How do you come back if the bathroom ventilation fan doesn t inhale?

Bathroom ventilation fan does not inhale how to come back exhaust fan.

There are two reasons for not inhaling, one is that the exhaust air volume of the exhaust fan is not too small, he is inhaling and can not meet the needs of the indoor exhaust fan, there is no other way, only to replace the exhaust fan with a relatively large air volume, and the other is that the exhaust is not smooth, it may be a check valve.

Blocked, it may also be that the air duct is blocked, resulting in the exhaust fan exhaust air can not be discharged, resulting in return air, this situation needs to be unobstructed on the air duct, static electromechanical technology can provide you with the answer to the problem during the use of the exhaust fan product.

Jingdi electromechanical technology can provide you with answers to your questions during the use of exhaust fan products.

First of all, check whether the fan motor rotates? If the motor does not rotate, it is likely that the starting capacitor inside has failed, and a new capacitor is replaced; If the motor is rotating, it is likely that the filter is too dirty and needs to be removed for cleaning.

You said that the bathroom ventilation fan does not inhale, what's the matter? Isn't this likely? The wiring is wrong, change the wire and try it. It's probably inhaled into the house rather than outside.

The ventilation fan is exhaust and does not inhale. You can install a make-up air.

Check the exhaust pipe, if the exhaust pipe is not through, the gas will not be discharged.

The exhaust air duct is blocked, and the gas cannot be discharged.

Here's how to replace the toilet ventilator:

1. Turn off the ventilation fan switch first, and then the exhaust fan.

It is not electrified, and it will be safer to disassemble. If you are not at ease, we can turn the electric switch in the bathroom.

The gate pulls down to cut off the power to the entire bathroom.

2. The exhaust fan panel is usually stuck on the main body, we use a knife and other items to insert the gap in the panel, pry the panel down, pry the exhaust fan panel out a little, we hold the edge of the panel and pull it down to remove the panel. Some panels are fixed by spring buckles, after the panel is pried a little, we have to find the position of the spring buckle, and press the spring buckle with our hands to take out the panel.

3. After the panel is removed, we can see the fixing screws around the main body of the exhaust fan, and we can use a screwdriver.

Loosen the set screws and tilt it out with the body of the quiet exhaust fan tilted inward. After the main body of the exhaust fan is pulled out, we can see the ventilation duct connected to the vent behind the main engine, and we tear the aluminum foil tape at the connection of the ventilation duct to separate the ventilation duct from the main engine vent.

4. Snap the ventilation fan of the same size into the original card slot, connect the power supply, and then fix the four corners of the exhaust fan.

The first situation is when the ventilation fan is blocked by dirty things. If it's blocked, then even if it's still spinning, it will pump very little or even at all.

2. Pretend to be reversed. When we install, we must pay attention not to install the fan blades of the ventilation fan upside down. If it is reversed, then it will only turn, but it will not have the effect of pumping. The principle of the fan is also like this, everyone should be very clear.

Why does the bathroom ventilation fan only turn and not extract? How to repair the ventilation fan?

How to fix the ventilation fan if it doesn't turn? 1. Check the socket.

First of all, we can plug in the power supply, and after the power is turned on, we hear the motor humming, then we need to remove the fan blades. Be careful in the process of dismantling, if the fan blade can rotate but does not pump, it means that its motor is broken.

2. Repair the motor.

After determining that the motor is broken, we can gently remove it. Look at the thread inside to see if it is intact and if there is any place to fall off. If it is dusty inside, you can use a rag to clean up the dirt.

If that doesn't work, then take it to a professional place and let a professional do the repair. If you can't dismantle it, you can also ask a professional to come to your door to inspect it. If you have used the motor for a long time, it is more convenient to replace it with a new one.

Why does the bathroom ventilation fan only turn and not extract? How to repair the ventilation fan?

What are the reasons why the ventilation fan does not rotate? 1. Lack of lubricating oil.

If the lubricating oil inside the motor has dried completely, then it will not spin. When this happens, we can remove the motor and see if there is an oiling place. If there is, you can add some lubricating oil to it, so that it can be re-turned.

Add the right amount, not too little and not too much.

2. Long time.

If the motor is used for too long, then the capacitor inside may be damaged, resulting in non-rotation. It is also possible that the machines inside are glued together, and in this case, we only need to gently tap the motor from all sides.

Why does the bathroom ventilation fan only turn and not extract? How to repair the ventilation fan?

