What is the reason why there is water on the main board of the household range hood line?

There is water on the main board of the household range hood line, it may be due to the steam water inhaled during the cooking process, if the whole range hood has no electricity, first check whether the power supply voltage of the range hood is normal? And is there an output on the circuit board of the range hood?

After power-on, the cause analysis and treatment cannot be started: the power cord is broken or the joint is desoldered, carefully find out the broken circuit or desoldering point, and re-weld it; If the on-off switch is broken or the contact contact is poor, check whether the circuit breaker is welded well, and replace it with a new product if the contact contact is poor;

The capacity of the starting capacitor of the motor is reduced or short-circuited or broken-circuited, which requires the replacement of the capacitor of the same specification to make the motor run; The variable speed coil is broken or short-circuited, and the variable speed coil is repaired or replaced with a new one; The bearing is damaged and the shaft is jammed, and the bearing must be replaced; Stator winding short circuit or connection wire break, stator winding repair or replacement of new products.

The main line of the household range hood is accompanied by water, what is the matter with the whole range hood running out of power? First of all, there is water vapor, and it is hung on the circuit board if it is not started, and there is no electricity, first of all, we must see if the power socket is good, and then the multimeter measures whether the motor is a good line, and there is no broken place to eliminate these problems will turn up?

In your case, it is typical that water ingress into the board causes the UMC phenomenon. The water of the circuit board must be cleaned, and the surface must be damaged to see if the original is damaged, and then the power test will be carried out if not.

There is no way to help you solve the problem here, and you can only find a professional master to help you check it before you know what the cause is.

Hello, dear, I'm glad I can answer for you. The reasons for the water output of the range hood are as follows: 1. If it is dripping water on a rainy day, it means that the smoke exhaust outlet has rainwater, and you can go to the roof of the building to see if the exit is aging and rotten. 2. The water pipe is discharged in the flue.

3. Check whether there is a problem with the exhaust pipe of the range hood, resulting in water in the range hood. 4. Whether it is the automatic cleaning function of the range smoke machine and the washing function of the weighing skin is faulty. 5. If there is water in the waste oil box, it is the hot steam that flows into the box after cooling during cooking.

<>1. Whether the potato stove has a power outage, wait for the power to be turned on before use. 2. Check whether the power plug is plugged in well, and plug the power plug back in before use. 3. Whether the power switch is turned on, some models of products have a main power switch, so the main power switch must be turned on before it can work.

4. Electric Kai dry machine thermal fuse.

If there is an open circuit, replace the motor with the same specification. 5. The connecting terminal in the control line.

Loose, locate the connection terminal that has been loosened, and plug it back in.

How to deal with water ingress into the main board of the range hood Hello dear, 1First of all, remove the motherboard with water, and then find the motherboard with traces of water ingress, this process must be carefully checked, if there is a missing place that has not been dealt with, and then put the motherboard back into the computer to use it will still have problems. 2.

We need to prepare high-purity alcohol or plate washing water, medical cotton swabs and absorbent cotton cloth, and then use absorbent cotton cloth to blot the water inlet part of the motherboard, taking care not to drag and scratch the circuit. 3.After the water is absorbed, we use a cotton swab dipped in alcohol or washing water to gently wipe back and forth on the water inlet area, if there is a corroded circuit on the motherboard, then the equipment will focus on the corroded part.

4.After wiping, we use a hair dryer or air gun to dry the motherboard that we have just wiped, and then wait for a while to install the motherboard back. Note:

When water enters the motherboard, do not use a hair dryer to dry it, because it is easy to blow water into the pins of the chip, which will speed up the corrosion of the motherboard. The first thing to do after the motherboard enters the water is to disconnect the power supply, and then deal with it in time. Hope it helps.

1. It may be that there is no electricity at home, just wait for the call; 2. If the plug is in poor contact with the socket, the plug and socket should be overhauled or replaced; 3. The fuse on the power board is broken, and the fuse must be replaced; 4. If the contact of the range hood switch is poor or damaged, it must be repaired and replaced, and the electrical connection wire or terminal in the electronic switch is loose and falls off, and the falling point can be found and reconnected and fastened; 5. If the power cord is broken or the interface is loose, the power cord must be replaced or the interface must be connected.

Expansion: daily maintenance of range hoods.

1. Crush the leftover soap used daily at home, add water and stir it into a paste, and then apply it to the place where there is more oil stain on the range hood, after a period of time, scrub it with a clean rag, and then apply a layer of soap paste, so that it can prevent oil stains and make the range hood bright as new.

2. The gap of the fan blade is small, and it is difficult to put your hand into it when cleaning. After scrubbing, you may wish to apply a layer of glue to the fan blades, and after a few months, remove the oil-stained glue sheet and reapply it, so that you can continue to use it again.

3. Although the cleaning of the oil storage box is not difficult, the anti-oil work must be done well, it is recommended to paste a layer of plastic wrap in the box, completely cover the box and slightly exceed the box surface, so that the Bu Ming oil smoke is adsorbed on the fresh-keeping code film, and then smoke it up after a period of time and replace it with a new one.

4. Every time you finish cooking, don't turn off the range hood immediately, let it continue to run for 1 minute, and pull out the residual oil smoke outdoors to achieve the purpose of fully eliminating oil smoke and reducing oil condensation.
