The range hood is used every day in daily life, especially in summer, if the range hood fails, then you will never want to cook by yourself, or simply go out to eat. However, eating out every day is still a bit unacceptable, and you still need to master several common troubleshooting methods. The following will share with you some common faults and maintenance methods.
1. The indicator light of the range hood does not light up
Solution: If the motor of the range hood turns and the light does not turn on, the bulb is usually burnt out, and the bulb needs to be replaced.
2. The smoke exhaust effect of the range hood is poor
Solution: Check whether the installation height of the range hood is too high, and adjust the height appropriately. Generally, the distance from the cooker is 65cm-75cm. If the direction of the smoke outlet is not selected correctly, there is a foreign object in front of it; the installation position must be changed to avoid obstacles. There is air leakage at the interface of the exhaust pipe; the interface must be sealed. The oil filter is too oily; it should be cleaned regularly.
3. Noise is generated when the motor is working
Solution: It may be that the impeller is not installed properly. If the noise caused by the improper installation, the impeller can be reinstalled. There may also be foreign objects entering the air duct, and the foreign objects should be removed to ensure that the air duct is clean.
4. The range hood produces vibration
Solution: Due to loose fixing screws, such as motor end cover screws, impeller center shaft fastening rivets, etc., the loose parts should be found, and the screws should be tightened or reinstalled; if the range hood is not installed horizontally to cause vibration, it needs to be leveled and hung firmly. The impeller is not installed properly or the impeller is deformed and damaged, loses its balance and causes vibration, and it is necessary to re-adjust and install the impeller.
5. The hood has oil leakage
Solution: The hood has not been cleaned for a long time, resulting in too much dirty oil in the oil box. It should be cleaned regularly; the hood body has oil leakage, and the filter screen and the whole machine of the hood should be cleaned regularly; the installation of the hood is uneven.
6. The range hood has no response
Liberation method:The power supply is not plugged in or has no power due to power problems, plug it in or wait for an incoming call; the plug and socket are in poor contact, check the plug, socket or replace it; the fuse on the power board is broken; the fuse must be replaced. Due to circuit problems, the switch of the range hood is in poor contact or damaged. It is necessary to overhaul and replace the electrical connecting wires or terminals in the electronic switch that are loose or fall off. You can find the point of falling off and reconnect and tighten. If the power cord is disconnected or the interface is loose, replace the power cord or connect the interface.
