What s going on with the refrigerator compressor not working

The main reasons are: 1. There is no power supply for the external power supply of the refrigerator and the input voltage of the compressor; 2. The ambient temperature of the refrigerator is set too low; 3. The refrigerator thermostat or main control board is abnormal.

Suggested workaround:

Open the refrigerator door to see if the indicator light is on, if it is on, it means that the power supply is fine, if not, you need to check whether the external socket power supply is not, and then turn on the power supply after the power is available.

The ambient temperature is too low. If the ambient temperature of the refrigerator is relatively low, if the temperature of the refrigerator is 1 degree Celsius for a short period of time? 10 times, often the refrigerator compressor is in a state of not running for a long time, so when the ambient temperature is too low (1?

10), if the refrigerator is manually compensated, the compensation switch needs to be turned on.

If the thermostat or main control board is abnormal, remove the thermostat. Use a multimeter to measure the power contact with the multimeter contact and the compressor input contact is on, if it is on, then check the thermostat temperature tube for breaks, cracks, leaks, if necessary, the thermostat needs to be replaced.

If the refrigerator compressor is not working, if the test compressor accessories are normal, but the shrinking machine still cannot start, it may be an internal fault of the compressor. Ask the maintenance master to come to the repair.

In addition, if it is caused by moisture, you can remove the motor and put it in the drying oven to dry.

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. 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.

There are two possibilities:

The ambient temperature is too low.

When 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, and if the magnetic temperature compensation switch is used, you need to check whether the magnetic switch is normal: because the ambient temperature is too low, especially for the refrigerator of the dual-temperature single-control refrigerator.

Failure of the overload protector.

Use the ammeter to measure whether the compressor start-up and running current are normal (the starting current is generally about 5 8 times of the operating current), if the current is normal and the overload protector acts, the overload protector fails and should be replaced. Otherwise, the compressor is faulty.

First of all, see if the compressor is broken, if it is not broken, it may be that the compressor plug plug is burned out, basically these two situations.

The refrigerator compressor does not work, there are many reasons, if it is not that the temperature is too high, it is that the refrigerator is broken, and I am really helping you look forward to it

It may be that the compressor is damaged, or the compressor lacks refrigerant, and the common ones are that the circuit of the compressor is faulty, the motor unit may be burned, or the fuse of the compressor is blown out.

1. Confirm that the refrigerator has electricity and the compressor does not start, first check the motor unit of the compressor to see if it is burned, generally this reason is the most common, and at the same time, the fuse of the compressor may be blown because of the impact of excessive current, resulting in the compressor power failure, so first check whether the motor around the compressor is normal.

2. If the controller circuit of the refrigerator fails, the general controller circuit may be powered off due to overheating, burning, wear, etc., and the poor contact of the compressor is the most important manifestation.

3. In addition, in some areas, due to the unstable voltage, it may also lead to abnormal circuit voltage of the refrigerator, when the circuit voltage of the refrigerator is lower than the rated value, the motor of the refrigerator will not be easy to start, and it will make a "buzzing" sound. This requires professional maintenance personnel to test whether the voltage on both sides of the compressor is stable.

4. The compressor will also have mechanical failure, which will also cause the refrigerator compressor not to start. The problem of holding the shaft of the compressor is generally caused by the lubricating oil, the lubricating oil circuit is blocked or the oil supply is interrupted, and the dirt in the lubricating oil increases the viscosity of the lubricating oil, resulting in the compressor jamming.

It may be that the compressor is damaged, or the compressor lacks refrigerant, and the common ones are that the circuit of the compressor is faulty, the motor unit may be burned, or the fuse of the compressor is blown out.

1. To confirm that the refrigerator is well equipped and the compressor does not start, first check the motor unit of the compressor to see if it is burned, generally this reason is the most common, and at the same time, the fuse of the compressor may be blown because of the impact of excessive current, resulting in the compressor power failure, so first check whether the motor around the compressor is normal.

2. If the controller circuit of the refrigerator fails, the general controller circuit may be powered off due to overheating, burning, wear, etc., and the poor contact of the compressor contact code is the most important embodiment.

3. In addition, in some areas, due to the unstable voltage, it may also lead to abnormal circuit voltage of the refrigerator, when the circuit voltage of the refrigerator is lower than the rated value, the motor of the refrigerator will not be easy to start, and it will make a "buzzing" sound. This friendly model means that professional maintenance personnel need to test whether the voltage on both sides of the compressor is stable.

4. The compressor will also have mechanical failure, which will also cause the refrigerator compressor not to start. The problem of holding the shaft of the compressor is generally caused by the lubricating oil, the lubricating oil circuit is blocked or the oil supply is interrupted, and the dirt in the lubricating oil increases the viscosity of the lubricating oil, resulting in the compressor jamming.
