What are the reasons that air conditioners do not cool after a long time?
1. Check whether the air conditioner is working properly, including the indoor unit and outdoor unit, especially the outdoor compressor. As long as there is a lack of normal work, then we must ask the air conditioning repair master to take a look
2. Check the air conditioning filter, if the air conditioning is working properly, but not cool air, it is likely that the air conditioning filter is too much dust, with a special filter cleaner spray and then clean
3. Check whether the refrigerant is not a lack of, that is, often referred to as Freon, if the refrigerant is not enough to add fluoride. To add fluorine, together with a careful check of the air conditioning is not the phenomenon of air leakage. This situation is mostly found in the use of three or four years of air conditioning, is also a normal phenomenon, but this situation will only appear cooling can not, if not cooling at all but also carefully check whether there is a leakage phenomenon.
4. If the air conditioner works normally, there is no such phenomenon, you can check the fan working condition, if the fan is very small, then it is likely that the fan motor aging, replace the fan motor can be.
5. Check whether the air conditioning ventilation pipe is longer, if the ventilation pipe is too long will affect the effect of indoor heat conduction to the outdoors. Advocate for the replacement of outdoor air conditioning direction, try to shorten the ventilation pipe
6. If the air conditioning works normally, only the air conditioning blowing mouth cool air, the room other areas do not feel the cool air or the effect is not obvious, then the air conditioning horsepower is likely to be too small, and the room is too large caused by the advocacy of replacing the air conditioning horsepower
Air conditioning how to overhaul the common problems?
1, air conditioning power
The overhaul approach: boot on the burn fuse and fuse. Service phone
1, our representatives will provide you with professional and answer!
Fuse: clarifies that there is a short circuit in the circuit, the multimeter should be used to detect the resistance value and determine the short circuit part of the circuit. Together, can also use the split method to check, such as by disconnecting the transformer primary winding, power on the test machine, if it is not yet good, elucidation of the burn is due to the presence of a short circuit varistor or ceramic capacitor, transformer or rectifier, etc. there is a short circuit phenomenon.
The fuse: the multimeter can be used to communicate with the gear measuring transformer secondary and primary whether to reach 220 volts and 10-13 volts, if so, and then use the multimeter DC measurement 7812 and 7805 there is no +9-12 volts and +5 volts, can be effective in distinguishing between faults.
2, air-conditioning relay circuit
The repair method: the difference is that the relay is damaged or integrated success driver module is damaged
After the power on, the buzzer sounded, the whole machine can not work, mostly integrated success driver module is damaged;
After the power on, some of the function is not normal, mostly relay damage, listen to the relay suction sound to determine the relay is the contact The relay is not working properly, so listen to the sound of the relay clicking to determine whether the relay is a contact or a burnt out coil.
No suction sound, the relay coil burnt out;
Also be able to use a multimeter ohm to determine good or bad, closed power, the first measurement coil resistance value. General normal resistance value of a few hundred ohms, if infinity or 0, the relay is damaged;
Demand contacts, if the resistance value of 0, the contact adhesion.
3, air conditioning temperature-sensitive circuit fault
The repair method: thermistor is a negative temperature coefficient of resistance, the lower the temperature, the greater the resistance;
At 25 degrees, the resistance value of about 5-20KΩ or so. Available multimeter ohm measurement, resistance value is very small or infinity, the thermistor damage to be replaced.
4, air-conditioning reset circuit
The repair method: the reset voltage is a delayed rise in voltage, the multimeter DC voltage survey.
If the survey is not clear, then use an oscilloscope to detect. Detection of a baseline floating, and then become high level, above is the reset voltage start process. If the baseline is not floating, the reset circuit is faulty.
5, air conditioning remote control receiver circuit
The repair method: power on, with a multimeter DC block measuring the signal terminal voltage to ground and the receiving end of the power supply, the normal value should be +5 volts for the power supply pole voltage, the signal pole voltage is +2.5 volts. Common problems are capacitor breakdown or receiver head damage.
The drain pipe is mainly used for condensate discharge from the indoor unit, it is connected to the indoor unit with a soft connection, to be clamped with a clamp, if the connection is not tight, condensate will flow out of the gap.
The solution is here: after connecting the indoor unit and the drain pipe, carry out a drainage test to ensure that the connection is tight and will not leak. 3, condensate drainage The condensate drain of the indoor unit is blocked or the slope of the drainpipe is not enough, which will lead to poor condensate drainage and accumulation in the indoor unit on the water catchment tray, the water catchment tray is full of overflow to soak the ceiling. The solution look here: construction to ensure that the condensate drainage slope can not be less than 1/100, drain pipe and indoor machine connected to the indoor machine before checking whether the indoor machine drain is dirty or blocked, after the completion of the construction of the drain pipe must be full of water experiments, to ensure that the condensate can be discharged smoothly. 4, the drain did not pack insulation condensate drain pipe inside the condensate flowing through the lower temperature, so the construction must be required to pack insulation cotton, part of the engineering company in order to save costs did not pack insulation cotton condensate drain pipe, resulting in condensate condensation on the outside wall of the drain pipe, which leads to water leakage. Solution: All condensate drain must be wrapped with insulation cotton, and the standards and requirements of insulation cotton and copper pipe insulation cotton.National service area:
