What should I do if the air conditioner motor does not start after power on?
The air conditioner motor does not start after being powered on. In most cases, this kind of fault is caused by an abnormality in the starting circuit of the motor. Of course, it may also be the power circuit and the motor windings are defective. Air conditioners, like refrigerators, freezers, etc., all use resistance phase-splitting to start operation. If the capacitor in the starting circuit is damaged or the phase-splitting resistance is damaged, the Air conditioner motor will not work properly, so check the starting circuit first during maintenance. If there is a fault, check the motor if there is no fault. It is very likely that a partial short circuit or open circuit occurs in the motor. Find a multimeter, and then use the R×1 block of the meter to measure the resistance value of each winding to judge.

What should I do if the speed of the air conditioner motor is slow and powerless?

If the air conditioner motor rotates slowly and is powerless after being powered on, you can make a simple judgment first to see if the light bulb in your home is dimmed. If it is dimmed, the voltage is too low. And the general situation is that the voltage is unstable and suddenly becomes low. It can be solved by installing a voltage stabilizer in your own home.
