If the water temperature is high and the fan doesn t start, what happens when the air conditioner fa

The situation that the water tank does not rotate can be checked one by one according to the following three points:

1. Whether the water temperature meets the requirements:

Most of today's car radiator fans use electronic temperature control to work, so generally only when the water temperature in your car reaches the required temperature, the fan will start to rotate normally, if the temperature is too low, the radiator fan will not be able to rotate. Therefore, when your car radiator fan does not rotate, you should first check whether the water temperature meets the requirements.

Second, the relay is faulty:

If the water temperature meets the requirements and the car radiator fan still does not work, then there may be a problem with the relay of the fan, if the relay fails, the car radiator fan will not work.

3. Temperature control switch.

There is a problem: If there is no problem in the above two aspects, then it is necessary to check the temperature control switch, this place sometimes has some faults, which will also have a certain impact on the operation of the car radiator fan, so you should also pay attention to check.

There are three scenarios for the fan to start:

1. The water temperature is too high.

2. Turn on the AC switch of the air conditioner.

3. The pressure of the high-pressure part of the air conditioner is too high.

What you say about the high temperature of the water is just your own feeling, and you don't know how high it is.

If it is true that the water temperature is very high and the fan does not start, it may be that the fan is damaged, the coolant temperature sensor is damaged, the line is faulty, the fan relay or fan controller is damaged, etc. What the specific reasons are should be looked at specifically.

The air conditioner is because the compressor is finished, and the condenser begins to be made to dissipate heat. So he cooled the fan and started to spin, so as soon as there was a problem with the pressure sensor of the air conditioner, the fan would start to spin directly. This is normal!

It may be that the fan is faulty, the water temperature will be normal after the electronic fan troubleshooting, the electronic fan does not work, first check whether the connector is in poor contact, check the power supply and tie-up of the electronic fan, check whether the fan is stuck, check whether the fan motor is burned, etc., these factors will cause the electronic fan to not start.

Dongfeng Peugeot 206 water temperature is high, the electronic fan does not turn on the air conditioner fan, what is going on I also agree with the water temperature sensor said upstairs, and the air conditioner fan is controlled by a pressure switch.

1. The engine temperature is too high due to insufficient cooling water in the cooling system, and the coolant needs to be added after the engine is cooled;

2. The engine temperature is too high due to the loose or broken belt of the water pump and fan, and it is necessary to go to the maintenance shop to replace the relevant parts;

3. The radiator shield net or the radiator core ventilation channel is blocked by debris, resulting in poor heat dissipation, resulting in high engine temperature. It is necessary to replace the heat dissipation shield or clean up the debris;

How many degrees is the water warm? Is it actually measured? In order to reduce friction consumption in modern engines, the normal water temperature is set to 105 degrees.

Volkswagen double thermostat double circulation system, the upper (cylinder head) circulation system thermostat is set to 87 degrees to open, the lower (cylinder block) circulation system thermostat is set to 105 degrees before opening, so that the lubricating oil is much thinner, the friction resistance is reduced, and the fan is set to the water temperature is not enough 85 degrees and does not turn. Sometimes you think the water temperature is high, but it's not that high.

You can read the water temperature data with the car fault diagnosis instrument, and then use the multimeter to measure the water temperature sensor.

1. If the water temperature is very high before starting the car, the car may not be easy to start, and there are many reasons for the high temperature of the car.

2. The cooling fan does not rotate, the coolant is insufficient, the water temperature gauge is faulty, the water tank is blocked, etc., which may cause the high temperature of the car. If the water temperature gauge is normal, when the temperature reaches the red warning line, slow down, and when it is safe to do so, pull over to the side of the road, taking care not to turn off the engine.

3. Do not pour cold water on the engine, wear gloves and gently unscrew the lid of the water tank, wait for the water vapor to be slowly discharged, and after the pressure of the water tank drops, add cold water or antifreeze.

4. Regularly check the body to ensure that there is no dirt around the water tank, which causes the heat dissipation capacity of the water tank to decrease.

1.Whether the water temperature has reached the requirements: Most of today's car radiator fans use electronic temperature control to work, so generally only when the water temperature in your car reaches the required temperature, the fan will start to rotate normally, if the temperature is too low, the radiator fan will not be able to rotate.

