Reasons for the buzzing of the blower: 1. There is foreign matter in the blower: this happens only when the air-conditioning filter element is behind the blower, that is, if other foreign matters such as leaves and branches enter the blower, abnormal noise will occur. The solution is to disassemble the blower and take out the foreign objects, and the abnormal noise will disappear. 2. Lack of lubrication of the blower bearing: just add lubricating oil to the place of the blower bearing. If the bearing is severely worn and the abnormal noise is caused, the blower needs to be replaced, because nowadays, few people help with repairs, all of which are replacement parts. .
