Power minutes or tens of minutes outside the machine automatically shut down time: Boot minutes or tens of minutes outside the machine automatically shut down, or outside the machine does not start changing the indoor pipe temperature sensor There is a plug-in to display fault after fault codes and run the code is not the same, Unplugged show the power or signal lines in general, motherboard problem. Running for some time displays general sensor problem. Weather turns hot, this air-conditioned and also come in great handy, however, air conditioning need to be careful of freon. They have been blown to pieces of the air conditioning unit, as well as the maintenance man was badly burned in Xuzhou brand central air conditioning prices, and the cause of the accident is caused by too much because the Freon added pressure, the air conditioning compressor explosion. Sheng Erda air conditioning maintenance: "The new Freon called '410A', so if you want to add refrigerant if air conditioning must be evacuated, if not evacuated, the air conditioning is great damage, easily blew up." Insiders told reporter, under normal circumstances, a qualified installation of air conditioning, in 3-5 years is no need to add freon, unless there is a refrigerant during use or transfer machine run drain phenomenon. But the real need for air conditioning freon people, Do not attempt to dismantle or add their own air conditioning, air conditioning manufacturers should try to choose the informal service sector and the designated qualified maintenance workers. Sheng Erda air conditioning maintenance: "We must be reminded that the refrigerant is not a plus, the better, but more so, it (cooling) effect is get out and normal, such as one of the (air conditioning) plus . 6 pressure Freon enough "poor reason Haier inverter air conditioner KFR-120LW / K2SDY heating effect analysis: on-site inspection of the air conditioning and heating can, but remote control can not control the wind speed, the outlet temperature reached 35 degrees, try to convert air-conditioning mode, the cooling wind speed can be high. Low adjustment of the central air conditioning, it is possible to determine the fan motor is good. You can doubt the indoor pipe temperature sensor is broken. Results: Replace the indoor pipe temperature sensor, the test machine is normal. Experience: temperature sensor plays a very important role in the air conditioning, it can cause a lot of bad fault, in this case, the air conditioning and heating, due to anti-cold wind function Xuzhou central air conditioning repair parts, the indoor temperature sensor feel 25 degree above the fan with low wind operation, reaching more than 30 degrees to set the wind speed run, more than find fault first wind speed is low, and the air temperature is high, it is necessary to check the fan is normal. When determining the normal fan, you can not doubt the temperature sensor check Xuzhou used central air conditioning recovery, causing the fan does not set the wind speed to the remote control operation, it is to replace the inner tube temperature sensor. In the fixed-frequency air in suspected bad sensor can be placed in a forced air-conditioning refrigeration state, such as air conditioners can be operated, and the current normal, generally considered bad sensor.
