Range Hood Maintenance and Repairation
Maintenance:
Daily use of the kitchen hood may, in the course if you come across hood voice and excessive vibration, fumes and spare drop of oil, oil spill situation. We have deliberately give consumers introduce some basic knowledge of the use of maintenance:
1, hood installation height must be appropriate, not only can guarantee not meet, but also ensures that the effect of fume.
2, in order to avoid the hood voice or excessive vibration, drop of oil, oil spills from happening, we have carried out on the hood should be cleaned regularly to prevent motor, turbine, and the inner surface of the hood too viscous oil.
3, when the use of hoods to maintain air circulation inside the kitchen, so that the air can prevent the formation of negative pressure inside the kitchen, the ability to ensure suction hood.
4, the consumer is best not to disassemble for cleaning hood, if not installed because the motor can not be guaranteed smoke effects, and will increase the noise; best to allow manufacturers of professional cleaning.

Oil Cigarette
The kitchen has a lot Hoods with oil on both boxes, full of drained oil, the oil box is very sticky, difficult to clean. Jie Xiao Bian below give you food out of a brilliant idea:
1 Put the clean oil box first and then put some water safety in the hood, so that oil droplets in the water.
2 win between other fast full mouth of an inverted basin, "grunt" look, the oil on the whole out.
3 and then a little detergent scouring pad on the oil box outside a rub, then washed with water an oil box is clean and agile.
Misunderstanding a power greater the effect will be better smoke fumes
Promoters will often take the power to do the article , saying that the greater the power , the better the effect of smoke fumes , which is a big misunderstanding. In fact power and smoke fumes are not necessarily linked , if a range hood just power, and turbo rough, motor manufacturing , but related , cavity manufacturing quality is very poor , are often just dry power, but can not reach a good effect.
Myth panel material is irrelevant
About the panel material, promoters could " deliberately forget" does not mention , or speak directly to a certain alloys term flicker consumers . In fact, the hood of the material is very important , imagine, a range hood, every day of exposure to various fumes, spices and other acid corrosion in the short term may not be seen, but after six months or a year , such as fading occurs , oil smoke and other issues. If corrosion to the wires, it will cause electrical short circuit , burning motor accident. In fact, to test material is also very simple , the best domestic materials are generally imported M-Cr stainless steel material , looks fine texture. This material anti-oxidation, anti- corrosion and will heal rub lighter. To identify such material differences with the general alloy material , you only need to try to direct the magnet can suck on , then certainly for the general poor quality alloy or iron-based , is not able to suck on a stainless steel material .
Myth cavity design unimportant
The importance hood cavity design can not be ignored , on the one hand to do as much as possible a seamless , easy to clean , but also to protect the circuit , so that various lines in this highly corrosive fumes under conditions to work properly, do not corrosion. And not just within the cavity of the cavity seamless seamless design , but also to do with the little plane parallel to the stove can also be seamless , while the oil network and cavity binding site has to be " invisible seamless " For example, to set up anti-oil wall , etc., so do not stay clean is really dead .
Myth has free washable functions can free washable
Absolutely free washable hood is not possible, a range hood with a year later , it must be washable , otherwise the turbo and smoke chamber attachment , it will seriously affect the smoke fumes . Therefore, a range hood is not unlimited "free washable" , but more should be designed as a " washable " , a year later , he could remove the oil network at home , turbine cleaning , so is really easy to clean.
Repairation:
Fault 1: can not start after power
Cause Analysis and Treatment : The power cord or connector disconnection Desoldering, carefully identify the trip point or sealing off point , re- weld ; -off switch contacts open or poor contact , check whether the circuit breaker at the weld , if contact is bad incumbent New ; motor start capacitor capacity is reduced or short circuit, which should be replaced with the specifications to make the motor run capacitor ; variable coil open or short circuit , variable speed coil repair or replace new ; bearing damage while stuck shaft, must be replaced bearing ; stator windings shorted or cable disconnection , repair or replacement of the stator windings new .
