What is the reason why the fan of the air conditioner does not turn and the compressor does not work

Causes and maintenance methods for failure of air conditioning and refrigeration outside unit not working:

1. The difference between the indoor temperature and the set temperature is too small, resulting in the air conditioner not working; Reset the refrigeration temperature.

2. The temperature probe or temperature sensor of the air conditioner is damaged; Timely repair or replacement.

3. Check whether the fan of the air conditioner is working

If the fan compressor does not work, it is mostly due to damage to the air conditioner compressor or starting capacitor; Timely repair or replacement.

Air conditioning fans and compressors are not working; It can detect whether the outdoor unit has sufficient voltage; Check for exclusions.

4. If the voltage is too low or unstable, the air conditioner will be protected by low voltage; Check for exclusions.

5. The four-way valve of the air conditioner is stuck, and the external unit does not work; Check for exclusions.

6. Lack of fluorine in the air-conditioning system; Fluoride the air conditioner in a timely manner.

If the air conditioner is running in heating mode when the outdoor ambient temperature is high, this situation may occur, which is normal;

If the air conditioner is running in refrigeration mode, the compressor of the outdoor unit is running but the fan motor of the outdoor unit does not rotate, it is a relatively large fault.

Because when the air conditioner and refrigeration are running, if only the compressor is running and the fan motor of the outdoor unit is not working, the compressor will soon have the exhaust pressure or the exhaust temperature is too high protection or even the compressor overload protection. This kind of failure is mostly caused by the aging of the capacitor of the fan motor of the outdoor unit or the burning of the fan motor.

Suggested treatment:

1. Measure the capacitance of the outdoor fan motor and the winding resistance of the fan motor to see if it is normal;

2. Check the working status of the fan motor relay and the wiring status of the power supply line of the fan motor.

There are many possible reasons why the fan of the outdoor unit of an air conditioner does not turn and the compressor is running, and here are some common reasons:

Fan motor failure: If the fan motor is damaged or malfunctioning, the fan will not work properly. This can be caused by a circuit problem, a burned motor winding, or a worn bearing on the ruler plexiculturer.

Stuck or deformed fan blades: If the fan blades are stuck by debris or deformed by impact, the fan will not rotate properly.

Faulty circuits: The circuitry of the outdoor unit of the air conditioner may be faulty, such as damaged switches, relays, or fuses, etc., which may cause the fan to not work properly.

Faulty capacitor on the fan: The capacitor on the fan may fail, causing the fan to fail properly.

Faulty control board: Components on the control board may fail, causing the fan to fail properly.

The above are some of the common reasons, but this is not an exhaustive list. If you encounter the problem that the fan of the outdoor unit of Zhengyan air conditioner does not turn and the compressor runs, it is best to ask professional and technical personnel for maintenance and maintenance.

The fan of the outdoor unit of the air conditioner does not rotate but the Bimu compressor runs may be one of the following reasons: first, it may be that the motor is damaged or the circuit is short-circuited, resulting in the fan not working normally; Secondly, it may be that the capacitor is faulty, the capacitor power is insufficient or the circuit is not working, resulting in the fan not operating normally; In the end, it may be that there is a blockage inside the fan, which will also cause the fan to not function properly.

When the fan of the outdoor unit of the air conditioner does not rotate but the compressor is running, it will cause poor air circulation and reduce the cooling effect. In such a situation, it is necessary to carry out repairs and inspections in a timely manner. If the problem is relatively simple, you can replace or repair the motor, capacitor and other parts by yourself, but if the problem is more serious, it is recommended to ask a professional to deal with it to avoid damage or safety hazards to the equipment.

The problem that the fan of the outdoor unit of the air conditioner does not rotate may affect the operation and safety of the air conditioning equipment, so users need to pay attention to care and maintenance when using it. Usually pay attention to observe the operation status of air conditioning equipment, find problems in time and deal with them. At the same time, the equipment should be maintained regularly to prolong its service life. Lament!

If the cooling fan of the outdoor unit does not rotate, the heat dissipation performance of the air conditioner is not good, and the refrigeration performance will deteriorate, and it may even cause the air conditioner to burn out due to high temperature.

This can be seen in two ways:

1. Normal operation, when the ambient temperature is relatively low, if the air conditioner hasLow-temperature refrigerationfunction, turn on the refrigeration mode, and the compressor will always run. The fan of the outdoor unit runs for a while, stops for a while, and sometimes runs at a low speed. The same goes for it, if there isHigh temperature heatingfunction, when the ambient temperature is high, this phenomenon will also occur.

The reason is that through the natural convection of air and the radiation of the heat exchanger, the heat exchange is completed, and there is no need for a fan to strengthen the heat exchange.

