What's wrong with the outdoor unit of the air conditioner not turning on?

Causes and solutions: 1. Circuit failure, you should check whether the connection lines of the indoor unit and outdoor unit of the air conditioner are normal; 2. If there is a power outage, you should check whether the power plug is loose and fallen off; 3. If the condenser fails, you should Check whether the condenser has not been cleaned for a long time; 4. The computer motherboard is faulty, make sure the motherboard is used normally; 5. The air conditioning fan is faulty, check whether the fan motor coil is damaged, whether the fan screws are loose and fall off, whether the fan capacitor is damaged, etc.; 6. Refrigerant leakage, make sure there is no refrigerant leakage; 7. The temperature reaches the set value; 8. Heat dissipation problem, make sure the radiator is not blocked, etc.

There are many reasons why the outdoor unit of the air conditioner does not rotate. The common ones are as follows:

1. Circuit failure: The connection line between the indoor unit and the outdoor unit of the air conditioner is broken, which will cause the outdoor unit to not rotate. The outdoor unit cannot receive power, so the outdoor unit will not work.
2. Power outage: If there is a sudden power outage at home, or the power plug becomes loose and falls off, and the air conditioner has no power, its outdoor unit will not rotate.
3. Condenser failure: The air conditioner condenser fails. For example, the condenser has not been cleaned for a long time, resulting in poor cooling effect. The air conditioner may turn on the overheat protection function and the outdoor unit will not rotate.
4. Computer motherboard failure: The operation of the indoor and outdoor units of the air conditioner is controlled by the computer motherboard. If there is a problem with the computer motherboard, the outdoor unit may not operate.
5. Air conditioning fan failure: The fan motor coil is damaged, the fan screws are loose and fall off, the fan capacitor is damaged, etc., which will cause the outdoor unit to not rotate.
6. Refrigerant leakage: The air conditioner refrigerant leaks, causing the air conditioner to lack fluorine. Without refrigerant, the compressor usually will not work, so the outdoor unit of the air conditioner will not operate.
7. The temperature reaches the set value: If the indoor temperature reaches the set temperature, the air conditioner does not need to be cooled, and the outdoor unit of the air conditioner will not operate at this time.
8. Heat dissipation problem: The radiator in the outdoor unit of the air conditioner absorbs a lot of dust, garbage and other dirt. The dirt blocks the fan shaft and prevents the fan from running.
9. Voltage problem: When installing the air conditioner, please ask a regular installer to first check whether the power supply voltage meets the standards. If it does not meet the standard, the user is required to change it to the standard voltage before use.
10. Water leakage and fluorine leakage: Pay attention to whether the air conditioner is leaking water or fluorine leakage. If any problem is found, stop using it immediately.

If the above situation causes the outdoor unit of the air conditioner to not rotate, you should ask professional maintenance personnel to come to inspect and repair it.
