1. the most common reason for the problem of air conditioners is poor contact. This is not a big problem. We can solve it in our daily life. The best way is to use a multimeter to measure the main switch, to see if the resistance is normal, if the resistance is too large or too small, there will be problems. If it is resistance, please repair or replace a suitable resistor.
2. air conditioner fan problem is another reason: the motor in the air conditioner and the screw of the fan blade connection is loose. For the solution of this problem, the small editor does not recommend that everyone go to the maintenance shop to repair it. We can solve the problem. We disassemble the screws outside the air conditioner and put the inside fan leaf. Screw and motor tightening is fine, but in maintenance, remember to cut off the power supply and pay attention to personal safety.