A ventilation fan in the bathroom is very important, without it, the air in the bathroom is terrible. When it breaks, we have to learn to repair it. If you can't, you need to ask a professional to repair it.

There are two reasons why the exhaust fan does not inhale, one is that the exhaust air volume of the exhaust fan is not too small, he is inhaling and can not meet the needs of the indoor exhaust fan, there is no other way, only to replace the exhaust fan with a relatively large air volume, the other is that the exhaust is not smooth, it may be that the check valve is blocked, or it may be that the air duct is blocked, resulting in the exhaust fan exhaust air can not be discharged, resulting in return air, this situation needs to be unobstructed on the air duct. Jingdi electromechanical technology can provide you with answers to your questions during the use of exhaust fan products.

One is that the exhaust air volume of the exhaust fan is not too small, he is inhaling and can not meet the needs of the indoor exhaust fan, there is no other way, only to replace the exhaust fan with a relatively large air volume, the other is that the exhaust air is not smooth, it may be that the check valve is blocked, or it may be that the air duct is blocked, resulting in the exhaust air of the exhaust fan can not be discharged, and the return air is generated, which needs to be unobstructed.

The exhaust fan cannot be pumped normally, and the common reasons are mainly the following:

1. First of all, you can check whether the power supply of the lower exhaust fan is normally energized, and whether the plug and socket are electrified;

2. In the case of power failure, open the shell of the exhaust fan to see if the motor and other circuits inside are normal, whether there is looseness, aging, etc.;

3. See if the exhaust fan has been used for a long time, resulting in the fan blades accumulating a large amount of dust or swag, resulting in the motor being unable to drive the fan to rotate and unable to extract air;

4. If the motor capacitor fails, this suggestion is to report to a professional maintenance master to repair and replace.

1. The power is not enough, the exhaust air volume is too small, and the feeling is not obvious, the probability of this phenomenon is not large.

2. The exhaust pipe is blocked and the ventilation is not smooth, and the exhaust channel is an important part of the work of the exhaust fan. When installing the exhaust fan, it is necessary to take into account the direction of the exhaust duct and do a good job in the duct layout.

3. Some families in the decoration construction, in order to the overall appearance, to the bathroom to hang a ceiling, and the exhaust fan placed in the ceiling, such a design is very good, not only to save space, but also to beautify the environment, so that there is a problem to pay attention to, the bathroom exhaust fan in the completion of acceptance, must pay attention to whether the exhaust pipe extends into the flue, whether the surrounding gaps are blocked.

From the above, we can see that whether it is purchased or installed, it may be the reason why the bathroom ventilation fan does not exhaust, so special attention should be paid to the purchase and installation of the product.

The toilet ventilation fan should not be left on all the time, because the bathroom ventilation fan will reduce the air pressure in the bathroom all the time, so that the gas in the toilet sewer may be pressed into the toilet due to negative pressure, resulting in an increase in the bacterial content in the bathroom. At the same time, the bathroom ventilation fan has been turned on, and the damage rate of the ventilation fan will be relatively high and the life span will be shortened for a long time, so it is not recommended to leave the bathroom ventilation fan on.

1. Generally, when you go to the bathroom, turn on the ventilation fan and turn it off 5-10 minutes after leaving.

2. If you take a bath, you can turn on the ventilation fan to discharge the moisture and heat from the bathroom, and you can turn it off after taking a bath and seeing that the heat and moisture inside are discharged.

3. When the ventilation fan is turned on in the bathroom, you can open the door a little, which is conducive to air flow. If the door is closed and the exhaust is closed, there is no channel for supplemental air, and the exhaust resistance is very large, and the effect of ventilation will be relatively poor.

The bathroom is indispensable in our daily life, and our cleaning, defecation, and washing all depend on the bathroom, and the installation of ventilation fans in the bathroom is in line with national standards. What is the function of a bathroom ventilation fan? Bathrooms must be ventilated to remove harmful gases and odors.

If you don't install a ventilation fan, the smell of the bathroom will spread into the room. Sometimes we find that the ventilation fan in the bathroom is turned on, but it takes a long time for it to be activated. Today, let's take a look at the reason why the bathroom ventilation fan is activated after a while.

1. Flick the fan blade with your hand to feel if there is a lot of resistance. If there is a type early, it is a lack of oil to cause difficulty in starting, and the shaft end lacks lubrication and needs to be filled with lubricating oil.

2. The motor winding has been burned by the leakage, the degree of insulation has decreased, and there is a slight short circuit in the winding, and the motor needs to be replaced.

