What should I do if the exhaust fan on the bathroom ceiling is broken? How to fix it

First of all, ask a master who understands the principle of electricianism and ask him to bring a multimeter to check it for you.

1.If it is found to be a problem with the wiring or the problem that the switch is not in contact tightly, it can be repaired without removing it.

2.If the exhaust fan is missing lubricating oil, it has to be removed and oiled.

3.If the motor is faulty or the coil is burned, then there is no way to repair it, so I have to remove it and buy a new one.

If I can help you, please give, thank you.

If the exhaust fan is broken, it depends on what the fault is, if it is a line fault or a motor starting capacitor fault, it can be directly repaired or replaced; If the motor burns out, there is no repair value, so replace it with a new one. The integrated ceiling can be changed directly and is not particularly complicated.

It is recommended that the landlord directly remove the old one and replace it with a new one.

The workmanship of the current exhaust fan is not very reliable, and after the failure, the cost of maintenance is sometimes more expensive than buying a new one, and the quality of the repaired is not necessarily as good as the new one.

Of course, if the landlord can do the repairs himself, that's another matter.

Or find a professional to fix it.

First of all, you have to remove it, what is the specific place to repair** The structure of the exhaust fan is very simple, and it should be no problem to repair it yourself.

It's best to find a professional to fix it.

Paisen Zen fan is bad to check and solve, the cause of the failure and the solution:

1. The impeller and the diversion friction of the ventilation fan are damaged or the exhaust fan is faulty due to the lack of oil in the motor bearing of the ventilation fan, which causes non-lubrication, at this time, it is necessary to measure the opening size of the ventilation fan, and then purchase a ventilation fan of the same size according to this size and install it.

2. The switch reed of the piano key loses its elasticity, resulting in the phenomenon of poor contact of the piano key in the process of operation, and the switch of the piano key must be replaced at this time to allow the exhaust fan to operate normally.

3. The power cord of the motor is in poor contact, at this time, you need to re-solder the power cord of the motor, the motor starting capacitor is in poor contact, check the connection of the starting capacitor, at this time, you need to re-solder the starting capacitor, and connect or replace the starting capacitor.

1.First, turn off the power to ensure safety.

2.To remove the cover of the exhaust fan, it is usually necessary to unscrew a few screws.

3.Check the motor for noise, noise, or damage. If the motor is loose, it can be re-secured. If the motor is damaged, it needs to be replaced.

4.Inspect the fan blades for damage or blockage. If the blade is damaged, it needs to be replaced. If the blades are clogged, they can be cleaned with a brush or vacuum cleaner.

5.Inspect the wires for damage or looseness. If the wire is damaged, it needs to be replaced. If the wire is loose, it can be reconnected.

6.Reinstall the cover of the exhaust fan, then turn on the power to test if the exhaust fan is working properly.

If the above methods cannot repair the exhaust fan, it is recommended to ask a professional to repair or replace it.

If the exhaust fan is broken, it should be checked and solved, and the causes and solutions of the failure should be solved

1. The impeller and the diversion friction of the ventilation fan are damaged or the exhaust fan is faulty due to the lack of oil in the motor bearing of the ventilation fan.

2. The switch reed of the piano key code shirt loses its elasticity, resulting in the phenomenon of poor contact of the piano key in the process of operation, and the switch of the piano key must be replaced at this time, and the exhaust fan can operate normally.

3. The power cord of the electric collapse motor is not in good contact, at this time it is necessary to re-weld the power cord of the motor, the motor starting capacitor is not in good contact, check the connection of the starting capacitor, at this time, you need to re-solder the starting capacitor, and connect or replace the starting capacitor.

If the exhaust fan is broken, it is necessary to check and solve the problem, the cause of the failure and the solution

1. The impeller and the diversion friction of the ventilation fan are damaged or the exhaust fan is faulty due to the lack of oil in the motor bearing of the ventilation fan, which causes non-lubrication, at this time, it is necessary to measure the opening size of the ventilation fan, and then purchase a ventilation fan of the same size according to this size and install it.

Generally speaking, if you use the exhaust fan for 3 years, you don't need to repair it again, one is that there is a lot of dust inside the exhaust fan, resulting in a decrease in the operation efficiency of the exhaust fan, the second is that the plastic material used in the general exhaust fan is easy to be brittle and broken after 3 years, and the possibility of damage again after maintenance is relatively large, and the third is that the lubricating oil inside the motor of the exhaust fan has been in the urban area, and the lubricating oil needs to be added again for lubricationIf there is exhaust fan bearing wear, or the eccentricity of the impeller of the exhaust fan, then the exhaust fan is prone to noise, and vibration, it is very easy for the motor to burn out, if you must repair, you can consider replacing the same model of the new motor, while replacing the centrifugal impeller, in this way, the exhaust fan can also be in the war for two years, static electromechanical technology can provide you with maintenance suggestions for exhaust fan products.

Remove him and take it to an ordinary electrical repair shop, or if you can't dismantle it, you can call a nearby repair shop to come to your door to fix it. If you have used it for too long, it is recommended to replace it with a new one.

1. Explanation of exhaust fan: exhaust fan is a kind of air conditioning appliance that drives the fan blade to rotate and drive the airflow by the motor to make indoor and outdoor air exchange. It is also known as ventilation fan, ventilation fan, etc.

The purpose of exhaust air is to remove dirty air from the room and regulate the temperature, humidity and feel. Exhaust fans are widely used in homes, public places and industrial plants.

2. The ventilation principle of the exhaust fan: the exhaust fan is a kind of air conditioning appliance that drives the fan blades to rotate and drive the airflow by the motor to exchange indoor and outdoor air. It is also known as ventilation fan, ventilation fan, etc.

The purpose of exhaust air is to remove dirty air from the room and regulate the temperature, humidity and feel. Exhaust fans are widely used in homes, public places and industrial plants.

3. The principle of installation and dismantling of the exhaust fan: the exhaust fan in the bathroom is very important and the installation position of the exhaust fan is generally very high, so the installation must pay attention to safety, and someone must supervise the site Please turn off the power supply and remove the exhaust fan panel first (the exhaust fan panel is generally connected by plastic buckle and steel wire spring buckle), unscrew the fixed wood screws at the four corners of the exhaust fan, gently remove the exhaust fan, unplug the power plug, remove the fastening ring and hose of the exhaust fan connecting hose, add a few drops of oil to the bearing after removing the dust with a brush, Then plug in the power supply test machine If it is normal, you can follow the steps of disassembly, otherwise, you can use the exhaust fan normally after installation and reset If you are sure that the exhaust fan is broken, then you can omit the steps of removing dust from the brush and adding oil to the bearing, buy the same model of exhaust fan, and check whether the connecting hose is damaged, and then, please follow the steps of disassembly, on the contrary, you can use the new exhaust fan normally after installing and resetting.

First of all, it is determined that the exhaust fan is broken or the switch is broken, the source.

If the switch is broken, you don't have to remove the ceiling, if the exhaust fan is broken, you must take off the ceiling, if the ceiling is that kind of PVC strip buckle, you must start to remove it from the side, if it is a 30x30 aluminum alloy buckle plate, it is much more convenient, it is best to have a multimeter, measure that the exhaust fan motor is burned, or the capacitor on it is broken, and then the wire is broken.
