Shenzhen Mitsubishi Air Conditioning Repairs Figure _ quote _ Fukuda air conditioning repair, air conditioning repair

Shenzhen home electrical maintenance services (www.jjdqwx.com) to build brands. Air conditioning stopped working, unable to refrigeration, this happens we tend to make a loss, in fact, according to the following way to detect faults: 1, the compressor drive belt is loose or broken; 2, fuse; 3, the fuse connecting wire; 4 connecting wire is disconnected; 5, compressor coupling coil and solenoid valve; 6, thermostat electrical contact is normal, the temperature sensing element is faulty; 7, the fan is normal; 8, ignition switches and relays; 9, compressor is frozen; 10, refrigerant lines for leaks; 11, compressor seal leaks. Failure to identify: 1, if there is hot water heater, evaporator heat release, the heater valve is not working. 2, when the engine is in any speed, with only minor changes table high and low readings, the tongue compressor valve failures. Air conditioning running noise Finally, Xiao Bian teach you how to generate noise when the air conditioning when the detector: 1, vent window blade is loose; 2, the compressor drive belt is loose, wear; 3, the compressor mounting bolt is loose; 4, Listen carefully to the compressor if there is noise; 5, the compressor wiring and solenoid valves. Failure to identify: 1, compressor coil and solenoid valve failure; 2, compressor level is too low; 3, the fan blower failure; 4, if too much moisture in the system, the expansion valve noise; 5, if high pressure is servo valve is closed, the compressor generates noise percussion. Winter air conditioning heating, air conditioning to control the sale and use of state general manager of home electrical maintenance services, Futian District, Shenzhen, Wang Junfeng said the air conditioner turned on, set the heat with the fastest speed of temperature control purposes, until the temperature is appropriate, change the low Wind energy and reduce noise. Air conditioning and heating to be stable, a slight adjustment to the heating temperature in order to ensure stability. Room with air conditioning and heating, minimize the number of windows and doors opening and closing, with thick quality, black-out curtains to reduce heat exchange inside and outside the room. Must avoid blocking the air conditioner outdoor unit air outlet, otherwise will reduce the heating effect; at the same time select a suitable wind angle, warm air is lighter than air, so the heating should put the wind angle to cut, heating efficiency will be greatly improved. Air conditioning noisy machine how to do? Noisy air conditioner machine mainly caused by two reasons, one is the system partly because the external causes; Analyzing method is very simple, if noise in cooling and heating operation state, the ventilation is normal, then the reason for the system failure If the fault is still noisy external causes in the ventilation state, repair method is as follows:? a, external causes big noise the machine (with different sound) - Fast judge ① inspection and servicing the machine if the filter is dirty block , cleaning. ② Check the indoor unit hanging board is securely attached? If not firmly re-fixed. ③ Check the fan motor is mounted securely? Are the cabinet if the resonance?, Can be adjusted. ④ Check whether the machine blade friction with the case? If you make adjustments. ⑤ Check whether the motor bearing abnormal sound? If so, replace the motor or bearings. ① Check whether the motor fan rock deformation caused by noise? If so, replace the blades. ② Check the indoor motor speed is out of control, too fast or jitter? If so, you should check the motor and the control circuit, a common motor capacitor fails to control the motor speed optical coupling thyristor breakdown, single conduction, etc., to identify the point of failure repair can. Second, the system causes abnormal sound, noise - in general there is a slight air sound analysis and repair system is working properly, is a normal phenomenon, if the airflow is large or sharp sound proof system is faulty, there are two common reasons : ① evaporator or connecting tube pressurized plaque off dead bend formed closure sound. Most of the machine moves, the installation process fails to cause operating procedures; the air conditioner after closing fluorine, the connection from the indoor to the outdoor unit's evaporator tube insulation pipe was called machine can find the point of failure, can be repaired. ② If the implementation of the above normal, the capillary assembly should be replaced.
