Detailed Product Description: | Compressor common fault is mainly used does not run air conditioning and no barking, no operation has sounds, noise, small displacement (1), is not running and no buzzing sounds of the cause of the failure is caused by an internal motor windings Open Xuzhou hand air conditioning installation, by blocking between the measured values ??of the shell with a multimeter electrical terminals female judge, if the resistance is infinite or too large, indicating winding open (2), not running but buzzing bass sounds cause of the failure The main reason is that the motor winding short circuit or mechanical systems appear card cylinder, not only buzzing sounds when the axle failure, winding short-circuit, and the shell temperature of the compressor is high in a short time, it will not cause overload action for this failure Xuzhou hand air conditioning maintenance, power block with a multimeter measure the resistance between terminals, if resistance is lower than the resistance of the resistance and CR CS ends at both ends of the normal or less than the resistance across RS Xuzhou hand air conditioning hire, indicating a short circuit in the compressor motor winding and measuring the compressor currents 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 when you want to measure the motor winding resistance Then the temperature dropped to sub-ambient temperature 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. Hisense KFR-3601GW air conditioning units turn the outdoor unit does not start the focus should be checked: 1, the flow through the outdoor unit 300V power supply is normal; 2, with a multimeter to test the power module switch, if there is a short circuit or open circuit breakdown phenomenon does not work ; 3, whether to issue the compressor start "buzzing" sound, or a larger shock; 4, the DC voltage detection circuit is normal. The figure is the Hisense KFR-3601GW inverter outdoor unit control circuit power supply circuit diagram. Fault detection: Check the outdoor unit control circuit switching power supply output section, each group found no voltage output: measured switch collector and emitter voltage of 300V, work properly; remove the switch, use a multimeter to "diode" test Most stalls measured and found open between b, e pole (emitter), concluded that the switch is damaged. Replacement of the same type switch, power test machine, troubleshooting. The air conditioner is inverter-type air conditioners, indoor and outdoor unit has a control circuit. In this case the outdoor unit is not working properly, mostly outside the control circuit, the DC power supply or inverter power module failure transfer _ Sheng Erda Xuzhou hand air conditioning refrigeration (certified) _ Used air conditioning provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) 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. Sheng Erda leader in refrigeration staff warmly welcome all inquiries negotiations to create a better future Sheng Erda refrigeration. |
