Electricity randomly off & on in one room?

Check to see that the wires in your fuse box or circuit breaker box are all tight. You will need to turn off the main power then use a screw driver with a rubber or plastic handle to tighten the screws that hold the wires

If you have checked the circuit breakers and all is good there, you probably have failing connection in a receptacle (outlet) or switch.

Here is a method to find the problem. Not 100% guaranteed, but works almost all of the time. If it doesn't, you will be stuck opening each receptacle on the circuit until you find the problem.

Turn on all of your non-working lights and plug lamps into any non-working receptacles. Make sure that any computers, or other sensitive electronics are not plugged into this circuit. Take a lamp or an extension cord around to the all of the receptacles on this circuit. DON'T rule out the working receptacles either. Try them too. Plug it in and wiggle the plug (hard enough to wiggle the receptacle too). You will probably find one where doing this suddenly causes your non-working lights/receptacles to come back to life. This will be your culprit.

A lot of homes are wired with receptacles using 'stab-in-the-back' connections. These are actually still in use and are deemed safe for installation. The problem is that they have a terrible failure rate. The term 'stab-in-the-back' also applies to what they do to you later. Any replacement should have screw terminal connections.

It sounds as in case you have a loose connection and vibration is casing some moving, The lighting fixtures would desire to be on a separate breaker so they are no longer being affected. get rid of your electric merchants one after the other and examine for any loose connections. If no longer something is discovered , examine the breaker for those merchants and notice if there's a loose cord there. If nevertheless you hit upon no longer something , call an electrician in to income issues out, no count if that's a loose connection it might desire to easily start up a hearth. be sure you close the breaker off to the merchants in the past removing them. desire that helps you , stable good fortune.
