What is the reason why the range hood trips when it is turned on with a loud noise?

The trip is likely to be a short circuit in the circuit, and it is recommended to check the circuit.

You can use a multimeter pen to check whether it is a trip caused by a short circuit in the circuit, if the test result is a short circuit. Carefully inspect the place where the range hood is in contact with the wires and do some insulation.

If it's not a trip caused by a short circuit, it's time to think about other things. It could be a problem with the hood itself. Recall whether you have disassembled the range hood, or whether the range hood has been used differently recently, and whether there have been some other minor faults.

If tripping occurs frequently, it is recommended to find a professional maintenance personnel to check and repair.

If it is a newly bought range hood, it is best to contact the seller and let the seller deal with the situation. For repairs or replacements, it is important to communicate with the merchant to effectively solve the problem. This also protects the interests of consumers.

1. If the automatic control fails, the indicator light will not light up. Most of these faults are due to lack of cleaning and maintenance, so that the gas sensor on the board surface is stained with oil, resulting in the sensor being hindered, in fact, at this time, you only need to remove the sensor, put the mesh cover into the detergent and clean it with a brush, if the gas head is dirty, you can wash it with anhydrous alcohol and put it back in place, troubleshooting.

2. When the motor can rotate, the noise is loud and the shell is very hot. This kind of obstacle is mostly caused by serious lack of oil or wear in the electric rotation, when repairing, first of all, remove the fan blade, pinch the rotor shaft end with water and shake it gently, if it is not loose, the feel is tight, it means that there is a serious lack of oil, if there is a loose phenomenon, the feel gap is large, it means that the wear is serious, and the new bearing should be replaced at this time.

3. If the smoke absorption effect is poor. If the installation point is too high from the stove, lower the installation point appropriately; If the seal fails to leak, replace the seal to make it tightly sealed; The activated carbon in the internal circulation fails, and the activated carbon is replaced; If the exhaust pipe is too long or the direction of the air outlet is not selected properly, the exhaust pipe should be shortened appropriately and the direction of the air outlet should be re-selected; If the voltage is too low, a voltage regulator should be configured if necessary; The suction channel is blocked by oil stains, and the oil stains are cleaned; If the pressure difference between indoor and outdoor is too large, open doors and windows appropriately to reduce the pressure difference between indoor and outdoor.

The reasons are diverse, 1. The fan installation is not suitable, and there is friction or collision when rotating, resulting in abnormal noise. 2. There is no reasonable maintenance during use, and each bearing part lacks lubricant and cannot play a lubricating role. 3. If there is a problem with the installation, the installation is not correct or the screws are relatively loose.

The wind is too strong, and the material of the smoke exhaust pipe is relatively soft, so it is easy to make noise when exhausting. There are a lot of oil stains on the range hood, and the machine does not work smoothly when it is started. How to deal with it:

1. If you find that it is a problem with the fan, you can remove the range hood and install it according to a reasonable installation method. 2. If the range hood has been rattling after starting, then the range hood can be disassembled and then carefully checked, it is very likely that the friction sound caused by the lack of oil in the bearing in the range hood, so you can add an appropriate amount of lubricating oil to the bearing, and then install the range hood to the original position. 3. After the range hood has been used for a long time, its position may have been shifted, and it may not be installed properly.

The range hood makes a noise and it may be that the screws that fix the range hood are loose, at this time we need to remove the range hood for reinstallation, tighten the screws that fix the range hood and then re-debug and install. 4. Replace the exhaust pipe, or turn on the low gear to reduce the air volume. 5. Clean the range hood in time, including the inside of the range hood.

There are several reasons for the sound of the range hood after it stops: 1. The sealing between the pipe and the flue is not done well, and there is air leakage that causes the range hood to still sound after it is stopped. 2. The sound of the power transformer causes the range hood to stop and there is still a sound.

3. The effect of the delay function causes the range hood to still sound after it stops. 4. The check valve is not installed, and the noise such as return air appears in the exhaust duct. Suggested workaround:

1. There are various decoration problems, sometimes when you decorate your kitchen, the pipe and flue of the range hood are not sealed, and there will be air leakage, resulting in abnormal noise. In this case, the interface should be resealed, you can do it yourself, such as Chundaguo feel troublesome, contact a professional maintenance master to come to repair. 2. If you turn off the range hood and pull out the socket stool at the same time, the sound of the range hood will disappear, then you can determine that the sound is from the core of the power transformer.

In this case, there is no special worry, it is the sound of the transformer caused by the inertia of the fan, and after a while it will automatically stop. 3. It is also possible that the delay function is working, that is, the fan is still rotating when the range hood is not energized, but it will disappear automatically after a while, and there is no need for special treatment. 4. If none of the above is correct, then check whether the check valve is installed, or the cover of the valve is opened, and the corresponding treatment can be made in this situation.

There are several reasons why the range hood keeps ringing: 1. The hood is loose, and it vibrates back and forth as soon as it works, causing it to ring all the time. 2. The exhaust outlet is blocked, and the oil smoke cannot get out, resulting in a constant sound. 3. Gas leakage and range hood alarm cause it to ring all the time.

This is normal. Generally, there will be a sound when the range hood starts, because it has to absorb oil. If the reason for the constant ringing is:

The range hood is not firmly installed, resulting in the noise emitted by the resonance between the motor and the fuselage during work; The problem of the check valve part is reversed or there is a foreign body resisting, resulting in the sound that the exhaust air can only flow out of the small gap; The smoke machine has not been washed for a long time, and the oil scale accumulated over the years causes the wind wheel to rotate unsteadily, and the sound of machine wear caused by the rotation offset center of gravity.

Expand: Matters that should be paid attention to in range hoods.

1. The power cord socket must use a reliable special socket and the plug must not be changed without authorization, in case of leakage grounding, a current circuit can be provided to avoid electric shock.

2. The power supply voltage and frequency used should be consistent with the product use requirements. The three-core power socket must be reliably grounded, and the distance between the power socket and the body should be greater than or equal to 1000 mm, and the grounding wire must not be overlapped on the water pipe and gas pipe.

3. The left and right sides of the installed range hood body should be kept horizontal, and the air outlet should be slightly lower when the air duct is installed to prevent oil backflow. And the distance to the body should be short, and the turns should be few (it is better to make only one turn).

4. During use, if there is abnormal noise, rotor does not rotate, smell, smoke, etc., the power supply should be cut off immediately for inspection and repair. If the electrical appliance fails, it must not be disassembled and assembled without authorization, and must be repaired by the maintenance department.

Dear, hello, I am very happy to serve you, what is the matter with the range hood tripping as soon as it starts, dear, for your specific inquiry, the reasons are as follows: range hood line leakage or short circuit. The range hood has been used for too long, causing the range hood itself to leak.

When the internal circuit is damp, it will undergo a grounding reaction, causing the switch to jump as soon as the switch is turned on. When this happens, the internal wiring can be replaced. Problems with electrical outlets.

Power socket issues require checking that the power socket is properly routed. Empty open fault. This kind of fault needs to find a professional maintenance master to repair and clear the fault faster.
