What s wrong with the Meiling refrigerator compressor not starting?

Dear Meiling users, hello!

If the compressor starter and capacitors are fine, it is a compressor jam and needs to be replaced.

If you look at the temperature zone range of the manual, if you have a single temperature zone, it will not be activated in winter.

The compressor does not start when the refrigerator is powered on, but a humming sound can be heard inside the refrigerator case. In general, the causes of the fault and the troubleshooting methods are as follows:

1.If the power supply voltage is too low to measure the power supply voltage, compared with the rated voltage, if the measured voltage value is less than 85% of the rated voltage, it should be connected to the refrigerator voltage regulator, so that the power supply voltage of the refrigerator reaches the rated voltage.

2.Check the connecting wires of the thermostat when the thermostat is broken, if the broken wire or virtual welding fault is ruled out, but the compressor cannot be started, try to short-circuit the terminal of the thermostat. If the compressor can run, it means that the thermostat is damaged, and the fault can be eliminated by replacing the thermostat; If the compressor is still not running at this time, there may be a problem with the compressor and the compressor should be replaced to eliminate the fault.

3.The starting relay coil is open or the contacts are poorly contacted. Clean the relay contacts, then polish with fine sandpaper and adjust the rating of the relay appropriately, if the fault cannot be eliminated, the relay should be replaced.

4.The motor starting winding is broken to measure the resistance of the motor starting winding, to judge whether the starting winding is broken, if the starting winding is broken, the starting winding coil should be rewound.

5.If the defroster is damaged or the power-saving switch is damaged, check the defroster or power-saving switch, and if it is damaged, replace the defroster or power-saving switch.

6.If the capacitor is damaged, check whether the capacitor is leaking or open, if it is damaged, the capacitor should be replaced.

7.The power cord is disconnectedCheck the power plug and its power cord, and replace the power plug or power cord after determining that the plug is damaged or the power cord is broken.

8.Overload protection relay open circuit check the overload protection relay, and replace the overload protection relay after finding that the overload protection relay is open. If the defrost timer is damaged or in the defrost cycle, repair or replace the defrost timer, if it is in the defrost cycle, the compressor can work normally after the defrosting is over.

9.If the defrost timer is damaged or in the defrost cycle, repair or replace the defrost timer, if it is in the defrost cycle, the compressor can work normally after the defrosting is over.

10.Poor lubrication of the compressorCheck the lubrication parts of the compressor, and add lubricating oil when it is found that there is a shortage of oil. Refrigeration system too much refrigerantCheck the refrigeration system, and when the pressure is too high, it means that the refrigerant is too much, and the refrigerant should be reduced.

11.Refrigeration system too much refrigerantCheck the refrigeration system, and when the pressure is too high, it means that the refrigerant is too much, and the refrigerant should be reduced.

12.Compressor overload After measuring the power supply voltage of the compressor, if the compressor is found to be overloaded, the power supply should be reduced.

When the Meiling refrigerator compressor does not start, you can do a maintenance by yourself to see if it is faulty

1.Check whether the power supply of Meiling refrigerator circuit is turned on.

If the compressor does not start, it can generally be manifested from the power supply circuit, such as power failure, poor switch contact, fuse dissolution, etc., and these phenomena should be comprehensively analyzed to find out the root cause and eliminate it.

Exclusion method: (1) Check whether the input power supply circuit has electricity, that is, whether the line entering the knife switch has electricity, which can generally be measured with a multimeter and a voltage tester. If it is found that the dissolving filament is burned, the cause should be found out and replaced with a new dissolving filament according to the specifications.

2) Check the press accessories, including thermal protection and relays, bad thermal protection will cause the press to not be energized. The relay does not work generally after the press is energized, the motor does not rotate, and will emit a "buzzing" noise, in this case, it should be stopped immediately, otherwise the motor winding will be burned for too long. (3) Check whether the contacts of each connector are intact, whether the plug is tight, and whether there is any damage.

If there is a poor contact in the joint, the motor will not rotate or make a "humming" sound.

2.Check whether the circuit voltage of Meiling refrigerator is normal.

Fault analysis: If the circuit voltage is significantly lower than the rated value, the motor will not be easy to start and make a "buzzing" sound.

Exclusion method: Use a voltmeter to measure the voltage, if the voltage is low, you need to guide the user to buy a voltage regulator to increase the voltage value for operation.

3.Check whether the contacts of each relay of Meiling refrigerator are connected.

Whether the temperature relay contacts are on.

Failure analysis: Sometimes the contact contact is disconnected due to the leakage of refrigerant in the temperature sensing bag.

Exclusion method: Remove the cover of the relay box to check the contact, if it is jumped, it means that the original setting value is not adjusted, or the temperature sensor in the temperature sensor package is leaking, you can rotate the adjustment rod of the relay to the low temperature scale area. See if the contact is closed, if not, remove the temperature sensing plate and immerse it in warm water, and then see if the contact is moving, if there is no action, it can be preliminarily determined that the temperature sensor is leaking, and a new thermostat must be replaced.

4.Meiling refrigerator motor and electrical faults.

a Motor winding burned out or short circuit between turns.

Fault analysis: When the motor winding burns out or the turn is short-circuited, the fuse is often dissolved repeatedly, especially when the knife switch is pushed.

Exclusion method: Use a multimeter to check whether the binding post and the shell are short-circuited, and the resistance of each phase, if it is a short circuit or the resistance of a certain phase is small, it means that there is a short circuit between the windings and turns, and the insulation is burned. During the inspection, the insulation resistance can also be measured with a megohmmeter, if its resistance is less than 2m.

