Here Ever Power introduces someHouseholdAir conditioner motorThe common faults and air-conditioning motor repair methods can eliminate the faults in advance and save repair time. If there are minor faults, we can also repair them by ourselves!
1. What should I do if the home air conditioner motor does not start after powering on?
In most cases, this kind of failure is caused by abnormalities in the starting circuit of the motor. Of course, it may also be caused by defective power circuits and motor windings.The motors of air conditioners and refrigerators and freezers use resistance split-phase starting operation. If the capacitor in the starting circuit is damaged or the split-phase resistance is damaged, the air conditioner motor will not work normally, so check whether the starting circuit occurs first during maintenance. Failure, if there is no failure, check the motor.It is very likely that there is a local short circuit or open circuit in the motor. Find a multimeter, and then use the R×1 block of the meter to measure the resistance of each winding to judge.
2. What should I do if the motor speed of the household air conditioner is slow and weak?
If the air conditioner motor rotates slowly and is weak after the power is turned on, you can make a simple judgment first to see if the light bulb in your home has dimmed. If it becomes dimmed, it is caused by the low voltage.Moreover, in general, the voltage is unstable and suddenly becomes low.You can install a voltage stabilizer in your own home.
3. The housing of the household air conditioner motor is live
It is more dangerous if the motor shell is electrified, and the motor leakage current is within 0.8mA to ensure personal safety.The main reason for leakage may be that a certain wire core in the motor touches the air conditioner motor housing, or the leakage between the stator and the housing caused by the burning of the electric group, and the other possibility is the electrification of the motor caused by damp.So try to keep the air conditioner motor in a ventilated and dry environment.The resistance can be measured with a shake meter. If the resistance value is lower than 2MΩ, the motor is damp, and it can be dried with a hair dryer when the power is cut off.
4. The temperature rise of the household air conditioner motor is intensified when it is running
The temperature of the motors of household appliances will rise during operation, and the maximum temperature can reach 70°C. If it is higher than 70°C, it is an abnormal phenomenon. Stop working as much as possible for inspection.Especially when the surface temperature of the housing rises sharply just after the motor is working, and there is a burning smell, it can be judged as a motor overheating failure, poor heat dissipation conditions of the motor, short circuit of the motor winding, and motor quality problems will all cause this phenomenon.It is mostly caused by the short circuit of the motor windings. The motor can be disassembled to replace the motor windings, which is not too troublesome, as long as the insulation treatment is done.
