Refrigerator just bought half a year, set the temperature after the start does not work, compressor operating voltage is how much? Can I measure the compressor lead voltage and determine whether the compressor is normal according to the measured compressor voltage?I'll do it myself. Does the refrigerator compressor have a protection? I often hear people say jump protection. How can I detect jump protection?
The power used by a refrigerator should be 220 volts, 50 Hz single-phase AC power supply, normal operation, the voltage fluctuation allowed between 187 to 242 volts, if large fluctuations or fluctuated, will affect the normal work of the compressor, the compressor will even burn. If the voltage is too high, the motor coil will be burned out due to too much current; the voltage is too low, which will make the compressor start difficult, cause frequent startup and burn the motor.
For domestic compressors, the operating voltage is: 220V 50HZ.Domestic exports and foreign models are mostly 110V 60HZ.You cannot determine the compressor voltage. Because you measured the voltage you entered.To see the operating voltage of the refrigerator compressor, please look at the instructions of this machine.
The refrigerator working voltage of 220V, the general voltage can work normally start at 198V-242V, you can check the power supply voltage of the compressor ports, also not the refrigerator power immediately after the electricity, at least 3-5 minutes before re energized operation, otherwise the compressor over-current protector action to cut off the power supply, protection of compressor.
According to you, the refrigerator compressor operating voltage is 220V, you can measure the compressor input wire voltage to determine whether it is normal. Press the normal startup, low voltage, voltage input, immediately resumed, press start is not normal voltage underground lot, a few seconds, until the start protector is disconnected, the voltage is back to normal, this failure is usually press card cylinder, or starting capacitor is broken; [some press did not start capacitance]