If the press burns out, the press can be replaced. , the insulation has been broken down. If the press burns out, the press can be replaced.

b. Control relay failure.

Failure analysis: Generally, the contact is prone to overheating, burning, wear, etc., which will make the contact poor.

Exclusion method: Remove for repair or replace with a new one.

c Poor contact of the temperature controller.

Failure analysis: Generally, there are contacts scorched or thermostat leakage.

Exclusion method: Replace with a new one.

d Check whether each terminal is not.

Line, butterfly protector or starter issues.

It may be because the refrigerator's plug and power port are in poor contact, or the plug cord is damaged and needs to be replaced. It is also possible that the circuit voltage of the refrigerator is lower than the rated value, and the transformer is replaced. The parts of the refrigerator compressor are missing lubricating oil, and lubricating oil is added to the parts that lack lubricating oil.

It may be that the temperature control cable is in poor contact, and the temperature control cable needs to be replaced. The specific reasons are as follows: 1. The power plug is damaged.

If the plug of the refrigerator is not in good contact with the power supply, or the plug wire of the refrigerator is damaged, the refrigerator cable will not be able to connect to the power supply normally, so it will not be able to start normally. Remove the food from the refrigerator in a timely manner and check the power socket, power cord, and plug for damage. 2. The power supply voltage is too low.

When the circuit voltage of the refrigerator is lower than the rated value, the motor of the refrigerator will not operate normally, and will affect the start or operation of the compressor, causing the refrigerator to fail to start normally. 3. Lack of oil in compressor parts. If the parts of the refrigerator compressor are lacking in lubricating oil, or if the parts are rusted due to moisture due to lack of use for a long time, it will be difficult to start properly.

4. Poor contact of temperature control line. If you rotate and twist the temperature control button to each gear, the refrigerator compressor will not have any running reaction, which means that the temperature control line is not in good contact and will cause the compressor to fail to operate normally, so the refrigerator will not start. It can be plugged back in.

If the fuse is broken, you can replace it with one. If it is a problem with the refrigerator plug, it should be replaced and repaired immediately. If the circuit voltage of the refrigerator is abnormal, then it is necessary to measure it with a voltmeter first, and then purchase a voltage regulator to help the refrigerator run.

1. Reason 1 for the refrigerator compressor not to start: it is boring.

When the refrigerator compressor does not start, first check whether the power supply of your refrigerator is plugged in or whether the power supply of the refrigerator is loose, the refrigerator is not well connected to the power supply, and the compressor of the refrigerator cannot be started.

Solution: If the problem is in the power supply, plug the power cord of the refrigerator back into the power plug to ensure that the refrigerator can fully receive power.

2. Reason 2 for the refrigerator compressor not to start:

The reason why the refrigerator compressor does not start may also be that the motor unit of the compressor is burned out, and the problem that will occur at this time is that the fuse of the compressor is blown and opened, which is a common problem for the compressor not to start.

Solution: The refrigerator compressor fuse blows and the compressor does not start, so you need to purchase a new fuse and replace it.

3. Reason 3 for the refrigerator compressor not to start:

If the controller circuit of the refrigerator fails, the general phenomenon is that the contacts are overheated, burned, worn out, etc., which will lead to poor contact of the refrigerator compressor contact head.

It may be a short circuit, or you are a broken compressor, you can find a professional maintenance personnel for repair.

Hello dear! I'm glad to serve you, the small one for you to inquire, how to repair the Meiling inverter refrigerator if it doesn't start? 1. The first search for power supply problems:

First of all, check whether the external slippery cresley power supply meets the standard requirements, use the multimeter AC file to test whether the external power supply is within the range of V 10% (or the requirements of the manual), if not, it is recommended that the user is equipped with a voltage regulator or find a professional electrician to deal with it. 2. Bad power socket (or switch): check whether the power plug and socket are in good contact with each other, and if the contact is not good, the user should be advised to replace or adjust the plug and socket.

3. Check the power indication or lighting: For refrigerators and freezers with power indicators, if the external power supply is normal, the lighting or power indicator should be on after power-on, indicating that the refrigerator and freezer have normal power supply. The voltage of the mechanical refrigerator lighting is V, and the voltage of the LED lighting controlled by the computer version is 5V.

Check whether the connector at the bottom of the box is in poor contact. 4. No frequency conversion signal: test whether the PWM end of the input square wave signal of the frequency conversion board is normal, and the voltage value should be between under normal circumstances, if the voltage value of the square wave signal output by the main control board is 0V or 5V, you can turn on the quick-freezing function through the display board, and then detect the PWM signal voltage If it is normal, focus on checking the frequency conversion board and compressor.

If it is not normal, check the display board and power board. 5. Frequency conversion board input voltage detection: detect whether the input voltage of the frequency conversion board socket is normal, and the normal is about v, otherwise there is a problem with the line from the power supply to the frequency conversion board.

I hope it helps you and I wish you a happy life <>

Hello dear, I am happy to answer this question for you, the following is the solution for Meiling refrigerator not starting: 1, when the refrigerator compressor does not start, first check whether the refrigerator power supply is plugged in or whether the power supply of the refrigerator is loose. The refrigerator is not well connected to the power source and the refrigerator's compressor does not start.

Then, if the problem is with the power supply, plug the power cord of the refrigerator into the power plug to ensure that the refrigerator can be fully plugged in. 2. The control circuit of the refrigerator is faulty. The general phenomenon is contact overheating, combustion, wear, etc., which will lead to poor contact of the compressor contacts.

Then it is very harmful, at this time, you need to remove the contacts of the refrigerator for repair or replace the contacts of the refrigerator.
