What is the reason why the compressor is not working
Check whether the power supply and compressor input voltage meet the standard requirements (187V ~ 242V), and whether the external power supply and compressor input voltage with a multimeter AC gear are within this range. If not, measures should be taken to adjust to the normal range. within.
Reason 2: The ambient temperature is too low①When the ambient temperature is too low (1～10℃), if the refrigerator is in manual compensation mode, the compensation switch needs to be turned on at this time. If the magnetic temperature compensation switch, you need to check whether the magnetic switch is normal: because the ambient temperature is too low, especially for For refrigerators with dual-temperature single-control refrigerators, as long as the compressor works for a short time, the refrigerator compartment reaches the predetermined temperature (1～10℃). At the same time, due to the low ambient temperature, the temperature of the refrigerator compartment rises slowly or does not rise, and the compressor is long The time does not work, the shutdown time is too long, and the temperature of the freezer compartment is too high, not reaching below -18°C.
②When the ambient temperature is lower than 0℃, you should stop using the refrigerator: because when the ambient temperature is lower than 0℃, the compressor oil will thicken and the lubrication performance will become worse; at the same time, the condensing pressure will become lower and the refrigerant will not flow into the evaporator. If you continue to use the refrigerator at times, it will not work normally and may cause damage to the compressor.
Reason 3: Whether the thermostat or main control board is normalâ‘ First check whether the thermostat is in the "0" gear, if it is not in this position, then check whether the thermostat is normal: adjust the thermostat gear to the strong cold gear when the power is on (if there is no strong cold gear, adjust Go to level 7), if the temperature sensor is in the box, you can also use a hot towel to heat the temperature sensor sensor to observe whether the compressor is running. If the compressor does not start, the thermostat may be faulty. At this time, you can cut off the power and remove the thermostat. Use a multimeter to measure whether the power contact and the compressor input contact are connected (resistance value is zero, according to the thermostat model). , Measure the corresponding contact on the parameter plate). If it is connected, check whether the temperature sensor tube of the thermostat is broken, cracked, or leaked. If so, the thermostat needs to be replaced.
â‘¡For refrigerators with electronic control systems, when the power is on, use a multimeter to measure whether the input voltage and output voltage of the main control board are normal. Does the display show that the compressor is working? Are the sensors normal? Is the contact of the connectors normal? If the voltage at the input terminal is normal and there is no voltage at the output terminal, it means that the main control board is faulty.
Reason 4: PTC starter failureUse a multimeter to measure whether the resistance at both ends of the PTC starter running jack and the start jack is normal (the normal resistance is between 16 and 50 ohms under normal conditions). If infinity or 0, the PTC starter is damaged and should be replaced .
Use an ammeter to measure whether the compressor's starting and operating current is normal (the starting current is generally about 5-8 times the operating current). If the current is normal and the overload protector operates, the overload protector fails and should be replaced. Otherwise, the compressor is malfunctioning.
Reason 6: Whether the compressor connection point is in good contactCheck how the compressor PTC start protector is plugged in, and plug it in again for a power test.
Reason seven: internal failure of the compressorIf the test compressor accessories are normal, but the compressor still cannot be started, and the overload protector operates (the measured start current is too large at this time), it is determined that the compressor is stuck in the cylinder or the compressor is holding the shaft, and the compressor needs to be replaced.
