Fault 1, air conditioning is only blowing, not refrigeration
Many people are full of heads, the question mark said why the first time the machine experienced summer, air-conditioning is not cooling it? These people are no inspection measures in the case of asking these questions are usually ordered back to familiar with the instructions, the control panel on the “A/C” open to show that the air conditioning is opened, but they did not press the button, Speechless is right, do not believe, do not read the instructions, mouth There are plenty of people who asked want to see this article, there is no such person.
Malfunction 2, air conditioning refrigeration effect is bad
Confirm the air conditioning step indeed correct, but still do not feel the air conditioning air conditioning, so first check air-conditioning belt is loose, if no problem is to see the refrigerant (i.e. snow, Freon) is not enough, if there is no problem to check the circuit, if the circuit is not a problem to be cleaned inside and outside circulation filtration and air conditioning evaporator.
Fault 3, air conditioning air flow is small
First check the Baotou North Benz parts to see if the air filter, air inlet may be blocked, and inhaled debris blocked. Import filter in the air conditioning at most is because the filter box, blocked out before the wind. If there is no place to buy, take the wind gun blow down, first use, and then regardless of the use of the motor to remove, and then plug, open fan, one gear test, the speed has not changed, and most of them are variable resistance is broken. The air conditioner filter is installed at the inlet of the inner circulation air duct of the air conditioning refrigerating unit in the driver’s cab, and if the filter is blocked, the air flow or the direct air blow will be blown out.
Fault 4, turn on the air conditioning only listen to the fan, it is not out of the wind
This is a fussy driver, causing a machine problem. The cabin is very dirty, the air is ragged, and even the dust is sucked into the evaporating box by the fan. The evaporation box accumulated a thick layer of dust and dirt, so that it could not absorb air, so that it could not blow out the wind. First boot check, if the compressor can run, it shows that the system pressure is basically normal, no law, only to release the air conditioning.
Note that the air conditioning can be recycled, when the air conditioning do not impatient, from the low side of the table slowly put, and then remove the air-conditioning system decomposition, cleaning, re installed after the time to add air conditioning can solve the problem. Air conditioning should always check the northern Baotou running accessories, condenser fin whether there is dirt, dust and leaves and other debris, if there is, then use high-pressure air, steam or water washed off.
Fault 5, just added snow species, began to refrigeration, and later not refrigeration
First check electrical equipment, such as good, it is best to use a pressure gauge to measure the pressure, high pressure is generally 16, 7KG, low pressure is generally 2, 3KG. If there is no Freon compressor clutch is not absorbed, if there is fluoride, to see whether there is ice jam or dirty block. When the pipe is rotten, check it with soap and water.
Fault 6, turn on the air conditioner to stop the car
Mostly because the engine horsepower is not enough, the engine output power down, not enough to drive the air conditioning, or may be the hydraulic pump power and engine power does not match. General air-conditioning power accounts for 1/10 of the engine, the solution: to increase the power of the engine or reduce the power of the pump, air conditioning when the increase of a little throttle. In addition, check the air filter and Baotou North rush fittings, Chai filter.
