A hood is a useful tool in your kitchen, the main function of the hood is to extract, suck and filter the steam from cooking, especially those that contain large amounts of fat, as well as moisture and odors. Sometimes, with the passage of time and continuous use, the performance of kitchen hoods is disrupted due to engine damage, blocked filters, etc. Like any other appliance in your home, the hood may require troubleshooting and repair after some time of use.
❇️ Input Power Problem ❇️
The hood's two plugs may be short-circuited or overloaded. This problem occurs when different electrical appliances, including the hood, are connected to the electricity with the help of a tee. At this point, you can test the plug to rule out the problem.
The easiest way to test is to plug another electrical device into the same outlet, if it doesn't have a problem, the problem is with the other part of your hood. But if the other device doesn't work when plugged in, you need to check your circuit breaker. You can get help from an electrician to solve the problem.
❇️ Fuse Sensor/ Flow Sensor ❇️
Sometimes the cause of the hood failure is the failure of the fuse protection sensor. In these cases, you can look for melted metal or discolored glass in the breaker box to find a blown fuse in your circuit box. A multimeter to check if the fuse has continuous electric current or not? use. If the multimeter shows the correct voltage, it means that the current is continuous; If not, the fuse is blown, in which case the fuse must be replaced.
❇️ defective switches ❇️
The hood control panel connects to the fan and lights, so it's important to make sure power is getting to the switches. You must use a multimeter to test the current. If you can't detect current, the device switch needs to be replaced.
❇️ Circuit control board problems
If your hood fan is not working, the circuit board may be faulty. In most cases, if the touch panel turns on and runs at any speed without the blower, you need to check the circuit board. You should look for melted or broken components on the circuit board to determine which part of the board is the problem. If your problem is not solved by replacing that part, contact experts to replace the circuit board.
❇️ User Control Page or Display ❇️
This problem is often misdiagnosed; Before replacing this part, check all defective parts. If the hood turns on or runs at different speeds when you press an unrelated button, the touch panel needs to be replaced. The control panel is connected to the hood lights, and if there is a problem with the control panel, the lighting system may also be damaged. To solve this problem, the part must be replaced. But before that, check the electrical connection system or whether the lamps are healthy.
❇️ Fan motor does not rotate;
If the board uses a switch to turn on the fan motor, you should test the fan switch for continuity using a multimeter or continuity tester to see if the fan switch allows power to flow to the motor.
Turn on the switch, this test should be done while the board is still unplugged. If the motor is powered by the control board, check if the fan motor is receiving 120 volts. If not, replace the motor.
❇️ Fan loose and sounds ❇️
To keep everything firmly in place, tighten the screws on your fan motor and check that the fan blade is firmly in place and that it can spin properly. To inspect the fan blades, open the blower's plastic housing and make sure your fan blades spin smoothly. If something clogs the blades, your blower may become damaged and noisy after a while.
But if you smell a strong chemical burn coming from the motor, turn off your hood and unplug it, and immediately Call hood repair experts to fix the problem in the shortest possible time.