Failure II : Operation abnormal sound or noise
Cause Analysis and Treatment : improper assembly loose and hit the fan air guide box produce abnormal sounds, re- fitted correctly , tighten the blades stapled ; motor bearings badly worn and must be replaced with models bearing ; motor assembly is bad, corrected motor stator and rotor clearance to make it uniform , such as a traverse axis , should be added to the appropriate gasket ; blade deformation imbalance correction blades , adjusting the blades dynamic and static balance ; outlet air duct design is unreasonable . As little as possible out of the wind pipe bend , bend to radians large and rounded.
Fault Three: Hood excessive vibration
Cause Analysis and Treatment : stationary solid or poor installation , plus rubber mat or foam , fixed solid ; leaves a foreign body , the internal fouling too thick. Clear leaves on a foreign and internal dirty dirt ; eccentric shaft and blade sleeve , re-adjust the spindle and blade sleeve make concentric ; motor bearing wear or bearing hole is too large, replace with the specifications of the new bearings ; partially shorted motor windings or broken , replace or motor windings .
Fault IV: oil spills
Cause Analysis and Treatment : improper installation , insufficient elevation , reinstall , to keep a certain elevation , so suck out oil natural smooth flow oil cup ; or at the outlet of the filter and has added a certain angle, so that the oil droplets on the surface not under tension drops down ; seal failure falling in seal rubber or foam padded bar , pressed parts, raise the level of sealing ; does not regularly cleaned , you should always remove oil and grease cup each filter cleaning networks and pipelines, avoid smoke , grease spill.
Failure Friday : poor fume
Cause analysis and treatment : Install point from the stove too high , due to lower mounting points ; exhaust outlet pipe is too long or improper direction selection , appropriate to shorten the exhaust pipe , re-select the direction of the outlet ; seal failure leak, replace the seal so tightly sealed ; internally circulating carbon failure , the replacement of activated carbon ; interior pressure is too large , due to open doors, windows, interior and exterior pressure decreases ; voltage is too low , if necessary, to configure the regulator ; suction air passage blocked by oil , cleaning oil.
Fault six ; key switch failure
Cause Analysis and Treatment : If you press the key switch to lock , the file can not be pressed to start the motor , the common circuit connection , identify and re-weld ; such as where a file press the motor can not run , another file is normal, show only contacts that file control sub-file is damaged or broken off connections , contacts and connections should be repaired ; such as pressing keys switch the motor to run , not lock the keys after the release , the main switch is conductive and conductive spring deformation sheet exposure is not on, or switch spring displacement or loss, spring should be adjusted or replaced with new switches ; such as pressing keys switch two gears are locked , indicating that the interlock spring is compressional deformation , displacement, repair interlock spring should be adjusted .
Fault Seven: Hood affect cooking fire source heat
Cause and analysis process : Select exhaust volume is too large , causing heat waste , extending the heating time necessary to appropriately select the amount of exhaust ; hood mounted too low, should increase the range hood height.
Fault eight : hood is heavily stained
Cause analysis and treatment : no timely cleaning range hoods, range hoods should be wiped clean ; did not air duct cleaning, power off, open the cover and remove the baffle and filter, cleaned and installed .
Failure nine : touch switch not working
Causes Remedy: Replace button / control assembly plate.
1, hood installation height must be appropriate, not only can guarantee not meet, but also ensures that the effect of fume.
2, in order to avoid the hood voice or excessive vibration, drop of oil, oil spills from happening, we have carried out on the hood should be cleaned regularly to prevent motor, turbine, and the inner surface of the hood too viscous oil.
3, when the use of hoods to maintain air circulation inside the kitchen, so that the air can prevent the formation of negative pressure inside the kitchen, the ability to ensure suction hood.
4, the consumer is best not to disassemble for cleaning hood, if not installed because the motor can not be guaranteed smoke effects, and will increase the noise; best to allow manufacturers of professional cleaning.
