There is a problem with the motor windings or insulation. When testing, you can use a multimeter to measure the resistance between the three terminals of the compressor, and the household air conditioner is generally a single-phase motor, and the terminal has a common end C, a running end R, and a starting end S. The resistance between the two terminals is mostly a few ohms, and rs=cr+cs.

Measure the insulation resistance of each terminal to the shell, which should be in the meaghm level.

The second is that there is a problem with the rotation of the motor.

There is a problem with the rotation of the compressor, when the compressor is powered, you can only hear the humming sound, this may be the compressor stuck, you can try to increase the starting torque with a larger capacitor, or connect the capacitor to the running end to make the compressor reverse. If you can't do it, you can only change the compressor.

It is not recommended to repair, the maintenance cost is large, and it cannot be guaranteed in the later stage.

Maintenance method for failure of air compressor pressure switch; Check if the switch has power: Use a tool such as a voltmeter or pen to test whether the switch is powered on, if there is no power, you need to check whether the power supply is faulty. Check whether the internal structure of the switch is faulty

Disassemble the switch and check whether the internal structure of the switch is damaged or in poor contact, and the faulty parts need to be replaced or repaired. Check whether the pipeline is blocked: Check whether the air compressor inlet pipeline, compression pipeline and exhaust pipe are blocked.

The pressure switch is mainly used in the air compressor to adjust the start and stop state of the air compressor, and to stop the air compressor and rest by adjusting the pressure in the air tank, which has a maintenance effect on the machine. When debugging in the air compressor factory, adjust to the specified pressure according to the customer's needs, and then set a pressure difference. For example, the compressor starts to start, pumping air to the gas tank, when the pressure is 10kg, the air compressor stops or unloads, and when the pressure reaches 7kg, the air compressor starts again, there is a pressure difference between them.

I wish you a happy life! Hope mine is helpful to you ha.

Will the switch fail if the sensor fixing wire is loose?

Kissing will cause the sensor to tremble and be unstable. Loose sensor wires should not cause the switch to malfunction. Failure of a switch can be caused by a more complex mechanical or electrical problem that requires specific inspection and repair.

If you want the air compressor to be as new, use it for a long time to see the following summary:

1. After 500 hours of use of the new machine, it is necessary to replace the oil grid and the special oil for the screw machine;

2. Then every 3000 hours, replace the maintenance consumables: oil and gas separator, oil grid, style, oil.

3. Pay attention to the tightness of the belt, the oil level, the display status on the display panel, check the temperature, noise, etc.

4. The machine should be selected in a well-ventilated, well-lit, dry, clean air and less dusty place.

5. After the machine has been running for a period of time, it is necessary to check the safety valve, thermostat, solenoid valve, radiator and other accessories that are easy to cause the machine to fail, and register it and deal with it in time.

Precautions] 1. Maintenance consumables should be original**, remember not to be cheap. If you use poor quality consumables, it may cause major failures such as machine head jamming.

2. When turning on the machine, you should check whether the oil level, belt tightness, and other accessories are normal.

3. If the machine automatically stops due to no-load operation exceeding the set time, inspection or maintenance work is absolutely not allowed at this time, and the air compressor will resume operation at any time, and the power supply must be cut off first for mechanical inspection.

4. The replacement of maintenance consumables should be operated by professionals, otherwise improper operation may lead to machine failure.

5. Don't be greedy and cheap to buy low-quality oil, tens of thousands of yuan of machine head can be much more expensive than engine oil.

6. The machine password is generally kept by the first businessman, the purpose is to prevent others from operating randomly and causing the air compressor to malfunction.
