The impact of commercial refrigeration compressor (2)
4. Starter damage The starter is damaged, causing the compressor start winding circuit to be unable to be connected at the moment of power-on, and there is no current in the start winding, and the compressor cannot be formed Rotating magnetic field, so it doesn't work. Features: The door light is on, the compressor does not run, but it sounds clicks , and the measured commercial refrigeration current is 6A, x, 12A. The measured PTC starting resistance is far from the marked value. The heavy hammer starter measures the forward and inverted resistance, and it cannot change well between on and off. Repair method: replace the starter of the same model.
5. Compressor coil is open and the compressor is running or starting to bypass the open circuit, causing the compressor to lose one magnetic field and fail to operate. Features: The door light is on, the compressor does not run, and some also make a click sound. Test the compressor inlet line with 220V voltage, unplug the compressor power supply and compressor accessories, measure the resistance between the three terminals of the compressor, there are two The resistance between the two terminals is infinite. Repair method: replace the compressor of the same model.
6. commercial refrigeration Compressor jammed cylinder or pumping shaft compressor's mechanical parts are stuck and do not move, so that the compressor does not operate. Features: door lights are on, the compressor does not operate, most of them make buzzing or clicking , Measure that the compressor inlet has a voltage of 220V, and the resistance between the measured compressor terminals is normal. Maintenance method: Replace the compressor of the same model: You can also try to repair it by vibration method, capacitor activation method, voltage activation method, and reversal method.
7. commercial refrigeration The failure rate of the power cord is very low. If the power cord is broken, the compressor will not be able to operate without voltage. Features: The door light is not on, the compressor does not operate, and does not make any noise. There is no AC 220V voltage in the commercial refrigeration line.
