After the refrigerator at home is used for a period of time, it is necessary to clean up the frost in the refrigerator. Many people find that the refrigerator can't start except for frost. So what is the reason for this situation? Next, I will introduce the reasons for the failure of the refrigerator not to start after defrosting and the solutions. Let's take a look together.

Does the refrigerator not start after defrosting? Causes and solutions of power supply

Reason 1: When the refrigerator compressor does not start, first check whether the refrigerator power supply is plugged in or whether the refrigerator power supply is loose. If the refrigerator is not well connected to the power supply, the refrigerator compressor will certainly not start.

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

Does the refrigerator not start after defrosting? Cause and solution of fuse

Reason 2: The reason why the refrigerator compressor does not start may also be that the motor group of the compressor is burned. At this time, the problem will be that the fuse of the compressor is blown, which is a common problem when the compressor does not start.

Solution: The fuse of refrigerator compressor is blown, which causes the compressor not to start, so it is necessary to buy a new fuse and replace it.

Does the refrigerator not start after defrosting? Contact Causes and Solutions

Reason 3: The controller circuit of the refrigerator is out of order, and the common phenomena are overheating, burning and wear of the contacts, which will lead to poor contact of the compressor contacts of the refrigerator.

Solution: Remove the contact of the refrigerator for repair or replace the contact of the refrigerator.

Does the refrigerator not start after defrosting? Voltage causes and solutions

Reason 4: Check whether the circuit voltage of the refrigerator is normal. When the circuit voltage of the refrigerator is lower than the rated value, the motor of the refrigerator will not start easily and send out at the same time. Buzzing? The sound.

Solution: First, measure the voltage with a voltmeter. If the voltage is low, you need to buy your own power regulator to increase the voltage to make the refrigerator run.

Does the refrigerator not start after defrosting? Lubricating oil fault and its solution

Reason 5: The mechanical failure of the compressor will also cause the refrigerator compressor not to start. The shaft locking problem of compressor is generally caused by 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. The compressor cylinder is stuck because the fit gap between the piston and the cylinder is small or the thermal expansion relationship is stuck.

Solution: If there is a fault caused by lubricating oil, the lubricating oil is not enough to add lubricating oil, and the viscosity of lubricating oil pipe and lubricating oil increases, it is necessary to replace the lubricating oil. If the problem is that the compressor cylinder is stuck, it is necessary for professionals to repair it.

Above, I'll stop here for some introductions about the refrigerator not starting after defrosting. After reading the above contents, everyone should realize the cause of the failure and how to solve it. So as to calmly deal with the problem that the refrigerator does not start after defrosting. I hope my introduction will help you.