So when your car radiator.

2.Relay failure: If the water temperature meets the requirements and the car radiator fan still does not work, then there may be a problem with the relay of the fan, if the relay is faulty, the car's.

3.There is a problem with the temperature switch: If there is no problem with the above two aspects, then it is necessary to check the temperature switch, this.

This is generally a temperature sensor head is broken, and it doesn't cost much to go to the repair shop to replace one.

The very simple way is to go to the repair shop to change the temperature control.

If the water temperature is high and the fan doesn't start, what happens when the air conditioner fan starts?

Car cooling fans do not work immediately after the vehicle is started, provided that the refrigeration system of the air conditioner is not turned on. Because the cooling fan works according to the water temperature of the antifreeze to decide when to rotate, generally when the water temperature reaches about 108 degrees, the low speed of the cooling fan starts to work, and the water temperature reaches about 118 degrees, the high speed of the cooling fan starts to work. So it's not as soon as the vehicle starts up that the cooling fan starts to turn.

When the car turns on the air conditioning and refrigeration system, the compressor of the air conditioner starts to work, which loses part of the engine power, so the engine load increases, and in order to prevent the engine load from increasing again, the cooling fan will start working immediately.

Summary. Hello dear, happy to answer your <>

If you're talking about car air conditioning systems, there could be the following reasons:1Air conditioner pressure switch malfunction:

The air conditioning system will automatically control the work according to the high and low pressure, if the pressure switch is faulty, it may cause the air conditioner fan not to start. However, when the air conditioner is turned on, the air conditioning system will increase the pressure through components such as the compressor to allow the air conditioning fan to start working. 2.

Radiator failure: It may be due to the accumulation of dust inside the radiator, or there is a blockage that prevents air circulation and heat dissipation. The car air conditioning system may automatically turn on the fan in order to prevent high temperatures, but if the fan itself fails, it cannot be turned on.

3.Fan circuit failure: The fan circuit may have problems with relays, fuses, fan motors, etc., causing the fan to not work properly.

If you are referring to household electric fans, there may be the following reasons:1Poor power cord contact:

It may be that the plug or socket is damaged or detached, causing the electric fan to not work properly. 2.Switch failure:

The switch of the electric fan may malfunction, causing the stool cracked fan to fail to start. In this case, you can try unplugging the power cord and checking the switch. 3.

Motor failure: The motor of the electric fan may be damaged or burned out, causing the fan to fail to start. 4.

Other reasons: such as capacitor failure, overheating protector failure, etc., may also affect the start of the electric fan in the source section.

If the water temperature is high and the fan doesn't start, what happens when the air conditioner fan starts?

Hello dear. We'll be happy to answer for you. You can use a computer to read the relevant fault codes and data streams.

Observe it. Whether the water temperature is normal, or if this fault can be unplugged from the water temperature sensor, test whether the fan can be started and does not turn, consider that there is a problem with the engine computer, if it can be turned, consider that the signal of the water temperature sensor is not accurate, resulting in the computer not connecting to the relay on the fan. I hope I can help my relatives, I wish my relatives good health and all the best!

1. Poor contact of the air conditioning switch: If the air conditioning switch is not in good contact, it cannot control the normal start of the car air conditioner, and the two cannot be connected, so the fan of the car air conditioner does not rotate. In this case, replace the air conditioner control switch, and pay attention to whether there is a short circuit in the connecting wire of the switch.

2. The fan motor coil is damaged: If the fan motor coil is damaged, the fan cannot supply energy normally, so it does not rotate. In this case, the coil of the fan motor of the wind wheel should be inspected and repaired, and it can be directly replaced if necessary.

3. Fan bearing falling off: When the fan bearing falls off, when the air conditioner is turned on, only the bearing idles and the fan cannot rotate normally, in this case, the fan bearing should be reinstalled and fixed.

4. The water temperature does not meet the requirements: most of the car fans use electronic temperature control technology to work, and the air conditioning system can only work normally if the water temperature reaches the standard. If it is normal for the air conditioning fan not to rotate because the water temperature does not reach the standard, Musou only needs to heat the car to make the water temperature reach the normal standard.
