Nipple drinker system small class explanation: Reasons and solutions for the motor not turning on Cheapest ventilation fan!

What are the reasons and solutions for the motor not turning on the Cheapest ventilation fan? Follow the editor of nipple drinker system to learn more about it!
1. The power cord of the motor is in poor contact. At this time, you only need to re-weld the power cord of the motor to eliminate the fault with confidence.
2. The connection of the starting capacitor of the motor is poor. Check the connection of the starting capacitor. At this time, you only need to re-weld the starting capacitor, and wire or replace the connection of the starting capacitor.

3. Test whether the voltage is normal. Another serious problem is that after the start button of the motor is pressed, the green light-emitting tube does not light up. Use a universal meter to measure whether the 12V power supply voltage is normal. If there is no 12V voltage, check whether the low-voltage rectifier filter circuit and related originals are damaged. If any components are damaged, the components should be damaged. Then check the 220V AC power supply. Whether it is connected, whether the automatic transmission of the key switch is damaged or the contact is poor. If there is no abnormality in the above inspections, the green light-emitting indicator tube should be removed, and the green light-emitting indicator tube should be inspected. If it is damaged, the green light-emitting indicator tube should be worse.
4. The switch reed of the key has lost its elasticity. Because the switch of the keyboard loses its elasticity, it causes poor contact during the operation of the keyboard. At this time, the switch of the keyboard needs to be replaced, and the Cheapest ventilation fan can operate normally.
The above is the nipple drinker system editor introducing the knowledge of Cheapest ventilation fan motors!
