If the upstairs is also a victim, go up one floor to continue the examination. If you don't find out thoroughly, you'll have a big head.
There is also a need to check the entry and exit channels of the exhaust fan for the possibility of water seepage.
If it is confirmed that the power supply line of the exhaust fan has been disconnected, the rotation of the exhaust fan is a natural rotation, that is, the rotation caused by airflow.
Make two exhaust fans into one circuit, and use one switch to OK.
This situation is generally a capacitance problem, and it is good to spend a few dollars to buy an exhaust fan capacitor and replace it in the repair department. I found one from the unit's electrician class, and I just changed it. It's been running for two years now, and it's making a good profit. FYI!
Can be wiped with flour.
1. There are generally two types of kitchen ventilation fans: one-way and two-way; The one-way can effectively discharge all kinds of harmful gases in the room, and the two-way one can not only exhaust the gas, but also pump in fresh air. >>>More
Of course, the range hood is good, the fan blows the fumes everywhere, and it should not have a purification effect, and it will also have an impact on the neighbors.
