How to come back if the bathroom ventilation fan does not inhale

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.

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.

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.

now we have two and tw

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.

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.
