The wiring diagram of the four-wire motor shows that two wires are connected to the capacitor and the other two wires are connected to the fast and slow keys. The wiring diagram of the five-wire motor shows that two wires are connected to the capacitor, two wires are connected to the fast and slow gears, and the remaining blue wires are connected to the male ***0 wire.
Measure with a multimeter, and connect a capacitor between the two wires with the largest resistance; Probably black and yellow, but I'm not sure. Speed adjustment must be made by using two wires with the least resistance.
Extended data range hood, also called range hood, is a kind of kitchen appliance to purify the kitchen environment. Installed above the kitchen stove, it can quickly pump away the waste burned by the stove and the oil fume harmful to human body generated in the cooking process, and discharge it outdoors, thus reducing pollution, purifying the air, and having anti-virus and anti-explosion functions.
The range hood needs to be cleaned regularly, and simple cleaning can't remove oil stains. To clean the range hood, professional cleaning agents must be used.
