What are the best ways to repair air conditioner appliances

Turn on the machine to see what the fault is, and eliminate it according to the fault phenomenon.

This can't be helped, specifically! Air conditioner distribution equipment system three!

Electrical appliances; With a multimeter! One by one, it will always be measured! Or something bad just swap it out! Such as a computer board!

System; Mostly out of leaky potions! Or add a potion! Nothing else!

Equipment; If the equipment is broken, replace it!

Tool; Electrical appliances - multimeters.

System - steel bottle, high and low pressure gauge, soapy water (for measuring pipe leakage), equipment - wrench, screwdriver, etc.!

Broken air conditioner? In my eight years of aircon maintenance experience to tell you how to solve these faults, you should avoid a lot of detours.

First: When you encounter an air conditioner failure**, you can go to the [network] air conditioner failure** to inquire and reduce the brand and model of the air conditioner. Universal remote control** find.

The query of the corner can go to the universal remote control.

In the encounter, when the faulty air conditioner must be behaved in strict accordance with the scientific procedure, if the situation is not clear, the failure is unknown, when the uncertainty of blind action, dismantling.

The consequence of this often expands existing failures, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

No refrigeration or poor air conditioning.

The most common problem is the lack of fluorine air conditioners.

Turnkey return tubing via the first touch.

temperature to determine if the machine is cold Check that the fan speed may be lower and dirt and dirt to clean or replace.

If the pipe does not cool down, the pipe may have been flattened.

The return air temperature is not too cold and then penetrates deep into the air to determine.

The cold air intakes were also frosted fluoride.

Try the slowly scattered cream again, if there is a fluoride deficiency, it is a good decision, and it is not difficult to see.

Exhaust by age is not focused enough.

Stone strings are also common to determine by turning off fluoride.

The high-pressure scale must look dirty, and the refrigeration will slow down.

I wish you a better new year, docile, all wishes come true, good health, and happiness.

- Finally, I want the work to be carried out smoothly, and the air conditioner is repaired for the first half of --- happiness

- If you think it's good, you will have a good answer, give a good review, and wish you a better life ---

1. First of all, check whether the air conditioner is operating normally, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit, as long as one of them is not running normally, you need to ask a professional master to come to the door for maintenance.

2. Then check the filter screen of the air conditioner, if the air conditioner can be started normally, but it can not emit cold air, it is very likely that the filter screen is too dusty, and the better way is to spray it with that special filter cleaning agent.

3. If the air volume of the fan is very small, then it may be that the fan motor is old and needs to be replaced with a new one.

4. Check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, add freon, and check whether the cold circulation system has air leakage, if there is air leakage, you have to make up for the leakage.

5. If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, only to the air conditioner air vent to have the air conditioner, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, it will be better to replace the air conditioner with a little more horsepower.

6. If the ventilation pipe of the air conditioner is installed for a long time, it may lead to a poor effect of transferring indoor heat to the outdoors, so that the refrigeration is not very obvious The hood is changed, and a better position should be found to reinstall it, and strive to shorten the ventilation pipe.

You can find a professional air conditioning maintenance and fluoride service company to repair and fluoride. The reason why the air conditioner is not refrigerated, first check the operation of the air conditioner, the filter, the refrigerant, the cold circulation system, the fan, etc., and repair the fault in time. The above situation is normal, check the air conditioning ventilation duct, and reinstall it if it is too long.
