The air conditioner compressor starts normally without exhaust pressureThere is no refrigerant in it, 1.5P is not connected to the indoor unitThe compressor current is only 1.7What's wrong with it?The refrigerant has been let out and used well last yearTurn off the air return valve, the exhaust valve does not have any pressure at all. Turn on the return valve. The vent valve can blow out the lighter slightly
1 dirty solution: try molt tube2. there is no refrigerant, there is no refrigerant, slightly unscrew the valve will know. If not, vacuum it, leak it, and add snow
Question: it should be the compressor slide stuck, the compressor is idling.No work is done to compress, only the motor is idle, so the current is very small at 1.7, and the natural pressure is smaller.Solution: you can tap the compressor back to the side (left), so that might be normal
You're not a problemI have more problems than others
Look, your description should be that you did not test the compressorThere are several possibilities:1 four valve leakageThe exhaust gas is directly absorbed by the low-pressure end2. the suction section is blockedWhen you return the gas, you feel a vacuum under the test3. compressor, motor, connecting rod device is damaged, the motor is running, the compression mechanism can not be executedThis is the trouble, can only change the press4. inversionIn addition to the 3 phase inversion, single-phase electricity can be reversed in certain cases5. special compressorThe scroll wheel has an intelligent scroll press with a bypass valve inside, and this condition can be described at a specific timeRecommendation: Test and measure the parameters of the compressor under welding
