Have you ever felt like a refrigerator is shocking? At the slightest touch on the metal body, tingling occurs. So, a small charge passes through it. Do not let things go by themselves, because such a “behavior” of technology indicates a malfunction of the refrigerator components or that the insulation of the network cable is broken.
Precautions must be taken so that neither you nor your family are hurt.
Why the refrigerator is shocking
The cause of the malfunction and breakdown of the current to the case could be the refrigerator motor-compressor. Unpleasant sensations occur when touching the case, especially in such cases:
- You touched the surface with wet hands.
- With one hand you touched a heating battery, with the other a refrigerator.
The risk of electric shock increases if the floor is cemented and there is no insulation. At the first sign of a breakdown on the refrigerator body, immediately disconnect it from the power supply.
The main causes of the malfunction:
- Damage to refrigeration equipment. Malfunction of components and parts.
- Lack of grounding. Usually, in old Soviet-built houses, grounding on sockets was not installed.
To correct the situation, you need to find the cause of the breakdown. You can immediately call the wizard, who himself will deal with the problem. You can also independently check for grounding.
Before diagnosing, follow these recommendations:
- Be sure to unplug the refrigerator to avoid electric shock.
- Inspect the network cable. If the insulation of the wire is broken, do not repair. It is better to completely replace the cable.
- If you understand refrigeration, you can strip the contacts on the compressor.
It is necessary to consistently check all components and parts of the refrigerator for serviceability.
What to do to restore the operation of equipment
Each electrical appliance is connected to a power outlet and must be earthed for safety reasons. But in reality this is not always the case. How to check the room:
- Perform a visual inspection. If the socket is an old model with a simple panel, the hole is unprotected, then there is no grounding there.
- You can remove the external panel and check the wires. Grounded products have three wires, and ordinary - two.
Check more accurately and reliably help a multimeter. This device allows you to measure voltage. The method is suitable for modern outlets that are equipped with a grounding contact. What to do:
- Attach one multimeter probe to this pin.
- Insert the other probe first into the first, then into the second hole in the outlet. The readings should be 220 - 0 V. If nothing is displayed on the screen or the readings jump, then the grounding is broken and does not work.
Further, if the readings are positive, switch the multimeter to resistance measurement mode. Important! Remember in which hole the multimeter showed 0 V, this is useful for the following test:
- Apply one multimeter probe to the ground terminal, the other to phase 0 V.
- A resistance of 4 to 10 ohms is considered normal.
If the socket does not pass the test, there may be a reason for the lack of grounding between the socket and the plug.
To make grounding in a house or apartment, buy a special outlet. Then you need to hold a three-wire wire to it. What is it for:
- to exclude electric shock when touching the refrigerator;
- ensure stable operation;
- reduce electrical interference that may cause a short circuit.
In any case, if the equipment is shocking, you need to contact the master so that he carries out a diagnosis, eliminates the possibility of breakage. Otherwise, such a malfunction may result in a fire.
