5 Easy DIY Electrical Repairs for Your Home

More often than not, homeowners like to do things on their own. This article is for homeowners who have a basic knowledge of how electricity works. Here are some electrical repairs you can do yourself.

Electrical Repairs

Fix a faulty doorbell

There are many reasons why your doorbell is not working. Here’s what you can do to find the source of the problem. First, inspect the wires by detaching the button from the wall. If everything looks good and the wires are intact, make sure to clean it and tighten the screws. If it doesn’t work, detach the wires from the terminal. Hold each wire by its insulation, then gently touch the bare wires together. A spark and a sound from the doorbell mean you need to replace the button. A spark without a sound means your chime might be faulty. And no spark means the transformer is the problem. 

If your problem roots from the chime, test it by using a multimeter tester to take a reading. Set the chime to AC. Touch the probes to the “front” and “trans” terminals, then the “rear” and “trans” terminals. You need to replace your chime if the reading you get is between 16 and 24 volts which mean power is reaching your chime. 

Lastly, you need to test the transformer if there is no power to the chime. You can do this by removing the thin wires and touching the multitester probes to both terminals. You need a new transformer if the reading is more than four volts below the transformer’s output rating. 

Fix a loose outlet – one of the easiest electrical repairs

It’s hazardous to find your electrical outlet moving in its box. This could loosen your electrical wires and compromise the safety of your family. A loose outlet is one of the easiest electrical repairs to do.

Here’s what you can do to fix this. First, turn the power off and use a voltage tester to make sure no power is running to the outlet. Second, unscrew the cover plate and the outlet. Third, check if the outlet is recessed too deeply. If it is, add shims to the screws until the outlet sits flush with your wall. Lastly, screw the outlet back into the box and replace the cover plate.

Find an electrical short

You can find the source of a short by turning on an appliance. First, reset the breaker and try the appliance again. The problem is probably the appliance if the short happens again. However, if the short happens when the appliance is unplugged, the problem is most likely in the wiring or receptacle. 

Second, remove all cords and plugs from the outlet, then turn the power on to the circuit to see if the short has been cleared. If it’s still present even after unplugging everything, switch your breaker off or remove the fuse at the main electrical panel to ensure that the power is completely turned off. 

Third, remove the receptacle from the box using a pair of insulated pliers. Check each of the wires using the “Ohm” setting on the volt/Ohm Meter. Connect one lead of the testing meter to the black wire and the other to the white wire. When the meter reads ZERO or “OL,” there is potentially a dead short within the circuit wiring. This process should be repeated utilizing all three wires until all wires have been checked against one another.

Lastly, read community between the white and green or white and the uninsulated wire (Ground). Continue to remove the other receptacles, switches, and/or light fixtures from the circuit once you confirm the presence of the community using the black wire. Check the circuit continuously using the Ohm meter after removing each device. You will locate the trouble once the community reading had cleared. 

NOTE: 

Never test the wiring inside the electrical panel. It is very dangerous and lethal. Make sure to call a skilled electrician to do complex electrical repairs for you.

Repair an Extension Cord End

Repairing a cord that has been cut or damaged near the plug is pretty simple. 

First, cut off the old plug then cut back the insulation jacket (do this by making a light, lengthwise incision, then score it gently until you can peel back the jacket). Use a wire stripper and gauge to strip each of the wires, then twist each tightly. After this, screw them into the back of the plug (black wire to gold screw, white wire to silver screw, green wire to green screw). Make sure to close the plug and secure the wires after. 

When fixing a cord that’s damaged in the middle, cut it in half and add new male and female ends to each half. This will turn your one damaged cord into two new cords.

Repair an Electric Stove

Before repairing an electric stove, you need to find the root cause of the problem first.  You can first try switching out the burner with one that works by unplugging the burner from the socket and plugging in the prongs of the other burner. 

Check if the socket looks corroded and charred if the burner doesn’t work. If it is, you need to replace it with a new one by unscrewing the old one from the socket, unscrewing its wires, and connecting the wires to the new socket.

If the socket looks fine, test the switch by using a multimeter tester. First, find out where your infinite switch is located. Turn on the damaged burner and remove the wire from the H1 terminal. Set your multimeter to RX-1 and place the two probes on the H1 and H2 terminals. You need to replace your switch if the meter doesn’t change. It’s better to have an electrician do this for you.
