor motor windings, fan motor windings, solenoid coils, relay coils and contacts, etc. are burned. (5), the card: a compressor means jammed, jammed fan, moving parts of bearings jam. (6) damage: broken finger compressor valves, piston scuffing, fan blade fracture and various parts breakage. Central air conditioning, refrigeration Sheng Erda, central air conditioning installation is provided by Xuzhou Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou 圣尔达 Refrigeration Electrical Services Limited (xzktw.com) strong, credible, Xuzhou in Jiangsu Province of heat, refrigeration and air conditioning equipment industry has accumulated a large number of loyal customers.
