There are many reasons why the range hood can't pump oil. Let's look at some common situations and solutions:
1. Pipe blockage of range hood: If the exhaust pipe is blocked by oil fume or other substances, the range hood will not be able to pump oil. At this time, you can remove the smoke outlet to clean the pipeline, or use a professional cleaner to clean it.
2. The exhaust pipe is too long: if the exhaust pipe is too long or bent, it will hinder the flow of smoke, resulting in the hood being unable to pump oil. At this time, a shorter smoke exhaust pipe can be replaced or a smoke exhaust port can be added.
3. Insufficient ventilation: Insufficient ventilation will affect the effect of the range hood. You can check the fan speed or replace the high-powered fan.
4. Filter pollution of range hood: If the filter of range hood is not cleaned or replaced for a long time, the smoke exhaust effect will be reduced. At this time, you can clean or replace the filter screen of the range hood.
5. The chimney is not smooth: If the chimney is not smooth, the range hood will not pump oil. At this time, the chimney can be cleaned or replaced with a chimney with a suitable diameter.
To sum up, there are many reasons why the range hood can't pump oil, which need us to deal with according to the specific situation. At ordinary times, attention should be paid to cleaning the range hood and smoke exhaust pipeline regularly to ensure their normal use. At the same time, we should also pay attention to choosing the range hood that suits us. You can't buy blindly according to price or other factors, but also pay attention to its performance and other indicators.
