4 way switch troubleshooting

4 way switch troubleshooting. I was in my home, it was getting late for me to sleep. My home has 3 floors and each floor has 4-way switch. I was about to sleep, lights on the top floors were switched on and I was tired enough not to go up on the floor to switch of the lights.

I had a 4-way switch and I tried to avail it because it would have not only got me the desired result but at the same time, it would have also saved me some time. But when I tried to use it I found out it wasn’t working for me.

It was indeed something unacceptable for me at that moment, because I had to go to the top floor to switch off the lights.

From this experience, I learned that we should know a little about our home electric system, we shouldn’t be totally dependent on professional electricians because sometimes blue electrical systems can demand quick troubleshooting and repair.

I then got some understanding of the wiring work of the 4-way switch and this helped me in life a number of times whenever I faced any sort of problem in it.

You may also have gone through similar experiences like this and in the future you also you can have such experiences again.

Therefore I am here to share my research with you about wiring and troubleshooting so that when you face it next time you can do it on your own without the help of professionals and spending some money.

Troubleshoot a 4-way switch

In the following points, you will be able to understand how to troubleshoot a 4-way switch.

First, you need to find space in between two 3-way switch terminals and there you have to connect the 4-way switch.

In the 4-way switch you will get to see 5 terminals, one terminal is ground terminal, 2 terminals are traveler terminals and 2 terminals are common terminals. What you have to make sure about them is that they are properly connected.

If you want to see your 4-way switch working properly, then you have to make sure your 3-way switch is working properly. What you have to make sure here is that you connect the common terminal of one of the two 3-way switch to the power source.

Another point that should be kept in mind is that traveler wires should only be connected with the traveler terminals of switches. Many people often end up connecting traveler wires with common terminals and ground terminals which makes their efforts futile.

You also have to make sure that 4- way switch is connected only to traveler wires, not to another type of wires such as hot and wire that is neutral.

If you know everything is well in order then it should be smoothly functioning, but if you see the problem is still there, the problem persists, then you must test the switch.
