Reasons why refrigerator compressor does not work and how to solve it

1. Refrigerator compressor.

Hot not cold. 1.The refrigerator compressor heats up.

The problem of not cooling may be the refrigerator thermostat.

Caused by a failure of control;

2.The high-pressure output buffer pipe in the compressor is broken, or the screw fixing the tube is loose, resulting in the phenomenon that the high-pressure pipe does not exhaust and the low-pressure pipe does not suction, so although the compressor is running, it is not refrigerated;

3.If the temperature inside the refrigerator does not drop, it may be that the capillary is clogged, resulting in the refrigerant.

There is no access to the vaporizer.

Evaporation absorbs heat, and the internal temperature of the refrigerator does not drop.

Second, the refrigerator compressor is buzzing all the time.

1.If the fridge emits a muffled humming electromagnetic sound, the possible causes of this phenomenon are:

1) The possible reason is that the grid voltage is too low, which makes it difficult to start the refrigerator compressor;

2) Fuse.

The connection points between sockets, plugs and other components and wires are loose, which will cause intermittent situations;

3) Insufficient or deterioration of capacitance in capacitors.

2.The refrigerator emits a heavy humming electromagnetic sound due to an overloaded compressor, which is caused by:

1) The refrigerator is affected by hot summer or other heat sources, resulting in an increase in ambient temperature and a humming sound;

2) Too much refrigerated and frozen food;

3) The refrigerator door is not closed tightly or the door is opened too many times;

4) Put the thermostat on strong cold 7 gear.

3.What is the reason why the refrigerator compressor is not working?

1.The refrigerator compressor is not working due to a power outage or poor contact;

2.It could also be that the compressor is not powered up. At this point, the temperature controller should be checked. It may be because the thermostat temperature bulb is leaking and the thermostat contacts are burned out.

3.It may also be that the motor unit of the compressor is burned out, and it only needs to be replaced with a new fuse in time to repair it;

4.It can also be caused by low ambient temperatures. When the ambient temperature is below 0, the compressor oil of the refrigerator thickens and the lubrication performance deteriorates.

At the same time, the condensing pressure of the refrigerator compressor is lower, and the refrigerant does not flow into the evaporator. If the refrigerator is forcibly used, not only will it not work properly, but it may also cause damage to the compressor.

Possible causes and solutions: The refrigerator power supply is not plugged in properly, just plug in the power cord tightly; The motor unit of the compressor burned out and the fuse needed to be replaced; The circuit of the controller is faulty, and the compressor contacts need to be repaired; If the circuit voltage is abnormal, install a power regulator to solve the problem; The compressor's machinery is faulty and needs to be lubricated or repaired by a professional. Specific causes and solutions:

1. The refrigerator power supply is not plugged in or the refrigerator power cord is loose, the refrigerator cannot be well connected to the power supply, and the compressor cannot be started. If the problem is in the power supply, you need to plug the power cord of the refrigerator back in and plug it firmly to ensure that the refrigerator can fully receive power and the compressor can operate normally. 2. When the motor unit of the compressor is burned, the fuse of the compressor is blown out, which is a common problem that the compressor does not start, and a new fuse needs to be purchased and replaced.

3. If the controller circuit of the refrigerator fails, the general phenomenon is that the contact is overheated, burned, worn and other phenomena, which will lead to poor contact of the refrigerator compressor contact. The compressor contacts need to be removed for repair or replacement. 4. The circuit voltage of the refrigerator is abnormal, if the circuit voltage of the refrigerator is lower than the rated value, the motor of the refrigerator will not start, and it will make a "buzzing" sound.

The voltage needs to be measured with a voltmeter, and if the voltage is low, a power regulator can be installed to solve the problem. 5. The mechanical failure of the compressor will also lead to this problem. The problem of holding the shaft in the compressor is generally caused by the lubricating oil, which is caused by the blockage of the lubricating oil circuit, the interruption of the oil supply, and the increase of the viscosity of the lubricating oil due to the dirt in the lubricating oil.

The compressor cylinder is stuck because of the small gap between the piston and the cylinder or the thermal expansion relationship. If the fault caused by the lubricating oil, the lubricating oil is not enough to add the lubricating oil, and the viscosity of the lubricating oil pipe and lubricating oil increases, the lubricating oil should be replaced. If the problem is that the compressor is jammed, it is necessary for professionals to repair it.

1. If the refrigerator does not run after connecting the power supply, first rule out whether the voltage of the externally connected power supply is too high or too low, if the voltage is unstable, you need to turn off other electrical appliances at home, and then use the refrigerator. 2. If the fuse of the compressor is blown out, it will cause the compressor to not work, and the fuse needs to be replaced again. 3. The compressor does not work after the refrigerator is energized, or it may be that the compressor does not work due to the failure of the protector, so you need to ask a professional maintenance personnel to come to the door for maintenance.

Relevant popular science knowledge: 1. If the voltage of the external power supply is unstable, it is necessary to configure a voltage regulator for the refrigerator to ensure the safe and stable operation of the refrigerator. 2. Check whether the refrigerator compressor is damaged due to improper operation, and if the refrigerator compressor is damaged, it should be repaired or replaced with a new compressor.

When replacing the compressor, be sure to pay attention to the compatibility with the refrigerator. 3. Another reason why the refrigerator compressor does not work is that the deviation between the set working temperature and the actual temperature is too large, so the temperature gap should be narrowed, and then gradually adjusted. 4. It may be that the unit is damaged due to unstable voltage and excessive current, and it needs to be replaced by professionals.

5. If there is an abnormal sound after the refrigerator is powered on, it can be determined that the compressor does not work due to the failure of the protector contact reed. This is where repairs are needed.

1. The power supply is not plugged in properly

If the power supply is not plugged in, the compressor will naturally not start. As soon as it is plugged back in, the freezer receives power and the compressor is back in normal use.

2. The circuit of the controller is faulty

Problems with the control circuitry, such as overheating, wearing, or burning contacts, can lead to poor compressor contact. Simply wipe down the compressor contacts or replace them with new ones.

3. The refrigerator voltage is abnormal

If the voltage is unstable and below the rated voltage value, the compressor will not start, and there will be a "buzzing" sound. Start with a voltmeter.

Test the voltage, if the voltage at home is indeed too low, it is recommended to buy a power regulator to increase the voltage.

4. The compressor motor unit is burned out

If the fuse in the motor unit of the compressor.

burned, which will cause the compressor to fail to start. Replace the fuse with a new one.

5. The ambient temperature is too low

If the ambient temperature is too low, the temperature of the refrigerator will rise slowly or even not at all, so the compressor will not work, and the compressor will be damaged for a long time. When the temperature is too low, turn on the temperature compensation switch first.
