Services: 1, 2 air conditioning installation, air conditioning maintenance 3, 4 wedding dresses, air conditioning plus liquid 5, air disinfection 6, 7 air conditioning maintenance, air conditioning replacement bracket 8, air conditioning recovery service process: the user dial the hotline repair - customer service staff and technical staff met - user tells Address Tel Symptom air conditioner models - Appointment - send a single 1-2 hour fast door (check in after endlessly offer maintenance charge) compressor common failure is not running and no major Xuzhou sounds conditioning maintenance, there is no running sounds, noise, small displacement (1), is not running and no buzzing sounds of the cause of the failure is caused by internal motor windings open, measured by a multimeter power block housing between terminals overcast value to determine if the resistance is infinite or too large, indicating winding open (2), not running but buzzing bass sounds caused mainly due to the failure of the motor winding short circuit or mechanical systems appear Card cylinders, not only when the axle failure, winding short buzzing sounds, and the shell temperature of the compressor is high in a short time, it will not cause overload Xuzhou Hitachi air conditioning repair action for this failure, with a multimeter electricity the resistance measured between the terminal block, and if the resistance is lower than the resistance of the resistance across the CR is less than the normal or CS ends at both ends of the resistance RS, described within the compressor motor winding short circuit, and measuring the compressor current will be greater than normal, while the mechanical system in the card cylinder, when axle failure, the motor winding resistance is normal. LG air-conditioning, some compressors built-in thermal protection, when the compressor overheating, over-temperature protection device is turned off, then if the measure resistance between the compressor is infinite, so the air conditioning maintenance and fluoride Xuzhou, measuring motor windings When the temperature of the resistance to be immediately dropped to the ambient temperature in Asia after the same, otherwise beginners may misjudge the compressor motor windings open. Methods and techniques of suspected card when the compressor cylinder, direct tapping with a hammer after the shutdown of the compressor housing, electricity and air conditioners for the United States, if the compressor is able to operate normally, indicating that the card cylinder troubleshooting, adding some frozen lubricants can continue to use, if percussion invalid, the first compressor lubricant filling some frozen, and then test to see whether the operation, if the operation, indicating a fault caused due to lack of refrigeration lubricants, if still can not run, you need to replace the compressor.