2. Operation failure, if the fan stops, the compressor will run for a short time, and then the compressor will also stop running.

The fan of the outdoor unit of the air conditioner does not rotate to run the compressor, it is recommended to use a multi-purpose test to see if the fan terminal has a voltage of 220V, if the voltage is normal, it is recommended to measure the high capacitance capacity of the wind, which is generally caused by the bad capacitance of the fan.

Causes and how to fix them.

1. The mode of the air conditioner setting is incorrect. For example, the mode set by the remote control is air supply, heating, dehumidification, etc., and the outdoor unit will not start.

2. The temperature set by the air conditioner is too high. When the set temperature adjusted by the remote control is higher than the temperature of the room, the outdoor unit does not work.

3. When the accessories of the air conditioner are damaged, the outdoor unit does not work or the whole unit does not start after the corresponding fault** of the indoor unit.

4. When the outdoor unit is protected by high and low, the outdoor unit will stop working. For example, the outdoor unit condenser has poor heat dissipation and high pressure protection.

5. Low voltage protection of the outdoor unit, when the refrigerant is insufficient, the high and low voltage protection switch jumps open, the circuit board of the indoor unit detects the signal, and the outdoor unit stops working and does not start.

The fan of the air conditioner does not start.

6. The outdoor fan does not work. If the fan motor of the external unit is damaged or the starting capacitor of the fan fails, the external machine will stop working when the temperature protection machine is reached.

7. The indoor tube temperature sensor has no change in open circuit, short circuit or temperature parameters, and the circuit board detects fault shutdown protection, and the external unit does not start.

8. The open circuit of the ambient temperature sensor of the indoor unit will be short-circuited.

9. The indoor fan does not work. The feedback signal line of the internal fan was bitten off by mice, the motor of the internal fan was damaged, and the starting capacitor of the internal fan failed, which caused the circuit to detect the protection and shut down.

10. The main control circuit board in the room is damaged, and the external unit does not work.

The fan of the air conditioner does not start.

Solution 1:

There's a capacitor like a big battery in it, have you ever started it without or with low fluorine? It's good to change the capacitor and forget to charge fluorine.

Solution 2:

It shouldn't be the voltage, you check if it's powered on.

If the compressor does not start the fan, it means that the pressure of the high pressure of the air conditioning system is too high or too hot, resulting in excessive current. The principle of air conditioning heating is that when the air conditioner starts heating, the freon will be pressurized by the compressor and become a high-temperature and high-pressure gas, and then enter the condenser of the indoor unit, and then the condensation is liquefied and exothermic, and then the indoor air is heated, and the indoor temperature is increased.

The general situation that the air conditioner compressor does not start is caused by long-term operation under the lack of Freon, and it is necessary to supplement the freon for the air conditioner, or the power wire socket is not in good contact, and the power wire diameter is thin or aging, so it is necessary to check whether the power wire is aging and replace it in time. The air conditioning compressor plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circuit. Air conditioning compressors are generally installed in outdoor units.

The air conditioning compressor extracts the refrigerant from the low-pressure area and sends it to the high-pressure area for cooling and condensation after compression, and dissipates heat into the air through the heat sink, and the refrigerant also changes from gaseous to liquid, and the pressure increases.

1. The troubleshooting of the compressor of the outdoor unit of the air conditioner is as follows: When the compressor of the outdoor unit of the air conditioner does not start, the first thing to check is whether there is a problem with the power supply circuit of the outdoor unit, the starting capacitance of the compressor, the starting relay of the compressor, and the compressor itself.

In your case, there may be a problem with the fan of the air conditioner, so it is possible to change the motor. To repair it, it's fine.

When the compressor of the outdoor unit of the air conditioner does not start, the first thing to check is whether there is a problem with the power supply circuit of the outdoor unit, the starting capacitor of the compressor, the starting relay, and the compressor itself.

Compressor overheating, high pressure and low pressure protection! Compressor starting capacitor is bad!

It is recommended to check the fluorine piezo current!

The outdoor unit fan and the compressor fan generally come from the same contactor-controlled power supply, so there is no direct relationship between the fan and the compressor.

Reasons why the fan does not turn and the compressor does not work:

1. The contacts of the contactor are damaged, resulting in the inability to provide power to the fan.

2. The contact flusher coil does not get the base information electricity, and the contactor cannot provide power supply for the fan without engagement.

3. When the actual temperature of the indoor unit reaches the set temperature, it is normal for the fan and compressor not to rotate.

4. The circuit board of the air conditioner is faulty.

5. The air conditioner is alarmed and shut down due to lack of fluorine or fluorine leakage.
