〖Frequently Asked Questions〗
The range hood fails to start after being powered on
Cause analysis and treatment: The power cord is broken or the joint is desoldered. Carefully find the break point or desoldering point and re-solder it firmly. The on-off switch is open or the contacts are in poor contact. Check whether the circuit breaker is welded properly. If the contacts are in poor contact, replace it with a new one. The motor starting capacitor has a reduced capacity or short circuit or open circuit. In this case, it is necessary to replace the capacitor with the same specification to allow the motor to operate the speed change coil. If there is an open circuit or short circuit, repair the variable speed coil or replace it with a new one. If the bearing is damaged and the rotating shaft is stuck, the bearing must be replaced. If the stator winding is short-circuited or the connecting wire is broken, repair the stator winding or replace it with a new one.
Fault 2 of the range hood: There is abnormal sound or loud noise during operation
Cause analysis and treatment: Improper assembly causes the fan blade to loosen and hit the air guide frame to produce abnormal sound. Re-assemble and tighten the fan blade fasteners correctly. The motor bearings are severely worn and must be replaced with the same type of bearings. The motor assembly is poor. Correct the motor stator and rotor clearance to make it uniform. If there is axial movement, appropriate washers should be added to the unbalanced deformation of the fan blades. Correct the fan blades and adjust the movement and movement of the fan blades. The design of the statically balanced air outlet duct is unreasonable. The air outlet duct should have as few turns as possible, and the corners should have a large arc and a round shape.
Range hood failure 3: The range hood vibrates too much
Cause analysis and treatment The fixation is not firm or the installation is poor. Add rubber pads or foam plastics to fix it firmly. There are foreign objects on the blades and the internal scale is too thick. Remove it. Foreign objects and internal dirt on the blades. The main shaft and the blade sleeve are eccentric. Re-adjust the main shaft and the blade sleeve to make them concentric. The motor bearings are worn or the bearing holes are too large. Replace them with new bearings of the same specifications. The motor windings are partially short-circuited or open-circuited. Replace them. winding or motor.
Four oil leaks in the range hood failure
Cause analysis and treatment: Improper installation and insufficient elevation angle. Reinstall it to maintain a certain elevation angle so that the sucked oil can flow naturally and smoothly down the oil cup or add oil at the air outlet. A filter screen with a certain angle prevents oil droplets from dripping off under the action of surface tension. The sealing strip will become invalid over time. Add rubber or foam plastic strips to the sealing area to tighten the parts to improve the sealing level. If it is not cleaned regularly, it should Frequently remove the grease in the oil cup and clean the filters and pipes to avoid smoke and grease spillage.
Faulty range hood five: poor effect of extracting oil smoke
Cause analysis and treatment The installation point is too high from the stove, appropriately lower the installation point. The exhaust pipe is too long or the direction of the air outlet is improperly selected. Shorten the exhaust pipe appropriately. Re-select the direction of the air outlet when the sealing strip fails and leaks. Replace the sealing strip to make it tight. The internal circulation activated carbon fails. Replace the activated carbon. The indoor and outdoor pressure difference is too large. Open doors and windows appropriately to reduce the indoor and outdoor pressure difference. The voltage is too low. If necessary, configure a regulator to clean the air suction passage if it is blocked by oil.