3. The starting capacitor is defective.

4. Poor contact between the joints of the wire or the switch.

5. When the quality of the motor of the exhaust fan is too poor, there will also be such a problem, the dust is seriously heated for a period of time, resulting in the motor holding the shaft, the motor can be disassembled and polished with fine sand, clean the bearing, and then add lubricating grease.

The above is the content of the bathroom safety tips that I want to talk about today.

The ventilation fan in the bathroom at home does not rotate due to the following reasons:

1.Capacitor failure If the exhaust fan stops running, we first need to turn on the switch of the exhaust fan, let it be energized, and then listen carefully to whether the exhaust fan has the sound of the humming engine, if there is, it proves that there is no problem with the engine, it may be that there is a problem with the capacitor.

2.The switch spring loses its elasticity.

Of course, there is more than one reason for the exhaust fan strike, in addition to the capacitor failure, there is also a possibility that the spring of the switch has lost its elasticity, because the spring has lost its elasticity, so there will be jamming or poor contact in the process of operation, which will directly affect the operation of the exhaust fan, so we need to carefully check whether the exhaust fan blades are difficult to rotate.

3.Run out of lubricating oil.

In addition, another reason why the exhaust fan does not run is that the lubricating oil inside it has been exhausted, and the lubrication between the shaft and the rotating sleeve is not enough, so the two will be stuck with each other and cannot operate normally. If the internal motor cannot operate, it is equivalent to the human heart cannot beat normally, which will cause the exhaust fan to stop running, and the strike cannot be used normally.

In short, if we encounter the situation of exhaust fan strike, first of all, do not be impatient, only need to eliminate the reasons for its non-operation one by one, and the corresponding treatment can easily solve the problem of exhaust fan not running, and give us a bathroom with fresh air.

There are several possibilities for this.

First check if there is electricity.

Then see if the switch is normal.

Then there is whether the motor is normal.

Let's exclude them one by one.

The reason why the ventilation fan in the bathroom does not rotate may be that the spring has lost its elasticity. Of course, there is more than one reason for the exhaust fan strike, in addition to the failure of the capacitor, there is also a possibility that the spring of the switch has lost its elasticity, because the spring has lost its elasticity, so there will be jamming or poor contact in the process of operation, which will directly affect the operation of the exhaust fan.

It should be caused by the lack of lubrication caused by the oil staining the rotor, and it is really helping you look forward to adoption

The dust is in, the oil is lacking, the bearings are not working, and the circuit is burning.

As long as it's not your power socket problem, if it doesn't turn around, change it, this thing is dirty.

The quality of this ventilator fan and the like is not good in itself.

It's because the environment is humid. The motor inside the ventilation fan may be broken.

The bathroom is the most serious place for moisture and turbidity, so many families will install bathroom ventilation fans, but the occasional small problems in actual use make many users worry, what to do if the bathroom ventilation fan does not turn? Let's find out together!

1. In many cases, the reason why the fan blades do not rotate is the problem of poor maintenance. If the blade is stiff after turning off the power, you should use some lubricating oil to drip into the shaft so that it can be lubricated so as not to affect the motor to drag the blade.

2. In view of the non-rotation of the fan blade caused by wear, the easiest thing is to replace the parts, especially the shaft sleeve, which is easy to burn off if it is worn out.

3. If the capacitor capacity becomes smaller and the fan does not rotate, you can remove the capacitor and replace it with a new capacitor of the same model, it is recommended to choose a capacitor that is 20% larger than the original capacitor, which will have a better rotation effect.

4. If the axial clearance of the shaft is too large, you can choose to adjust the vertical gasket after disassembling the motor. However, remember that when installing the motor back, it should be noted that the rotor must be concentric with the bearing, and the lubrication screws should be slowly tightened diagonally, and finally the shaft should be knocked on the vertical fiber belt shaft with a wooden handle to ensure that it is concentric. It is very easy to disassemble the motor, but it is more difficult to install it back, don't do it casually, otherwise it is easy to repair the fan.

If the bearing is badly worn when the motor is removed, it should be replaced with a new part.

5. If it is because of electrical faults, you can check the wiring lines, sometimes the wires are damaged, etc., and the problem can be repaired.

Generally speaking, the electric fan does not rotate because of the motor, although the fan is small, but it cannot be ignored. When we use electric fans, we should pay more attention to maintenance to prevent rapid aging, and there will be no problem of non-rotating blades. When we overhaul Yu Lu, we will find that the fan is even better than before.
