The hood doesn t turn anymore and there is a humming sound

1.Use something to toggle to check the sensitivity, if it can't be rotated, the shaft is stuck, and the bearing needs to be replaced.

2.If the shaft moves, the capacitor is broken and the motor burns less.

3.For range hoods, short circuit of power cord or joint desoldering is the most likely reason why the range hood motor does not rotate, in such a situation, we must first carefully check that it is a short circuit, not connected and other problems, after checking, if there is a problem, replace the capacitor of the same specification to make the motor run.

4.If your range hood vibrates greatly, you have to consider its quality and internal motor problems, if you encounter this problem, we have to take some measures, if it is not well fixed, we will fix them with rubber and then readjust the spindle and maple leaf, so that this problem is almost solved.

5.Oil leakage is normal for range hoods, causing such a situation may be caused by improper installation, of course, this is simple to operate, as long as it is reinstalled to keep it at a certain angle, there is also a situation to pay attention to, that is, there is no regular cleaning, we should often clean the pipe inside the oil cup to avoid grease scale.

6.The poor effect of the range hood will also affect one of the reasons why the range hood motor does not rotate, if this situation occurs, we will have to make appropriate adjustments, replace the sealing strip to make it tightly sealed, and also properly open the doors and windows to reduce the pressure difference between indoor and outdoor, if necessary, you can configure a voltage regulator, and deal with the oil pollution in time when the suction path.

In the case of range hoods, it is more likely that the motor is stalled, that is, the motor rotor and the load (fan blades) of the motor are stuck, and the motor cannot be started.

It is also possible that the capacitor is broken, or the motor is broken, or the supply voltage is too low.

The reason why the range hood motor buzzes and does not turn:

1. There is a capacitor in the range hood, if it is damaged, it will affect the range hood.

2. It is also possible that there is a fault in the circuit, such as a short circuit in the line connecting the range hood, which will directly cause the motor to not work. You can check if there is a problem with the circuit and measure it through a multimeter.

3. There is another reason, many families usually do not pay attention to cleaning when using range hoods, and oil stains will accumulate more and more, which will wrap the motor, so that the motor can not operate normally, and this is also a frequent problem.

Solution: 1. If there is a problem with the capacitor, it needs to be replaced with a new one for normal operation. When replacing it, you need to pay attention to choosing the same specification, you can go directly to the brand service store for consultation.

2. If there is a fault in the circuit, you can see whether the fan blades of the range hood can operate normally. If it is not the problem of the capacitor, the internal circuit of the capacitor is faulty, and the circuit needs to be replaced and repaired.

3. If there are many oil stains on the range hood, you need to disassemble the range hood and clean it, and you should also pay attention to cleaning the stains of the range hood regularly, so as to make the use of the range hood better.

What's the deal with the range hood when it's not in use, sometimes it suddenly buzzes?

This is a normal imitation of muffle, and the hood will be a bit buzzing even when not in use. That's because the exhaust duct of the range hood is straight through the hood back to the roof, so there will be some echo at any time in the preparation or failure.

Reason: 1. Check whether the power supply line of the range hood is short-circuited or the joint is de-welded, resulting in the range hood not rotating and the phenomenon of humming, the solution to this situation is that it is recommended to carefully check that the power supply of the range hood is caused by a short circuit or the joint de-welding, and it is recommended to ask a professional maintenance master for testing and maintenance. 2. Check whether the bearing of the range hood is pasted by the oil, resulting in the situation that the range hood cannot rotate, if this is the case, check the reason why the bearing does not rotate, if it is the cause of the oil stain, it is recommended to clean the oil stain in time, or replace the new bearing.

3. If the bearing of the range hood is in a normal state of rotation, but the range hood still does not rotate, and there is a buzzing sound, it is recommended to check whether the capacitance of the range hood is damaged, and in this case, it is recommended to replace the capacitor of the same specification in time. 4. Check whether the internal motor of the range hood is damaged, if this is the case, it will also cause the range hood to have a buzzing sound and the range hood does not turn, the solution is that it is recommended to ask a professional maintenance master to check and repair, or replace the new motor.

Analysis of the reasons why the range hood only buzzes and does not turn: 1. It may be that the range hood at home has not been cleaned for too long, and it is too greasy to jam the fan or motor of the range hood. 2. It is also possible that the capacitance of the range hood is broken, causing the range hood to just hum and not turn the ruler.

The range hood only buzzes and does not turn, and it is recommended to deal with filial piety: 1. If the range hood at home has not been cleaned for a long time, there is too much oil pollution, which hinders the rotation of the range hood.

Check whether the power supply line of the range hood is short-circuited or the joint is de-welded, and it is recommended to ask a professional maintenance master for testing and maintenance; Check whether the bearing of the range hood is stuck with oil, clean the oil in time, or replace the bearing with a new one; Check whether the capacitance of the front unit of the oil smoke is damaged, and replace it with a new one of the same specification and clean the container; Check whether the internal motor of the range hood is damaged, and it is recommended to ask a professional maintenance master for inspection and maintenance.
