There is a slight thud when the ceiling exhaust fan is turned on

Faulty air conditioner? I'll tell you how to solve these failures, which should save you a lot of detours.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The press does not start, there is no problem with the temperature setting, but there is no response when the power is on? If the press does not turn the fan, you must look at the capacitor first.

The capacitor bulge needs to be replaced, and the capacitor is checked for power supply.

If there is a power supply, the overload protection of the press checker is the key.

If there is no power supply in the house, first check the connecting wires.

Secondly, it is best to look at the temperature control and replace the temperature control.

The relay is a key point, and the front drive should be judged.

If all of the above are normal, the following things will be easy to do.

Motherboard repair or replacement is subject to the user's decision.

The air conditioner is not refrigerated well or not refrigerated].

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.
