It may be on the back of the circuit board, or on the lid you removed.
What was it connected to?
Insurance claim for flood?
You could give more details on what it was. Looks like moisture damage any way with the mold in the bottom of the box.
It a circuit board for an extractor hood .it got damaged from water and at the moment I don’t have it to search for the model number.i want to order one soon but I don’t have the information
Bingo! A Google lens search of the image leads us to (surprisingly)
OK lets start with maker of the extraction hood. Was that the OEM control board or after market add-on. If you get those you might try a AI search for the board.
The maker is Angelo po .and that circuit board control the on/off switch,the light under the hood
I went to that thread and dug through it. Got a lot of page not available from the hardware list. If from aliexpress it may not be available anymore.
Oh ok it’s very stressful right now because I really need it

Consider there may be water damage to other electrical parts as well (rust, intermittent shorts, etc), and whether an entire replacement rather than repair is more cost effective.
Insurance claim? They would most likely write it off and replace it. If they go the repair route, ask (in writing) how long the repair warranty will last. That will often change their mind as the risk of consequential failure is quite high from dirty water damage.
I have seen many similar boards when I worked as an insurance assessor (in another career) and the first instinct was an instant write-off. Cash settlement time and junk it. Replace the board and you may only get a few weeks of operation before the unit starts to have other problems. A full regut and rebuild is uneconomical to repair, on a parts and labor aspect.
Scrap metal value from the stainless steel components may be used to offset replacement unit cost
What is the serial number and model number for that board?
Ok thanks.i will check it out
The manufacturer service department should be able to tell you. If you post a picture of the serial number sticker of the actual extractor fan, that would help, but I suspect you are not in the repair industry so out of your depth, otherwise you would not be asking these questions here in the HomeAssistant forums.
Call your insurance company if you have water damage cover. If you don’t, call a qualified appliance serviceman to look at what other parts have been affected.
At the risk of raising a heightened risk of electrocution and fire, removing the circuit board from the box, dipping the whole lot in methylated spirits and then carefully brushing the board as much as possible with a small paint brush dipped in methylated spirits, cleaning out the box, and then copious drying with a blast of compressed air might get get you going for a few hours, depending on how long the unit was underwater. The amount of corrosion on the underside of the circuit board (you haven’t posted that photo) will be a guide to that. Please check what the board was connected to, and inside the connectors which often will have corrosion and produce intermittent connections which raise the risk of fire. A battery powered smoke alarm should be fitted inside the chimney, just to be an early warning - the battery will outlast the life of the parts you have temporarily cleaned to get you going. This is extremely risky, but will sometimes get you going for a short period.
These model numbers will be required by the manufacturer’s spare parts division to get you the correct circuit board. Be aware that there may be other parts you will also need to replace, such as wiring looms, fan motors, loghr sockets, lamps, and switch assemblies to make sure the installation remains safe.
How about inside the ceiling where the water leaked? Any residual damage? Smell? Vermin infestation? Are the ceiling support mechanisms damaged with risk of collapse? How about what the extractor hood was fastened to?
That is the information on the fan for the extractor
Zooming in on your photo, I see rust and stain spots that alarm me. Junk the unit as a fan forced fire blowing into your ceiling space is not going to result in anything less than the loss of your entire premises. Once the small spark starts, the fan forced flow of lots of oxygen is just going to make it grow alarmingly.
Seen video of the recent Hong Kong apartment fires? Yes, similar.
Your fan motor may also have water ingress and should be megger checked for insulation breakdown. Any dried debris on windings will result in enhanced heat breakdown and shortened life. Not all motors have a fusible link built in. Often the part that melts the first provides the electrical interruption.
Check the lamps. Are the sockets corroded? Even a little? The reduced contact area will result in heat buildup in the remaining electrical contact spots. Any dried debris on the globes will raise the internal heat and reduce globe life.
Did I say heat? Sorry, I meant fire.
Don’t take the risk.
Do you have insurance cover for motor fusion? Water damage? Business interruption? Most importantly, loss of premises due to fire from unqualified electrical repairs? Yes, people like me will dig through the ashes to find the root cause, with lots of photos and carefully worded report, sometimes for the client, the insurer, and sadly, sometimes for the coroners court as well. Their image search may lead to here as well. Why risk your life?
Please let us know how you went and what the results were.
