How to solve the problem that the exhaust fan at the top of flue does not turn

1. Check whether the flue is blocked. The range hood is used too frequently, even exceeding the load of the flue. Let the property invite professionals to smoke, but the auxiliary flue must be kept and cannot be connected with the main flue, otherwise there will be smoke, and the lampblack at home is not easy to discharge, which is more likely to cause blockage.

2. The fan does not rotate or is damaged, deformed and aged. Pay attention to whether the fan at home works normally. If there is any abnormality, it should be repaired or replaced in time.
