When measuring the direct current voltage, turn the on-off switch to the category of the DCV (DC voltage) , pay attention to select a measurement range larger than the voltage to be measured, and confirm the polarity of the voltage to be measured.
AUX air conditioner service manual Chapter 7 Failure Analysis and Inspection of Electrical Control System Air conditioner can be controlled by both strong-current circuit control panel and weak-current electronic circuit control panel, control philosophies of which are different, so fault analysis procedures of the two types shall be described separately: Electrical system is the device to control and protect refrigerating system and fan system.
AUX air conditioner service manual (5)Heat pump air conditioner fails to heat If air conditioner can produce cooling air but fail to produce heating air, there must be some faults in magnetic reversing valve or switch. ① Magnetic loop of magnetic valve has burnt out or broken out because of: a、 Operate in severe environment; b、Magnetic loop stops and starts up frequently; c、 Operate under excessive voltage for a long time so that loops run under high temperature rise and insulation layer has been damaged.
AUX air conditioner service manual ② ③ ④ ⑤ ⑥ ⑦ ⑧ lower than rated value; Over-current on compressor: check if heat protector on the compressor pump shell has broken off. Normally, heat protector will break off if current is excessively large. Heat protector of three phase motor is embedded in motor winding in pump shell. Check junction box on the pump shell by using universal meter, both for single phase and three phase motor; if winding is current off, protector has cut off the power.
AUX air conditioner service manual three- phase. Single phase motor has two windings, i.e. startup winding and running winding. There’re 3 binding posts, in shell junction box of compressor. They are marked by A, B and C individually, representing running post, startup post and common post.
AUX air conditioner service manual winding touching shell can also occur in three phase motor. Check the faults with universal meter. For star- type connection motor, resistance can be measured individually; for triangle- type connection motor, three windings shall be disconnected before resistance values are measured. 4.

Remove diode from electrical panel, check its single phase conductivity with R×1K and R×100 of universal meter. Check method: contact two ends of diode with two handles of meter, record the resistance value, then change two handles with each other and measure again. For a normal diode, two resistance values are different greatly; large one is called reverse resistance and the smaller one forward resistance.
AUX air conditioner service manual noise can be heard.
AUX air conditioner service manual Reason Analysis: to check remote controller, point the remote controller to an ordinary radio and push any buttons on it, radio responded, so remote controller worked well, and there must be some faults in main control panel or receiver of remote controller of indoor unit.
AUX air conditioner service manual when indoor temperature sensor and heat exchanger exceed 25 Celsius degree, fan produces gentle wind; when temperature exceeds 38 Celsius Degree, fan produces wind of set velocity. We checked and found that wind velocity is very low, and wind temperature is quite high, so fan works well. So we presumed that the sensor failed to reflect the correct temperature, and then indoor fan can’t run at set velocity, so it must be replaced.
AUX air conditioner service manual the lamp was turned off, air conditioner functioned properly. When lamp was turned on, we checked receiver and found 2V AC electricity on the input end; when we turned out the lamp, and didn’t operate remote controller, there’s no voltage on receiver. Solution: replace fluorescent lamp with product of other brand Experience Conclusion: wave produced by electron rectifier fluorescent lamp may superpose on infrared wave and cause failure of receiver.
AUX air conditioner service manual on plastic panel may deform, so buttons may fail to work. In this case, control panel shall be replaced with same model product. Case 9 Compressor low -pressure can’t be started up Product Model：ASW-H12A4/HS Phenomena：Compressor of outdoor unit can’t be started up Cause Analysis: Indoor unit works well; voltage output and resistance of outdoor compressor are in normal scope, so there’s some problem in compressor.
AUX air conditioner service manual when we’re repairing air conditioners and avoid replicated work. Case 12 Transformer Failure Product Model：ASF-H18A4/FS Phenomena: air conditioner didn’t function after it was turned on Cause Analysis: checked power supply, there’s 220V input power, so power supply circuit has no problem. Checked power socket, resistance is infinite great, so fuse or transformer might burn out.
AUX air conditioner service manual Chapter 8 Troubleshooting guide for Refrigerating System Refrigerating system faults are very common to air conditioners; faults are various but they still have some rules and also many maintenance experiences for reference. Troubleshooting steps here for refrigerating system are not a must, but can be followed to eliminate faults. 1.
AUX air conditioner service manual there is some leak source, refrigerant will leak out and air conditioner can’t cooling proper or absolutely stop refrigerating. Leakage sources locate mainly on welds of evaporator, condenser, and capillary, return gas and discharge tube of compressor, flare mouth, copper nut, connection tubes and etc. Check the air conditioner visually and then inspect joints of tubes carefully. Generally, there’s grease spot on the leakage source.
AUX air conditioner service manual pressure hose with vacuum pump and vacuum the system. ②Tighten thimble head; Discharge air in the hose with refrigerant steam in system or refrigerant in the bottle. If small refrigerant bottle has been connected with hose and vacuum pumping has been done, there’s no need to discharge air. ③Start up air conditioner, check low pressure value when it runs stably and judge the remaining refrigerant in system.
