When you turn on the refrigerator knocking caps? As soon as the engine started to work, you suddenly noticed that the display and the lights on the refrigerator went out, and the room became unusually quiet?
The machine does not knock out just like that, there is a malfunction that needs to be fixed. This could happen immediately after the equipment was included in the network or after a certain time. What caused the problem, we will consider in the article.
Why, when you turn on the refrigerator, it knocks plugs
An RCD fuse is installed specifically to save equipment that consumes a lot of electricity. Expensive household appliances must be installed correctly, and their electronics must be protected against power surges. Therefore, if an RCD circuit breaker is knocked out when starting the refrigerator, there is a problem.
The reason is not necessarily the breakdown of the refrigerator components. Look, maybe you have a similar situation:
- You have connected new refrigeration equipment. The network overload is to blame: the old wiring, unprepared Soviet-made electrical panels are not ready to withstand the voltage of modern appliances. Therefore, you need to replace the wiring or install new network protection systems.
- Several devices are connected to the network. Remember what power machine you installed? Exceeding the installed capacity in the network will disable the protection. Therefore, turn off one of the devices.
You should be alerted by the situation when traffic jams were knocked out when the motor-compressor was turned on, although this had not happened before.
- Broken plugs or a power cord is serious. Shorted contacts can cause a fire, so it is recommended that you contact an electrician. You also need to check the outlet for proper operation.
Overvoltage protection for the refrigerator - protection of equipment from breakage. However, if it turns off, replacing the machine will not help. We need to look for the reason for this behavior.
What malfunctions lead to a power outage
If you checked the wiring and the power cord, but did not find a breakdown, the reason could be a serious malfunction of the Nord, Atlant, or other brand refrigerator components.
Violation of the motor compressor
From the voltage drop in the network, the motor winding may short circuit. It is possible to determine that the cause is a compressor malfunction if the plugs are knocked out immediately after starting the motor. Verify the problem by checking the winding with a multimeter. To do this, the multimeter probes are applied to the contacts and the compressor winding. Resistance may vary depending on the make of the manufacturer.
If the resistance of the windings is 0, then you need to replace the motor. This is a fairly serious repair, so it is better to call the master.
Start relay failure
The start-up relay serves to supply voltage to the windings of the refrigerator engine. When the equipment is connected to power, the machine will immediately knock out, and you will hear a characteristic click. Unfortunately, relay repair is not possible, so a new part is installed.
Failure of the evaporator heater
The No Frost defrost system is equipped with a heater that could have failed. As soon as the heater turns on, the overvoltage protection switches off immediately. After supplying electricity, the refrigerator will work, but as soon as the heater turns on, the electricity will turn off again. Need to replace the item.
What other failures lead to a power outage:
- The keys on the panel burned out. As a result of combustion or shorting of contacts, the RCD knocks out. You may notice that the keys on the panel began to melt.
- The same thing happens when a circuit board malfunctions.
Overvoltage protection for the refrigerator
Protection against surges in the network for household appliances is used in the form of an RCD machine or grounding outlets.
You need to be careful when choosing, since the machine can be of poor quality. If you come across a fake, which is assembled from third-rate plastic, save on details, then it will not work for long. After two trips, the machine deteriorates, so even when the low-power device is turned on, it starts to turn off. Then you need to install a new machine.
If you notice that a shield is knocked out when connecting the refrigeration equipment or the light in the room blinks, do not try to reconnect the equipment. This can be dangerous, because it threatens not only with a shock, but also with a fire. Therefore, if you notice a problem, call the repairman or electrician.
