Repairing electricity at home can be difficult, especially for people who are not familiar with it. Knowing the basics of electrical repair is important to keep the appliance working and protect your safety and your family.
However, handling electricity without sufficient knowledge can be dangerous. If preventive measures are not taken correctly, risks such as short circuits, burns, or fire can occur. Therefore, it is important to understand the basic techniques and know when to call an expert to avoid danger.
Common Electrical Problems in the Home
Electricity is very important in daily life, but often problems arise that can interfere with activities. Here are some electrical problems that often occur in homes and need to be fixed immediately:
1. Sudden Power Outage
A sudden power outage can make the house dark and all activities stopped. This can be caused by a fault in the power grid, overloading the circuit, or damage to the MCB or GFCI in the home’s electrical panels.
2. Socket or Plug Feels Hot
If the socket or plug feels hot during use, it indicates a problem with the electrical connection. The cause can be dirty contacts, old wires, or overload on the socket. If left unchecked, this can lead to a short circuit or fire.
3. Lights Often Turn Off or Flicker
This problem is usually caused by loose connections, lamp wattage that does not match the capacity, or the use of low-quality lamps. In addition, components such as dimmer switches that do not match the LED lights can also be the cause.
4. Power Tools Not Working Properly
Household appliances such as microwaves, refrigerators, or irons that suddenly malfunction may have internal problems or cause a trip circuit. This often happens due to electrical overload or damaged appliance components.
How to Solve Electrical Problems at Home
Solving electrical problems at home requires proper and safe steps. Here is a simple guide to some common issues:
1. Check the Electrical Panel
a. How to Safely Check MCB or GFCI
- Make sure your hands are dry before touching the electrical panel.
- Use a small flashlight to see conditions in the panel, especially in dark places.
- Check for MCB (Miniature Circuit Breaker) or GFCI (Ground Fault Circuit Interrupter). If one of the switches is in the “Off” position, this could be the cause of the power outage.
b. How to Turn on Electrical Power
- Determine if the outage occurs throughout the house or just in one circuit.
- If it’s only one circuit, return the MCB or GFCI position to “On.”
- If the power goes out when switching on a particular appliance, turn it off before attempting to turn the MCB back on.
- If power is still interrupted, unplug all tools from the circuit and try again. This can help find problematic tools.
2. Overcoming Hot Sockets
a. Clean Contact with Fine Sandpaper
- Unplug all devices from the socket.
- Use fine sandpaper to clean the prongs on the plug and contacts in the socket to prevent oxidation.
- Keep the socket dry before using it again.
b. Replace Damaged Sockets or Cables
- If the socket is still hot after cleaning, consider replacing it.
- Carefully unplug the old socket using a screwdriver, then install a new socket with the same specifications.
- If heat is coming from the power tool cord, replace it or contact a technician for further inspection.
