Generally speaking, you will use the range hood as long as you cook at home, but if you use the range hood for a long time without cleaning it in time, it may happen that the range hood motor does not turn, then the range hood What if the motor doesn't turn?
Reasons for range hood motor not turning
1. The motor power of the range hood is not very large, and the probability of burning is usually small; if it can be concluded that the capacitor in the range hood is normal, the most likely thing is that the range hood has been used for too long, and the The motor rotor (bearing) is greasy.
2. The motor does not rotate and there is a humming sound, usually because the capacitance of the capacitor is reduced or short-circuited, which causes the motor to not start normally; you can first look at the appearance of the capacitor. If there are burn marks on the appearance, it means that the capacitor is broken and replace it. The new capacitor of the same type can eliminate the fault. (When replacing the capacitor, it is important to replace it with the same type. If there is no same type, you must be optimistic about its withstand voltage value. The withstand voltage value of the new capacitor must be higher than the original one. , only high but not low, if the withstand voltage value is low, the capacitor will not only be unusable, but also too small, it can burst! The capacity of the new capacitor should not be too small, and the motor will not start normally if it is too small.) The capacitor capacity is small in The appearance is invisible, as long as a new capacitor of the same type is directly replaced to determine whether the capacity of the capacitor is too small.
3. If you turn the fan blade of the motor, the fan blade rotates very lightly, which means that it is not smooth; finally think about the fault of the motor (the motor can be used for 8 years), the motor is hot. Moreover, the motor only rotates for a short time It's tricky! Explain that the coil in the motor is formed by inter-turn short circuit, the motor is broken, and you can only buy a new one.
4. If the motor rotor of the range hood is greasy, it will also cause the motor to fail to change normally, causing the motor to heat up and eventually burn down. You can gently turn the fan blade of the motor with your hand. If the fan blade rotates very slowly, it means that the smoothness is not good. You can turn on the motor, drop some lubricating oil on the shaft, and turn the fan blade of the motor a few more times until The motor's bearings turn briskly and stop.
