What is an air conditioner board? 5 possible causes of motherboard failure

The circuit board (or circuit board) is the linking and communication part of the air conditioning components. Let’s the article explain what a board is and 5 reasons why the board is damaged!

What is an air conditioner board?

Board (Bo) The circuit is the central part of the air conditioner, this is where many complex components are concentrated . The board is responsible for connecting the components together, between the components will be communicated with each other through the circuit board on the board.

The control buttons of the air conditioner will be on the electronic board of the board.

In conventional (mono) air conditioners, the board will be located in the indoor unit position and perform and control all operations of the machine. While air conditioners use later inverter systems, the board system will be more complicated with 1 main circuit on the cold side, 1 auxiliary circuit on the outdoor unit, and realize many smart and modern features. greater.

Some signs of air conditioner failure

Some signs you can recognize:

• The machine light blinks continuously.
• The machine works 5, 10, 30 minutes and then automatically turns off.
• The machine temperature is not the same as shown on the display.
• Report error codes on the air conditioner control screen.
• The machine does not receive the input power, the board suddenly disconnects.

Recognizing by Remote (hand-held control) such as:

• The indoor unit does not work, does not receive signals from the remote.
• The temperature display light on the indoor unit is not the same as on the remote.
• Use the remote to turn off the power but the machine is still running/not shutting down completely.
• The machine temperature is cooler/hotter than shown on the remote.

Summary of 5 reasons why the air conditioner board is damaged

The air conditioner is not installed properly

Installation location : It is necessary to choose a cool, dry location, avoid direct sunlight and rain, such as doors and windows. Otherwise, the effects of weather will cause the board to be damaged.

In later inverter air conditioners, the outdoor unit board is usually located in a sturdy metal box, the remaining circuit is located in the indoor unit, which needs attention to the appropriate location to ensure the life of the circuit.

Power supply is intermittent, unstable

During use, it is necessary to pay attention to the power supply to the machine, the power supply flickering can cause short-circuiting, short-circuiting, breaking the electronic circuits, affecting other machine parts leading to damage to the whole board. .

The air conditioner is not used properly

The life and cooling quality of the machine will be affected based on the user’s usage, some common errors when using the air conditioner can be mentioned as:

• Using the machine overloaded for a long time.
• Open the machine continuously 24/24.
• Adjust the temperature lower than the environment. The ideal temperature when using the air conditioner should be 8-10 degrees different.
• Change the temperature, adjust the machine indicators continuously.

Do not maintain and clean the air conditioner regularly

Periodic maintenance of the machine is quite important, while using it for a long time, the machine will be dusted and accumulated. When left for a long time, dirt will cause the machine to run at a higher capacity than usual to reach the temperature. At the same time, there are microorganisms and bacteria in the air that can damage the circuit board.

Reasonable time to maintain and clean the machine periodically:

• Household : every 3-4 months for houses open all day, every 6 months for houses open 6-8 hours/day.
• For small and medium enterprises and restaurants : every 3 months
• For enterprises and production facilities : once a month.

The rope is cutting

The location of the machine is also very important, so keep it in a cool, dry place and not let insects and rats enter. There are many cases where the case becomes the nest of creatures and they can bite and damage the circuit, cut the wire.

Above the article has explained the principle and mission of the board and also pointed out 5 reasons for the failure of the board. What do you think about the causes affecting the machine during use? Leave your comment below!