AUX air conditioner service manual shall be no less than 10℃ and in heating operation, temperature difference shall be over 15℃; ⑤ High pressure: High pressure value of cooling operation shall be about 1.5~1.9MPa; ⑥ Weighing: When we fill the air conditioner with refrigerant, we shall weigh refrigerant with electronic weighing appliance if available. It is one best way to add the refrigerant.
AUX air conditioner service manual Pollution degree of refrigerating system can be classified as: slightly polluted and seriously polluted. When system is slightly polluted, condensed oil in it has not been polluted completely, and if refrigerant and lubricant is released from line of compressor, it is transparent and will become light yellow(normally they should be in white) if tested with litmus paper.
AUX air conditioner service manual Generally, system shall be purged under a pressure of 0.6MPa which can be pressurized with refrigerating compressor, nitrogen bottle or air compressor (compressed air can’t be used in Freon system). System shall be blown in sections, with dirt outlet set on the lowest point of each section. Each dirt outlet shall be plugged up with cork (tied with steel wire). When pressure reaches 0.
AUX air conditioner service manual ③、Weld high pressure tube first, and then the middle one of three low pressure tubes, finally left and right tubes; ④、Select proper welding machine, flame shall be adjusted and can weld the valve immediately. Pack the valve body with wet towel to avoid burning rubber and nylon sealing elements in it and causing the leakage of four-way valve. ⑤、；Weld the tube one by one and start welding the second one after the first one cools down.
AUX air conditioner service manual burned or components can’t start up. So clearance scope between pistol and cylinder is very small. For Diaφ50mm cylinder without pistol ring, fit clearance shall be within 0.011~0.018mm.
AUX air conditioner service manual Symptom is: when air conditioner is switched on, fuse protector breaks or air protector trips immediately. There’re three reasons for this symptom: a) Because motor stator windings have burn out, and insulation layer of electromagnetic loop has been broken and windings touch the motor shell and are short circuited.
AUX air conditioner service manual Cause Analysis: turned on the air conditioner, it could run normally. Checked filter of indoor unit and heat exchangers, and found that they were quite clean and wouldn’t impact the cooling efficiency. Checked capacitors and all parameters of indoor and outdoor fans, voltage was 220v, current was 13.5A, low pressure was 0.4MPa and there’s no extension line, outdoor compressor also run normally, in addition, no flow restriction was found.
AUX air conditioner service manual analyze this phenomenon, we shall check whether air flow of indoor unit is sufficient. If it is in normal condition, check whether there’s secondary flow restriction; judge the fault by analyze phenomena carefully.
AUX air conditioner service manual conditioner run 5 minutes, and evaporator of indoor unit was frosted, so we presumed that refrigerant was not sufficient; we checked and found that low pressure was 3KG. Turned off air conditioner, checked indoor & outdoor units and connection tube and found oil stain on the junction of low pressure copper tube.
AUX air conditioner service manual condenser, so refrigerant leaked out. Solution: repair-welded leak source and added refrigerant Experience Conclusion: when air conditioner is running, system pressure is zero, we can judge that refrigerant leaks out; generally, oil stain can be seen on leak sources. Maintenance personnel shall be familiar with blinking conditions of indicator.
AUX air conditioner service manual tubes, the one connecting discharge pipe of compressor was hot, and other three were also a little hot. Turned on the air conditioner in heating mode, heating efficiency was also unsatisfactory. So we were sure that four-way valve had some problems. Solution: replaced four-way valve, vacuum the system to check leakage sources and finally added refrigerant.
AUX air conditioner service manual Experience Conclusion: valve is too tight, so system is obstructed and then frosted. When refrigerating efficiency of new unit was unsatisfactory, do not add refrigerant without careful consideration. Case 15 Air conditioner was blocked by dirt Unit Model：ASW-H41A5/A Phenomena：Poor cooling efficiency, wind velocity didn’t change obviously Cause Analysis: totally 5 cabinet air conditioners were used in a workshop of a Garment Company, which occupied an area of 350m2.
AUX air conditioner service manual Phenomena：Refrigerating efficiency was unsatisfactory, outdoor unit stopped to run after it operated for some time. Cause Analysis: air conditioner was installed last year, and failed to run properly since then. Maintenance personnel checked the air conditioner many times, and had following data: running current was 12.5A, pressure was 5kg.f/com2, inlet wind temperature was 12 Celsius Degree, and outlet wind temperature was 30 Celsius Degree.
AUX air conditioner service manual Case 19 Water entered the system in installation Unit Model：ASW-H12A4/H Phenomena：Air conditioner could be turned on but couldn’t produce cool air Cause Analysis: run air conditioner for 10 minutes, it could cool normally, pressure and current was normal; air conditioner continued to run, low pressure decreased gradually, current also decreased, and cooling efficiency became unsatisfactory, so we presumed water entered system when air conditioner was installed.
AUX air conditioner service manual Chapter 9 Maintenance Cases of Noise and water leakage of AC Section one cases of air conditioner noise reduction Air conditioner noise is a common problem seen in our maintenance work, causes of which shall be paid attention to.
AUX air conditioner service manual presumed that fault was on bearing bush of left blade. Replaced bearing bush, noise could still be heard. Maintenance personnel checked wind blades and found that they’re installed left to the center and blade axis touched rubber seat of bearing and produced noise when running. Solution: move wind blade to right by 2mm and noise was eliminated.
